Wi-Fi - to the masses!

How wonderful that the wireless standards are included in our daily lives, making it easier and more pleasant. Many of you probably already appreciate beauty Bluetooth - and synchronize their PDAs with mobile phones, and out of GPRS to the Internet. Unfortunately, one of the most serious shortcomings of this pioneer of wireless technology - low data rate and a small range - up to 10 m. The Bluetooth does not allow you to lay on the couch with a palm in one room apartments, to connect remotely to a desktop PC, which stands in the other room, listening to his music, surf the internet and always within your home (no matter how big he may be) stay in touch. Therefore use "blue tooth" for the construction of personal wireless paradise (read - "Network") in the native penates or office is not very convenient. In this case, the aid will actively developing in our country and is already firmly entrenched overseas standard Wi-Fi. Another argument in favor novelty acts that today, especially in major cities such as Moscow and St.-Petersburg, started a mass deployment of wireless networks in public places - hotels, airports, restaurants and cafes. Wireless Internet is becoming more and more, and it's time we would learn to use it.

Once you say, "Wi-Fi? ..

First, draw a small educational program - for those who are not quite up to date and to clear my conscience. Wi-Fi - is a resounding abbreviation of Wireless Fidelity, its official name - IEEE 802.11b. Standard originated in the West in the 90's, but the mass distribution only began in 2000, Wi-Fi stands out his "teeth" competitor and beats it in almost all parameters. Brief technical characteristics of the two channels are shown in Table 1. What is the hero of this review is really losing, so it is in power consumption. Increased range and just explain the increased "voracity". A "eats" the adapter properly, about 100 mA in standby and 250 mA in transmit mode. In fact, it is reflected in a reduction of time of continuous battery life - approximately 15-25%. The core of the wireless Wi-Fi network is an access point (Access Point), which is connected either directly to a hub (switch) or to a personal computer, as The compound with a wired network or direct to the Internet. All the users are within range of an "access point", can also connect smoothly through it to all network resources as if everything was done by cable. Possible in the network and another way to connect - "computer to computer, more suited to domestic conditions, as it does not require installation of Access Point. In this case, wireless adapters, one of which will be installed, for example, a desktop PC, the other - the PDA can be configured for direct communication with each other. With this bundle you will have access to everything that is on your PC: if you want - see the movie, you want - listen to music, you can even synchronize. No wires. All happiness will cost 70 EUR But in my case the Access Point still present in her role made D-Link DWL-700AP. Alas, if all limited to only a small amount of money spent, then the meaning of this article was not, so go to the heart. Thus, the proposed material, you are considered the most common problems (and, of course, their solutions) encountered by users of the PDA when you try to taste the Wi-Fi-charms of civilization. Before you close our experimental set, consisting of a PDA HP iPAQ h2210 running Windows Mobile 2003 (!) And Wi-Fi adapter, Pretec CompactWLAN map CompactFlash.

What to take?

In my personal experience I can say that the least difficulty have users that have built-in handheld wireless adapters are Wi-Fi. Have not heard that from someone with models like the HP iPAQ h4150 (on board - Bluetooth and Wi-Fi), there were problems. So if you have a PDA yet, but use the wireless features you expect, you take care of this in advance. If the PDA you already have, but not full of trendy integrated fashion, as in our case, we will start with the purchase of Wi-Fi adapter, where you and await the first pitfalls. Wireless adapters on the market quite a lot - for every taste and color. There is a classic - based on the cards Compact Flash, and there are new-fangled, like Wi-Fi SD Card with embedded memory on board. What to choose - it's up to you. As practice shows, the perfect card to work flawlessly the software has not yet been released. This, in turn, means one thing - the user will have to overcome all difficulties on their own. Well, we're not used to retreat ... And yet, a recommendation for the adapter is - it is desirable that the map attached to the acquired set of drivers and software specifically for your operating system. That is, if your OS - Windows Mobile 2003, then in the description and the manufacturer's site should always be written specifically about the compatibility with it. When I acquire Wi-Fi card Pretec CompactWLAN (under the CF slot) I did not pay attention to this point, but since the manufacturer specifically configured to support only Pocket PC / Pocket PC2002/WinCE3.0. As it turned out, this does not mean automatic support for Windows Mobile 2003. Therefore, we begin with the problems that may arise at the stage of installing the module.

Put Wi-Fi

So, acting on instructions, you have inserted into the socket adapter, installed all drivers and any software, but software is not working or not working properly. For example, in my case, the accompanying utility refused to see located a meter away from my access point, through which he successfully worked as lying on a table next to the laptop. Also, the utility may simply not detect the adapter. Such cases are too.

Possible solutions:
1. Perform Soft Reset on the PDA. If you do not help, then make a backup copy of all data, Hard Reset, followed by re-reinstalling all the drivers.
2. Update the firmware device. For PDA HP iPAQ h2210, yes, and any other series h22hh update is available at HP, Make your Hard Reset and reinstall software from scratch.

If you have not helped, and the above measures, it is your Wi-Fi card and "did not see" the access point or reaching complete tool and did not recognize the adapter, then you are faced with a problem that HP specialists in one of the overseas sites were classified as someone elses problem. The gist of it is precisely in the fact that install software that came with Wi-Fi card, designed for Pocket PC 2002, not Windows Mobile 2003. And can you make money ... and can not earn. By itself, the problem seems rather strange. What does that mean that the producer of the periphery does not want to provide software support for your product? Let's not boil, and assess the situation, especially from the standpoint of the producer. It is surely released over the past two years, a lot of wireless devices, and each of their "pets" adapted to work with those operating systems, which at that time were present in the market. So what happens periferiyschiki not their fault that, in turn, manufacturers of PDA (and this is their fault and HP in particular) have not provided your PDA fully compliant with the periphery of the previous generation of Pocket PC. And it is a fact that will not argue.The most surprising thing is that the same cards from different manufacturers may be perfectly normal to work with some models of handheld devices for Pocket PC 2003, but not "perceive" other. The whole point is that the operating systems installed on different handhelds to the same manufacturer - always different. And about the different manufacturers - and say nothing. Moreover, the same adapter you can not earn, and at exactly the same PDA to your neighbor - the perfect function. So, for example, turned in my case. Pretec CompactWLAN, I have taken for the experiments without problems on my HP h2210 friend. I was just unlucky. However, my case turned out to be called inoperable, and a lot of users, primarily Western, has already solved this puzzle. One of the standard ways to solve "the problem of older drivers" - the use of software from other vendors. Most of the Wi-Fi cards are based on PRISM chipset and drivers for them are compatible, so the first thing we remove the old drivers. Then go to the ASUS website and download fresh for the wireless card ASUS WL-110 (in my case it was file Eng_PCC2003_011.zip - ASUS WL-110 CF Card Driver, Utility and Utility release note for The WinCE 4.0 & Pocket PC 2003, English Version ). After you install them on your PDA, we put Wi-Fi adapter and a pop-up window «Unrecognized or somthing card windows» is entered «PRISMNDS». Note that the utility that comes bundled with the drivers to work on your PDA probably will not, therefore, to verify the functionality necessary to use alternative software, discussed further below, or use the default network configuration utility in Windows. The method described above "substitute" drivers, as the practice has helped very many, including me. If you continue to have difficulties with finding and connecting, I can advise to go to the site of PocketPC Magazine Forums, where the problem is discussed since last year. The local regulars healthy grown expert in such matters, so that might help you. Thus, we assume that the problems with the installation, we decided, and now in our hands a PDA with current Wi-Fi adapter and working drivers. Theoretically, any additional programs you need for further work on the wireless network is not required, and the connection process should go through without a hitch. But this is only theoretically. Consider first the process of connecting to an ordinary wireless access point as it should be done according to the theory, and then the possible practical variations and ways to resolve the crisis.

Connect to access point

Part One. Customize

1. Install the adapter in the slot and make sure that it flashes the LED turned on. If not, click the stylus on the icon "Connect» (Connectivity) in the system tray (two directed in different directions arrows) and select "Enable» (Turn Wireless On). Council. Turn off Wi-Fi adapter when not in use. This wireless monsters truly insatiable in terms of electricity, so your batteries are unlikely to hold out half of their normal working hours. 2. Having joined, the adapter will begin to go through the neighborhood in search of a network or other wireless devices. If you see them it will give you a list with the query: what network to connect and what a way to connect with this use. If your device is already configured, then the meaning is connected automatically. If this is the first wireless output of your device, you must use the manual setting. In this case, click "Hide» (Hide). 3.To manually configure your connection, click the stylus on the icon "Connect» (Connectivity) and select "Settings» (Settings). Click the Advanced tab »(Advanced) -« Network Card »(Network Card) - tab" Wireless »(Wireless). In the "Wireless Networks" displayed the names available for connecting networks. With the item "Add new connection» (Add New Settings) you can set up a direct connection with other wireless devices. About this way of creating a connection, read on. At the bottom, the drop-down menu for web access »(Networks to access), you can choose the type of networks with which you want to work:" All available »(All Available) - This item is recommended to choose" Only the access point " (Only access points) and "only computer to computer» (Only computer-to-computer). The latter type of connection used to connect to other wireless devices directly, bypassing the access point. Be sure to check the bottom check "Automatically connect to is not preferred networks» (Automatically connect to non-preferred networks). It is necessary to display information about all available for you to connect networks, not just those connections that have already been configured. 4. If you are within "sight" access points, then in the "Wireless" is displayed the name. Click the stylus on the name of the network, a window configuration. In it you select "Connect» (Connect to) with the «Work». Council. Use the connection «The Internet» just in case you go into the network through virtual private network (VPN). In all other cases, enabled only «Work». Since this paragraph is mine, probably the biggest mistake. We have to work we go out to the Internet, as many users through a proxy-server. Recently, we have an access point, also connected to the network. Every time I tried to connect my HP h2210 wireless network, of course, to wander through the wilds Internet, I'm on the simplicity of his heart, chose the connection «The Internet». The obvious choice, agree. What was my surprise when, promuchavshis few days, I found that to connect to the world wide web in any case not necessary to press on «The Internet», because only when connecting to the «Work» become available to configure proxy-server. 5. Go to the tab "Authentication» (Authentication), and then configure the network identification in accordance with established on your access point. So you should do only if access to the Access Point itself and its settings, you do not have. If everything is just listed you have, and point, for example, is at home or with friends, then configure it first: set up an automatic distribution of IP addresses, ie, Enable DHCP server and be sure to disable all kinds of protection, including encryption, WEP! Be aware that WEP is a basic way to protect and identify the Wi-Fi networks, since their introduction. Encryption can be, for example, 64, 128, 256-bit.Only when you'll get a normal connection with the access point and completely finished with the settings of the CPC, and only then switch on the cryptographic access point. In this case you need the PDA to establish a tick "data encryption" and enter "Network Key". Note that the network key is usually given in hexadecimal, that is, if enabled 64-bit encryption, it is 10 digits, for example, - «12345ABCDE». Regarding stability to cracking WEP, we rely on it should not. It has long programs exist that allow this defense around. Having dealt with the access point, do not forget to set the appropriate parameters and on the PDA. If you have disabled WEP on the network, then unplug it and on the PDA. Tick ​​"authentication" and tab "802.1x" and must be removed. 7. In this direction, perhaps, everything. We press "OK" in the upper right corner. Network Configuration is completed. We pass on the tab "Network Adapters» (Network Card) and select your wireless network card. In my case, the drivers from ASUS, it appears as Intersil PRISM Wireless LAN PC Card. Top choose "My network card connects to:» (My network card connects to:) «Work». When you click the stylus on the map opens a window enter the IP address. If you have a fixed IP, then select specific IP-address »(Use specific IP address), in emerging fields, enter the self address, subnet mask and default gateway. If the access point enabled auto-distribution of IP addresses, ie, DHCP server, preferably, just select «IP address assigned to server» (Use server assigned IP address). 8. Go to the next tab, "Name Servers» (Name Servers) and, if necessary, enter the addresses of DNS servers and WINS. Council. Which of the addresses to enter, and which is left blank, often quite independently determine fairly simple. Enough to the access point was connected to the same network as your computer. This is - a fairly common situation. For example, when you deploy a wireless network at home, or she has appeared in your office. In this case, type in the CCP are the same DNS address and WINS, both on the desktop. They are, incidentally, may remain unfilled altogether. 9. Press the OK button in the upper right corner, while you will be issued a warning: "The next time an adapter will apply the new settings. If you are currently adapter is installed in the PDA, remove and reinsert the changes to take effect." Follow this advice makes sense only if you have something really changed in the settings. 10.The last thing left to do to establish a connection is set up a proxy-server (unless, of course, you have it:). Click the stylus on the icon "Connect» (Connectivity) and select "Customize» (Settings). We pass on the tab "Tasks» (Tasks) and section «My Work Network» choose "Change proxy settings» (Edit my proxy server). In the window that opens, set the checkbox "This network connects to the Internet» (This network connects to the Internet) and "This network connects to the Internet through a proxy server» (This network uses a proxy server to connect to the Internet). Go to "Advanced» (Advanced) and set the IP address and port number. This completes the setting.

Part Two. Connection

We assume that all the settings you have made. But even if it is not, it is still at "Connecting» (Connectivity) - «Set» (Settings) - «Advanced» (Advanced) - «Network Card» (Network Card) - «Wireless» (Wireless) you you should see a list of available networks, with comments on the availability or unavailability of the connection. Typically, the network is not available if the access point is off. In other cases, it is available. This, in turn, does not mean that you can connect to it. Now gently presses the stylus on the name of interest to us online and in the dropdown menu, select "Connect» (Connect). It seems that all ... A moment later the icon left of the network will be circled in blue circle, and next to the name will comment - "Connected". Uraaaaa! Earned! Launch Internet Explorer and enjoy wireless surfing. You can walk to the access point, of course, if you have the administrator password, and to see the connection settings and login.

Nothing happens-I-I!

What are you talking about? Nothing is working? - Ah-ah-ah ... Well, okay. You will not believe, but all my friends, first tried to set up a wireless Wi-Fi connection to a PDA or laptop, it came out not that the second time, but, rather, from the fifth, and even the tenth.So it's not without fanaticism:) It is ironic, but the intuition on which all rely on when faced with 802.11b, in fact, does not help. You seem to be doing everything right, but nothing comes out. Several of these "wonderful" things we look at further.

Wait for an answer ...

One of the "wonderful" features work with Wi-Fi, I faced, relying on his intuition was (you would not believe!) - Slowness in establishing a connection, at least on my PDA. In a network where the data rate of 11 Mbit / sec, my PDA can register and establish a connection for half a minute or more. Of course, I did not know about it, so after waiting for 5-10 seconds and, without seeing the promised "Connected", immediately rushed to recheck the settings. Therefore let me advice. If you are not immediately connected, do not rush to change the settings, wait for at least 30-40 seconds. Perhaps it still happens. With my numerous unsuccessful attempts to connect to different wireless networks I was faced with two, I think, the general cases. In the first, a comment that is connected, without any notification back to the starting position, ie, the right of the network will return to the "available". In this case, you can try again to connect to the network, but it is better to go to revalidate all the settings. And carefully, comrades, look! Re-enter the WEP key if encryption is enabled, check whether the specified connection everywhere «Work», etc. I noticed that some of the checkboxes in the settings tend to appear and disappear on their own, especially after the power is turned off, so be on the alert! Note. You nothing says the phrase MAC address? - No, but in vain. After all, for it identifies you to the access point. Protecting the MAC address - the second after the WEP - a popular way to protect wireless networks from unauthorized access. Maybe on your access point is also included filtering MAS'ov, be sure to consult your system administrator and make your list of allowed MAC addresses. However, just like WEP, protect the MAC slightly resistant to the persistent "attention" outsiders. Council. To re-set is guaranteed to take effect, pull a few seconds the adapter from the PDA and install it again. After that, try to reconnect.

Well, where's my IP?

In the second case, when I could not connect, I receive an error message assigning IP addresses. Something like this: If the choice of two "evils" smaller, it is in some sense, more curable error than those described above. At least, it means that when connected to the CCP came to the last stage of the compound - an IP address. This failure can happen again for two reasons. First. Banal. When the access point is not enabled the dynamic distribution of IP addresses, but on the handheld - is included. Second. C that I have encountered much more frequently and it is, I think, in the following. Access point, for some reason believes that IP address already assigned to me and does not allocate it again. Basically this error when I reconnect to the network. That is, I was connected, a time is active, then either the PDA switched off, or I'll disable it. When you switch on and try to connect to network my h2210 is just to give an error getting IP. In fact, as I found out, it turned out that way. And log files Access Point is once again confirmed it. Therefore, please note the following information. Note. Assigned to you when you first log into the network a dynamic IP address remains fixed for some time for your PDA (the time setup in the access point) - more precisely, for its MAC address.If you turn off your PDA, your IP address in the memory is not saved. The next time you connect the access point remembers the IP address it has already betrayed you, and possibly re you do not get it. Uniquely solve this problem I could not. So, in my opinion, better than you initially try to avoid it, ie, connecting to work or wait until the last with repeated access to the network until the point of you "will not forget." Retention time of assigned IP addresses on the Access Point, which I came across, by default it is 1 hour. If this is not an option for you, then you perfect a wonderful program PocketWINc, which helped me in all settings, find and solve problems, including this one. Again, note. Remember at the beginning of this article, I talked about how nice to have a built-in Wi-Fi module. Most of the problems described here, including reacquire IP, are, apparently, the result is broken on my HP h2210 drivers and software, and it is not apparent, for example, HP h4150 with a set "native" software and a built-in . This handheld, owned by my colleague at work, lying at 10 centimeters from mine. He is "no nails" from the first time connected to the network, obtain an IP address, while my machine, the hard "puffing" and all the lights blinking, tried unsuccessfully to reach the Access Point, which did not want to admit it.

Weapons of this Wi-fayschika

I tried several programs to facilitate the work with wireless networks and simplifying the connection process. Equal in convenience and functionality PocketWINc 1.3 (shareware) I have never met. Highly recommend! Functions and tools from PocketWINc quite a lot, but I'll talk about those that I really come in handy. Actually, this program is not needed at all if you are all well and works without problems. What I liked about the application. Firstly, it is very informative main screen, which displays the available network and connection status to them. For example, depending on the type of icons before the name of the network, you can immediately see that at a particular point is: the network is available or not available, you trying to connect to it, established a relationship (Associated), and finally - whether you are connected. If successful, The compound icon turns green. Since one of the biggest problems was for me the task of obtaining IP addresses, among other things, re-obtaining, my most used tools are in the menu Tools (see list in the screenshot). I'll tell you about each of them in detail. - «View IP properties ...» - the first in the list, offers a view of all your settings on a network: adapter name, MAC address, DHCP server, IP, subnet mask and gateway, and others. - «Ping ...» - command «Ping» similar to the desktop on Windows. It will be so helpful to test access to Access Point and to other computers on the wireless and wired networks. - «Release IP Address ...» - ideally this command returns the IP address. - «Renew IP Address ...» - ideally a team request a new IP address. Why is it only "ideally"? The fact is that with these two teams without a problem would be to solve the problem of re-obtain its IP address. That is, first, we return the old access point IP - «Release IP Address ...», and the following command «Renew IP Address ...» ask a new one. Unfortunately, I have such an approach has not worked. But then passed version of the mixed and completely pointless, that is, not having a specific algorithm. I randomly went through the menu command «Release IP Address ...», «Renew IP Address ...», and also by pushing the stylus on the network name, chose the «Connect» or «Connect & check Internet». The method of "engineering spear" breakdowns usually within 5 minutes and the compound appeared. PocketWINc helps me in many situations. It happens that the standard way to connect is not working quite correctly. That is next to the network may be a comment - "Connected", but in fact connection had not occurred. Here then again rescues weapons present Wai fayschika, for example, a red icon next to the network announcing that only a connection with a point, but no connection. Go to the menu item «View IP properties ...» - and really, IP is not obtained from the server, but instead used some strange internal address. It's all clear. IP was not given to us, you must request it by hand «Renew IP Address ...» or perform re-connection.

Once more on the software

I spent a little searching on the program directory for the PDA, enabled us to discover a few more applications that would be a nice addition when working with 802.11 b. Moreover, two of them - are completely free from them and begin. WiFi Graph - a nice program to view information about being in proximity to hot spots and the signal strength from them. It is with this small program I was running around the office, looking for places where Wi-Fi «finishes, but where - no. WiFi Graph is useful also if you select the optimal location for the Access Point. Distribution Type - Freeware. WiFiFoFum 0.3.1 - utility-radar. Similarly to the previous program, it finds the nearby access points and displays information about them and the signal level on a round screen, a la the radar. A second useful feature of the program is to determine (albeit roughly) the direction of a specific access point. Distribution Type - Freeware. Net @ Board 1.0 - this softina, which is conveniently located on the screen Today, provides you with quick access to desired settings of the wireless network. In terms of functionality, it approaches PocketWINc.You will have the following options: information about the found networks, data on the amount of wireless traffic, information about your IP, the possibility of "ping" the neighbors, to execute the «Release IP Address» and «Renew IP Address», as well as quick access to standard windows configure the network adapter and connect. Distribution Type - Shareware.

Asya aunt did not come ...

To my great regret, I failed to make any ICQ, none of the programs operate in analog wireless option to connect to the Internet. Connection in any case not be made. All this outrage took place against a completely trouble-free Internet surfing. List of subjects was as follows: ICQ v1.0b, imov Messenger 1.15, Agile Messenger. My negative experience, in this case is rather an exception and did not specifically mean. Perhaps it is you Messanger work. I sincerely wish you that. If not difficult to share with me a positive experience at the end of the article:)

Online Resources

Wireless network, as, indeed, common - is not limited to surfing the Internet. Any network - it is also a diverse gathering of information on others computers. Get to "share drives" resources in two ways - a convenient and standard. Easy way - is to use the program Resco Explorer (Shareware). To search for available network resources, simply press and hold the stylus directory «My Network», the pop-up menu, select «Map Drive». After a while you will see a list of available network drives. A second useful tool that provides you with Resco Explorer, will access ftp resources. Create a new session and connect to the servers. Awkward way (read - "standard conditions") - is to use standard means of Windows - «Explorer. Run the program and choose the menu "View" in the dialog that appears, type the network path, for example, «\ \ comp1 \ Common». What this method is inconvenient, to explain, I think, is not required.

Direct connection to computer-computer "

Briefly describe the process of setting up a direct connection PC and PDA, has been repeatedly tested and almost 100% efficiency.

So, first configure a desktop OS (Windows XP):
1. Connect Wi-Fi adapter into your PC and install drivers for it.
2. Go to "Control Panel" tab "Network Connections". If the adapter and the drivers will install correctly, there will be an icon "Wireless Network Connection".
3. Right-click on the "Wireless Network Connection" and select "Enable".
4. Right-click on the "Wireless Network Connection and select Properties.
5. On the General tab, select Internet Protocol (TCP / IP) »and click the Properties button.
6. In the resulting window, select the option "Use the following IP - Address" and in the «IP-address" type «192.168.2.2», in the "Subnet Mask» - «255.255.255.0» and click "OK".
7. Back in the Box "Wireless Network Connection" - "Properties", go to the tab "Wireless Networks".
8. On the tab "Wireless Networks" click on the Advanced button.
9. In the "Advanced" choose "Network computer - just a computer, install a check" Automatically connect to network "and click" Close "button.
10. On the tab "Wireless Networks" in the "Preferred networks" click on "Add" button.
11. In the window "Wireless Network Properties" in the "Network Name» (SSID) enter an arbitrary network name (it is then necessary to enter and PDAs).
12. Remove the check mark from the field "Data encryption (WEP)», «Network Authentication" and click "OK".
13. Back in the Box "Wireless Network Connection" - "Properties" and click "OK".

Verify and monitor the status of the connection by using icons "Connection", which should appear in the system tray.Clicking on it, you can see the status of your connection and signal strength.

Now the settings for PDAs:
1. As usual, install drivers and include Wi-Fi adapter.
2. Click the stylus on the icon "Connect" and select "Configure". Click the Advanced tab - "Network Card" - tab "Wireless" - "Add new connection" - enter the network name (same as on a PC), select the connection type «Work», and set "Connect a computer to computer" (AD-HOS).
3. Under the tab "Wireless" - menu "Networks to access" select "Only computer-to-computer and install check" Automatically connect to the network is not preferred. "
4. Under "Authentication" clears all checkboxes.
5. Under "Network Adapters" select your wireless network card and connection type "My network card connects to a» - «Work».
6. Click on the network card, choose "A specific IP-address" and enter the IP-address «192.168.2.1», subnet mask «255.255.255.0» and default gateway «192.168.2.2».

That's all. In the "Wireless Networks", you should have a name for your connection. Click on it with stylus, and select "Connect". Problems should arise. To test the connection to a PC from a command prompt (Start - Run) run «ping 192.168.2.1». Using PocketWINc, run «ping 192.168.2.2». If packets are passed, then the connection is established. Start the Resco Explorer and use your desktop PC. In case of difficulties with the connection, you probably just made a mistake with the settings. Now, it seems everything:) Uffffffff ...

Total

No matter how complex it may seem a large number of settings, the subtleties and nuances of working with Wi-Fi, in fact, spending a little time and deal with technology, you can get is extremely handy tool for wireless in the first place, surfing, significantly increases your mobility and clearly talking about your advancement in the eyes of others. I wish you success in the conquest of the wireless internet:)

Wi-Fi points in Moscow and St. Petersburg

Specially for those who have reached the end of the article - a bonus - a list of Wi-Fi cpotov (free and paid), located in Moscow and St.-Petersburg. The authors, translation:

Familiar Stranger - Intermec Model 70

First a few words about the model. Intermec Model 70 - a compact device that is running Windows CE. Thickness is not more than six inches, and weighs less than 170 grams. The model is equipped with a StrongARM processor from Intel with a clock speed of 206MHz, as well as the Compaq iPAQ, and therefore provides the possibility of a similar level. Despite the apparent harmony of design, the Model 70 is built-in memory expansion slot CompactFlash. Screen at Intermec Model 70 monochrome and is capable of showing 16 shades of gray. True, it is somewhat surprising in our era when all devices are trying to equip color screens. But the image in the open air clear and sharp, and this is a big plus. Intermec Model 70 - well-cut and sewn PDA. The only negative is that the plastic casing and the screen is left unprotected. So with the acquisition of protective cheholchika he ceases to exist. So where does appear this new Pocket PC on the market in which and without stiff competition reigns. Even for experienced writers magazine Pen Computing its existence was a revelation. This PDA demonstrated the general public at Mobile Insights Conference 2001, which was recently held in Phoenix, Arizona. The overall design of Model 70 resembles Philips Nino, and the buttons on the front panel seems to have been borrowed from the earlier models Evervex. It also has something of kicked the bucket Compaq Aero 1550 Pocket PC. His informal presentation was accompanied by the phrase: Made by ITC (Intermec Technologies Corp.). That is what explains the fact that this model has been a mystery to most. The fact that the ITC - a Taiwanese company, whose products rarely goes beyond the Asian market. So what made Intermec to provide such a device as the Model 70. The answer is simple, as all ingenious. Just the company has realized that consumers want their products cheap, easy to use PDAs in the field, trailers, etc. Consumers interested in purchasing products from companies that he knows and which he trusts. A company, in turn, is interested in maintaining their clientele. Model 70 in this situation - the ideal way out for those and for others. Unlike Casio EG-80/800 and Casio IT-70/700, Model 70 can be a standard model in the consumer market Pocket PC. Its dimensions 7.9h13h1.27sm and weighs slightly less than 170 g. It is thinner and lighter than other comparable models and is suitable for use in any setting. Looking into the depths of gray plastic shell can tell you about, as if the next generation might look like Compaq Aero 1550. In other words, with some justification, that Model 70 could be a new monochrome PDA, offered by Compaq. The design and layout of the motherboard Model 70 is almost identical to the old one Aero 1500. Battery, CF slot, the connection with stand and other components are located in these devices are also similar. There were, however, without some rearrangement, to a simpler assembly. So, for example, has changed the location of the battery and speakers. As with the devices Compaq, the new PDA is a subsidiary board Intel Flash ROM chip that makes it easy to upgrade the device. As acknowledged by professionals, the company ITC brilliantly managed not only to use an existing design concept, but even improve it. Especially conspicuous difference from the 70-ki Aero 1550 is that the latter worked on the CPU 70MHz NEC VR4111 CPU. Model 70, in turn, feeds the forces of the 206MHz Intel StrongARM SA-1110, as the iPAQ, opportunely. And because the speed he has is three times greater than that of Aero 1550, so its capabilities can be compared to the iPAQ 3650. As a result of comparative tests revealed that Model 70 - one of the fastest PDA.Speaking of ergonomics of the device, we can say that the Model 70 and here at altitude. With its elegant design, the pickpocket does not create the feeling, as if in his pocket is a heavy brick. A few bent Nino-like shape of the device allows easy and convenient to place the device in the palm. Unlike the iPAQ and HP Jornada 540, traditional rocker and action buttons are located on the left side of the pickpocket, and the front panel accommodates five buttons application. Four of them are like the leaf clovers and comply with the following applications: Tasks (Tasks), Contacts (Contact), Notes (Notepad) and Calendar (Diary). The fifth is a button code-named Windows. It was she who brings up a menu Start (Start). It is interesting that include 70-ku in two ways - either buttons on the left panel, or the yellow button on the front panel. The same yellow a button turns on and off the screen backlight. The big plus of this device, unlike the iPAQ is the availability of expansion slots CompactFlash. This means that the user does not have to acquire an additional optional module to connect the CF Card modem, Ethernet adapter or card for storing information. True, it is not necessary to experiment and try to connect to a slot IBM MicroDrive or Type II CF card. Model 70, as well as the HP Jornada, only supports standard CF card. The connection and synchronize with your desktop computer or laptop can be done via the IR port, which is located in the upper right corner of the device, or through the cradle. By itself, stand like a cradle Compaq 1550 (by the way, he enters the cradle Model 70). Its design is made at a decent level, and Model 70 "feels" himself in the cradle as well as possible, ensuring a good bond. In the described device, the connection with your desktop computer through a serial port, however, there is a USB-version of the stand. Powered Intermec Model 70 from 70mAch yonnogo lithium battery. Note that, presumably, Aero 1550 was supposed to operate without recharging for 14 hours on a 600mAh battery pack. In reality, rarely to squeeze more than six hours of battery life 950mAch color iPAQ. Approximate time of Model 70 is about ten hours. Now a bit about the screen. Once the user gets used to the absence of color, he is aware of sharpness and clarity. It is quite decent as indoors and outdoors. The only thing that the contrast is not as high as that of the leading black-and-white counterparts. For example, the Palm V, we see an image of black text on a light green background. In Model 70 is more of a dark green text on a light green background. Summarizing all the above, we note that Intrmec Model 1970 Pocket PC - fast, convenient and affordable Pocket PC, which will be of interest not only to existing customers Intermec, but those looking for fast monochrome PDA.

Enmeshed in a "blue network&quot

The subject of this research - opportunities for the organization of personal wireless Bluetooth-based network computer with an adapter Bluetooth USB - Billionton USBBTC1A. In this article we will test the connection to a PC with mobile phones and handheld computers using a wireless connection. Of course, all mobile devices that participate in the experience, support Bluetooth. To get started all a bit will tell you about the virtues of personal Bluetooth-networks in relation to our little experiment in which, again, involved a desktop computer, mobile phone and Pocket PC, networked with "golubozubogo" USB adapter. So, combining the desktop to the cellular handset wirelessly, you can afford a lot - to throw the contacts stored in the mobile phone on the big PC or even, for example, popolzovavshis "ICQ" to work where you are in addition connected to the LAN desktop, there is a stern administrator , the ban on all kinds of internet pagers. In the latter case will the following scheme. Authorized service continues to use over a network connection, and configure ICQ to work through their cell phones. In addition, the use of Bluetooth-bundles "PC + mobile phone" is obvious if we do not have my phone jack and modem. As for the unification of Bluetooth-channel handheld computer and its desktop counterpart, here again the mass of applications - from wireless synchronization of data stored on PDAs to surf the Internet or LAN through a big computer. However, in the latter case, you are somewhat limited area of ​​Bluetooth - the order of 10 meters, but still nice. Now, Own, about the main thing being tested - USB adapter for a large computer.

Here are its features:
• Class 1 - the radius of 100 m (applies to that radius only if the reply device supports such a distance). Class 2 - 10 m

Specifications:
• Bluetooth v1.1
• USB 1.1 port
• Compatibility - Windows 98/2000/ME/XP.

Detailed list of parameters Bluetooth USB adapter, you'll find in this plate. Included with this device comes with software CD, installation guide, extension at 50 cm USB / USB. Begin, as well as advising management, with the installation of the software (driver and application software) from the disk. Prior to the installation software did not connect the adapter is better, though do not worry if it is connected in advance, will not happen. The system itself will search the USB drivers, and only need to abandon its proposal. So, install software. There are no deviations from the standard process. After the download is complete on the computer, the following changes. At the bottom of the toolbar icon appears in Bluetooth. This icon will be red until the adapter is connected and becomes green when we finally connected to the USB port. On the desktop, as well as in the "My Computer" icon appears My Bluetooth Places, which should push to open the main setup menu. We begin to configure the device by clicking the icon Bluetooth Setup Wizard. The main thing - to choose and configure the options that we need in the future. On the order of each of them: - PIM Item Transfer / PIM Synchronization Responsible for file transfer and synchronization of personal database (for example, Microsoft Outlook) c of such a base and a business card and other devices. It is not clear yet, it is useful to us or not, because when working with the Pocket PC for these purposes will be used by specialized application (ActiveSync for Pocket PC). However, in our experience will participate and a mobile phone, so put a check and set up to synchronize with Microsoft Outlook. - File Transfer Sharing files between devices. This option makes sense to connect and define the folder where you will be sharing files. - Network Access Access to the network will allow access to network resources of a computer (eg Internet access) to mobile devices via Bluetooth-connection. Since our big computer is connected to a network, you may be able to somehow use this resource. Pocemu assign configuration settings - Allow access to the internet through this computer ". - Dial-up Networking Ability to set a bunch of: a mobile device - "a big computer (via Bluetooth-connection) -> Internet (via a modem connected to a large computer). Since we do not have a modem, then test this original way, we will not.- Bluetooth Serial Port But this possibility, we need one. It is through this virtual port will be an interaction Pocket PC via ActiveSync c big computer. When configuring the system suggests us to use the port COM7 (on other machines can be offered to other ports depending on which of them are free). - Audio Gateway possibility of using Bluetooth-headphones. Headphones have not yet, but the plug and this feature - a sudden end of the study that will change for the better:) - Headset And this facility allows you to use a microphone and speaker of the computer instead of the relevant attributes of a mobile phone or any other device, which we try to connect. In other words, the computer becomes a big earphones. Connect and this chip. From the unencumbered leaves us with only the "Fax", which certainly will not activate. Now we are ready to open the Bluetooth-Ups between different devices.

Experience first, or the connection of a large computer with a mobile phone

We have a little outdated but reliable tube Ericsson T68. First of all, maximally briefly about how to enable Bluetooth in the mobile phone. In the "Connections" (Sonnect), in line Bluetooth, select the Operation Mode and translate mode to ON. Then on the desktop in a row Discoverable includes options to find a mobile phone. This mode runs for 3 minutes, so you immediately start the procedure by using the menu Find Bluetooth Devices. Our T68 remarkably quickly discovered a big brother, so that count - half the job done. Now it is necessary to conduct the process of "pairing" (pairing) devices, that is, give them the opportunity to get to know each other, share passwords. Dating procedure is performed only once, so that in future the device when trying to connect immediately "recognize" each other and start working together without formality. (Note: you can set up communication so that each time a connection between the devices will be prompted for a password). Right click on the icon in your phone and select Pair Device. The pairing process went. On the computer screen in the bottom menu appears Bluetooth PIN Code Required. Introduce an arbitrary number and a similar message is already on the small screen phone. Introduce the same number and familiarity completed. Phone icon on the top left there is a check mark, indicating that the pairing process was successful and can be ready for the next experiments. Go ahead. Click on the icon of the phone and go to the following menu: There is a set of icons, but we are interested only connection Dial-up Networking. Click on the Dial-up Networking: On your computer, there is a window "Connect to Bluetooth Connection». Here you need to type a user name and password, depending on whether, to what cell phone is connected to the operator. ... And now the connection is established. Here you need to make a brief remark. We assume that our phone is connected to the network GPRS. Information on how you can do it you will find on the sites or carriers to HPCru. In our case - in rows "User" and "Password" enter the mts, in the row "Type" - * 99 #. The latter depends on phone model - see the relevant information about your phone on the operator's website. The speed of connection in the GPRS may be different, in our case, it reached 115 Kbit / c, which is quite decent. As you can see, the icon has a green phone. This means a working connection. That's all for this step. You can now use cell phone as a modem and to check out the Internet. On the big computer in the Internet Explorer settings, select "Tools" -> "Internet Options" -> "Connect". Click on "The compound via Bluetooth". In the second test Let us install a Bluetooth connection between a large computer and handheld Pocket PC.

Experience of the second, or the connection of a large computer with a pocket

In general, everything as well as a mobile phone. First of all, activate a Bluetooth mode on Pocket PC. If you have a HP iPAQ, then all is simple. Turn radiorezhim, start the Bluetooth Manager and launch the "Search" (Search). Choose the device to synchronize and be sure to put a tick in the box ActiveSync Partner. And that's all. Cparivat device, of course, is not required. At this stop, we will leave until the iPAQ alone and look so simple it's all done on other devices. It turned out that when working with the Pocket PC without a built-in Bluetooth (where as radioadaptera uses CompactFlash card or SD), the situation is different. We experimented with promyshlennnym pickpocket Symbol PDT 8000 and card Anycom Bluetooth CompactFlash Card. So this bunch steadfastly resisted all attempts to establish a connection (by the way, in this case do not dispense with the procedure of pairing) and earned only after a few reboots of both machines. Below are screenshots mikrokommentariyami showing the sequence of connection in this case 1. Initiating a connection c screen PocketPC 2. Found a Symbol 8000 c Anycom Bluetooth. T68 handset is in the pocket. Pay no attention to nowhere invading notebook LAWGROUP (in our office do not exist, apparently the owner in an adjacent room). 3. The process of mating, the authorization is required. 4. Enter the password (and then the same on Pocket PC) 5. All right, the icon appeared checked, you can now connect. Now the iPAQ, Symbol, and are ready to further hostilities, which are the same for both devices. We continued to experiment with Symbol, so the icons on the following screenshots will simbolovskimi. So, what to do next? Next you need to prepare ActiveSync on both machines. Since our earlier work with Pocket PC AstiveSync through the physical port (serial or USB), but now we need to change the port because the Bluetooth connection uses in its work to a virtual port. How do you know what this port? Port we have automatically established at the very beginning of the article, when we installed the drivers for the adapter. Go to My Bluetooth Places -> My Device -> and see the following picture: Remember the port that corresponds to the line My Bluetooth Serial Port - we have it COM7 (not necessarily that you will have the same description of the potential problems of looking at the end of the article).On the desktop computer run ActiveSync -> File -> Connection Settings and select the port COM7 (he must be on the list of ports, but there may be exceptions, again - about this at the end of the article). If the iPAQ on this for almost everything, then Symbol still need to configure ActiveSync on the device itself. Why in the start menu, click ActiveSync, and select the appropriate port (in my case BTActiveSync (COM6), do not be alarmed that the port is different from the port on a desktop computer, it's as different machines). And now, after all the ordeals in the Start menu, click on the BT ActiveSync and install ActiveSync ... coedinenie! Now you can enjoy all the benefits provided by ActiveSync (email, other opportunities Outlook, transfer files, etc.) at a distance of 10-15 meters because of a computer. And now, as promised, a few words about the problems that, despite all the carefully and consistently carried out the procedure may still occur. Sometimes (and not so rare) that the compound, despite the fact that everything was done correctly, still does not want to install. Bluetooth developers in such cases has been criticized generally for Microsoft ActiveSync (quote: "it happens that ActiveSync for some unknown reasons, switched to a strange situation in which some unknown reason the connection is impossible"). Microsoft has a different point of view on these issues, because we all know that Bluetooth is yet still somewhat damp (more on this issue can be found at www.cewindows.net). But what if we do get into this situation?

The first tips are:
1. restart both computers. If not helped, then Look at the following paragraph.
2. reconfigure all the ports back in and carry out the procedure ActiveSync ordinary physical means. Then again to reconfigure the ports under the Bluetooth. And if it did not help, then www.cewindows.net described a problem that, who knows, may prevent you, too. About it - just below.

There are situations when your computer employs a large number of virtual ports for all different peripherals. So, when you install the drivers for the Bluetooth adapter, the program selects the first free port, and if you are busy all the ports to COM9, respec-tively it configures itself by COM10. No error messages or some program does not give warnings (yes, because any mistakes and was not). And the problem is that ActiveSync (in any case before version 3.5) does not support ports over COM9. In order for this fix, you must uninstall the program, kill all unnecessary ports and re-installlirovat software to produce the desired port. We hope that this little manual will serve as a model for organizing personal "golubozuboy" network. Good luck to you and comfortable existence within it of:) The authors, translation:

Computer in the ear

At the mention of wearable computers in our imagination arise device on the strap, worn on the arm, battery, tacked on to his belt and placed in glasses displays. An integral part of these kits are cords that make a person look like a walking network. So look the computers that we carry. However, in the future, perhaps there will be other - built in what we wear. Researchers from IBM's labs have started creating device projects, whether in the jewelry worn by us daily. Expected to create a wireless personal area network (PAN), comprising a device that will let into watches, bracelets, earrings, necklaces, rings and other jewelry worn on different parts of the body. Imagine the speakers, set in earrings and a microphone hidden in the fob attached to the ring. Actually the computer and the display will be built in all wrist watch or a bracelet. Blocks will be linked with technology similar to Bluetooth, through the tiny low-power high-frequency devices. Communicate through this network will be possible only within a radius of not more than 1 - 2 meters. If the current Pocket PCs are designed primarily to assist a person in work and business, then the wearable devices of the future is assumed different purpose: they will focus primarily on user privacy. Of course, receiving a reminder of the upcoming meeting, or receive a message from a business partner by e-mail - it important. Everyone wants to also keep in order your calendar and address book. However, this is not the services a computer in which a person needs in daily life. Applied systems oriented to privacy, will perform tasks such as voice communication, obtaining information on the whereabouts of the user, as well as provide entertainment. According to technical director of IBM's Michael Karasik, built-in jewelry worn device, most likely will not need the Start button, and, possibly, in the display. Supporting infrastructure, providing job application systems will only need to activate the device permanently in standby. Let's look at some examples of wearable computers in everyday life. The family spends a vacation at the resort. With a device installed at each of the bracelet, watch fob, or parents will be able to determine where their children, and even tell them where to meet for breakfast, lunch or dinner. Or another example: when you play golf wearable computer calculates and displays the distance from the ball to the hole. He may even be able to indicate playing, what a club it is best to take, given the strength of its impact and possible obstacles. Both these situations are among those where the user is not very willing to receive any alert signals or read the messages that came from the staff via email. It is extremely important in everyday life the scope of mobile devices is to determine the location. Imagine that while traveling, you are using a wearable computer figure out where the nearest restaurant that serves your favorite dishes. Perform such a task can and PDAs, but more effective would be an automatic transfer of information through a device incorporated in the decoration: it ensures that person is free from having to remove the PDA from a pocket or handbag.Handheld devices can also be used to provide various services in the business when to use a cell phone, pager or PDA inconvenient. In such situations, flicker your rings and a short buzzer can serve as a signal that tells them to answer the phone or get an email. A quick glance at the display, a built-in clock or a bracelet - that's all you'll need to get the warning. If you're in this business meeting, nothing will disturb and will not irritate sitting next to you people. Here it would be appropriate to ask, Is it even possible embedded portable device? I must say that even now there are some parts needed to create them, such as mini-chips for global positioning system GPS, as well as the small batteries used in microphones. Among the organic components of display (OLED) can be cheap to create screens that require no backlighting and high energy costs. At the IBM Watson Research has already been demonstrated computer on Linux, installed in a wristwatch. When you create a jewelry set with embedded computers will be taken into account the need to use multiple batteries. Consume additional energy, coming out of standby mode, will not all but only those devices that are needed at the moment for a specific application task. IBM has built into the ring device working on the technology Trackpoint, and now the menu on the display (presumably it will be installed in a watch, bracelet or glasses) can be deployed either optical or a few clicks. Built-in sunglasses displays, through which the user can, for example, view news headlines, will probably part sets autonomous wearable devices. LCD screen with a diagonal of just 0.3 inches can be used for projection on the inner surface of the lens. In the future, can be installed in glasses and a device manufacturing and forming an image that will allow the user of portable computer to recognize and distinguish the surrounding objects and people. In small blocks of wearable computers of new generation will be "sewn up" the mass of different technological innovations. Maybe, especially for embedded devices in the jewelry will be developed operating system WRIST (Wearable Real-time Information System Technology or technology information systems for real-time portable devices). However, as the scholar said of the company's Almaden Research Center IBM Cameron Miner, "an even greater extent than the technology, the direction of the work on wearable computers will determine the mode."

PDA Buyer's Guide, April 2005

In this article you'll find brief overviews of most PDAs and smartphones, presented at this time on Russian PDA market. For convenience, we divide the entire range of the following groups: the initial price level (see below), the average price level, hi-end and communicators (the phone is handheld). Meet, compare, choose. This material is updated monthly as new models of handheld computers, leaving the market obsolete and change the indicative prices. For ease of navigation through catalog images of some handhelds are equipped with special badges: Hit the month "," Super-Price "," Soon on the shelves! " and "on sale now, which we hope will help you sort out the variety of the world's handheld ...

The initial price level

It is paradoxical but true: In this section the most inexpensive and yet the most recent advances PDA-thought. The fact is that until very recently, handheld computers with these characteristics were not available to most of us because of the price dictated by the young market, and just because it did not exist. But over the past year of a miniature computer industry structure has made such a leap forward that the most distrustful left any doubt. "They know how" these devices are now smaller than desktop computers the mid 90-x (200-300 MHz processors), and cost (the most expensive model in the class) a little over $ 300. PDAs initial price level (or "low") are perfect for you if you first decided to purchase such a device. Firstly, they are - just a copy of their more expensive "brothers" - with only a little stripped-down processing power and functionality. Second, available to almost everyone. With their help, you will have the opportunity to meet with one or another handheld operating system, choose the most suitable, as well as a skill with a small computer. In addition, this handheld is always appropriate to give a friend or girlfriend, if he or she is certainly not zapravskie PDA users. Although, sure, and the last will be glad surprise: after all, a PDA is good, but two - better.
