Our life is full of paradoxes. I, for example, have all the time to describe the latest, most advanced models of cellular phones, although my heart belongs to old-fashioned and modest capabilities Ericsson A2628. He was so nice in your hand - not too big and not too small. Almost nothing special is able, but in terms of telephone communication - well done and clever. In short, I got used to it badly. But want something unusual. Around the same people. Namely - the young girl whose imagination can be hit or their outstanding articles, or any trifle expensive, pointing to the refined tastes of the owner and his financial well-being. A statistical fact is just missing (burgher stomach, for unknown reasons to me among young girls is not quoted), because it has to fend minim ... Let's talk about phones. More precisely - the unwinding with supersonic speed Bluetooth wireless technology with regard to mobile telephony. Bluetooth module integrated into phones latest models gives the usual "mobile phone" hitherto unseen possibilities. A plug adapter will pour new wine into old bottles - to breathe new content in the broken phone time, even in my budget "Eric", from which, frankly, it's time to get rid. But this is unlikely to happen any time soon. The excuse will bring a couple navyazshih platitudes - "horses in midstream is not me" and "an old friend is better than two new ones (although in fact need more money and do not cling to the old toys).
Hands, who fries, and something to say about this Exler
Bluetooth in the translation is called "Blue Tooth". Why tooth than he was at fault, if he called them gay, I do not know. However, the joy that the Russian, the Germans - death. Unusual for a combination of our ear (and only for some unusual language - that and look vyplyunesh him, trying to correctly pronounce a "th") in English, they say, sounds quite nice ... Name - a unique, something to be ironic. Everything else is very, very seriously. Before the grave that we can talk about a real revolution - both in the personal computer industry and the technology of cellular communications. Bluetooth - the wireless standard radio high frequency range of 2,4 - 2, 4835 GHz. Transmitter power is low - about 100 milliwatts. Maximum range - up to 100 meters (average 10 meters). Average exchange rate - about 720 kb / c plus or minus a certain number of kilobytes in the different implementations Bluetooth (maximum - about a half megabytes per second). In phones, Bluetooth adapters can perform different functions - from the arrangement based on these headsets covert, to the operational link with phone pocket and personal computers.

First, let's talk about headsets ... Device for conducting telephone conversations at a distance from the device without the need to bring a fairly powerful transmitter to his ear, certainly useful. Driving a car without a headset cell phone can even be dangerous, as distracting the driver from driving. The headset also keeps your hands free - so called handsfree. Structurally, the headset handsfree (another, less precise, but the Russian name - headset concealed carry, though admittedly not too hidden) is a miniature earphone (speaker) is worn or loose-leaf type (with or without a holder) with a fortified by him or on cable headset microphone. If a microphone is attached to the phone itself, as structural elements apply flexible or rigid bracket. If the microphone is mounted on a cable connection, its position is chosen so that the receiving part of the electret microphone is in close proximity to the user's lips. Technology headsets more than a hundred years (actually the same as most telephone service).It is curious that one of the most effective solutions - laringofon or microphone, fastened at the throat user - in mobile telephony is not applied at all. Firstly, laringofon easily attached only by a helmet (a tank or aircraft). Secondly, the tone of voice when using laringofona few changes (although this is unlikely to become the decisive reason for rejecting its use). Whatever it was, while the headset is one drawback - the wire that it connects to the telephone. Meanwhile, some phones, such as "youth communicator" Motorola V100, use the headset as the primary and only means of voice communication. In V100 simply has no built-in microphone or speaker. Must be content with only a headset ...

It Gets Worse? Why, in this wire ... If you never ever use your player walkman, trust me on word - connecting headphones and a tape (or disk based on flash memory) player posting thing is very inconvenient. Thin connecting cable entangled in clothing, and the sudden movement of the head pulls off with ear pads (especially in miniature their performance - in the form of loose-constructs). In the heat of the posting sticks. In the cold of a wooden ... No, it is inconvenient. It is for this reason, the Bluetooth headset is rapidly gaining popularity, although their cost may exceed wired counterpart in ten, twenty or more times. Benefits headsets Bluetooth, for example, the latest model produced by BTH 100A Acoustek Innovation Technology (Guess once - where he lives, this company ... right, in Taiwan), and yet that power high-frequency transceiver immeasurably less than the capacity of cellular transceiver phone. In this figure the headset almost a thousand times less than the phones (milliwatts against Watts). Hence, experimentally unconfirmed risk of cerebral high-frequency radio waves is reduced to zero ... "What I soar brains in a microwave oven?" - Said my friend Alex Exler. And I totally agree with this fun and talented person. But security is not all. The accurate transmission of acoustic signal from a Bluetooth headset on the order of magnitude higher than the wired headset. A digital interface. Convert the digital signal into an acoustic made directly to the adapter. Decreases the length of the conductors, eliminate any possible interference and crosstalk ... Not without reason Bluetooth modules have penetrated into another area of complex electronics - home to the world of musical instrument class Hi-Fi. Now, along with models of cordless phones that use ultrashort-wave radio band, and an infrared link, there were headphones Bluetooth. Presumably, these newcomers will soon supplant the market with their predecessors - with the highest quality sound transmission, long range, miniaturized and autonomous ... By the way - a Bluetooth headset can not do without power. In the aforementioned headset BTH 100A uses a miniature lithium-Ion battery, charging that the headset has a connector for an external unit. Of course, this does not add to ease of use headsets - wired device battery is not needed. But we also charges the battery of the phone and not grumble? Get used to the battery and the headset. The corpus BTH 100A (it resembles a flat cigar, elegant and easy, which is attached to the bow to put on the ear) is built-in microphone. As befits a high-quality headset, it provides full duplex communication - can simultaneously speak and listen (simplex communication used in radio CB - there to listen and speak in turn, operating power button transmission on the microphone). To purchase a wireless headset, a Bluetooth module is not equipping the phone itself, not the slightest sense that increases the cost of the solution ... But it is the most venial of all the possible shortcomings Bluetooth! God be with her, with this wonderful headset. I may never it did not use it. But the plug-in Bluetooth - a real miracle.With it, even my old man A2628 becomes spirited steed phone ... And what about phones with built-in modem?
Only with Bluetooth can grasp the immensity

These applications are difficult to consider separately ... The fact that the Bluetooth adapter integrates cell phone to any computer equipped with the same interface. That is literally integrates phone and computer in one. And, no matter what kind of computer - desktop, laptop or PDA. Bluetooth for all is one, he is extraordinarily intelligent and with all the difficulties to cope independently (if at the same time we will be able to cope with the provision of software support). The most common case - you have a cheap phone with a built-in modem and plug-in Bluetooth. And in the other pocket - Pocket PC (any model with a card slot) with a card Bluetooth. Actually, nothing else is required. If necessary, you can always rearrange the wireless communication module of the handheld computer into a laptop or desktop - through a card adapter ... But we are still interested in a PDA. With some regret (but not maliciously, come from the same tribe) is compelled to note that the system "phone + PDA 'go up to 350-400 dollars, but what are the chances ...

Address book budget phone - it's quite modest by opportunities database. Name, phone number, yes. In fields more expensive models, but the screen is still tiny. To view all need to use scrolling. On a large screen of your Pocket PC contact information to view a much more comfortable. For example, a good targeted bases of graphs have to remember anniversaries - birthdays, or any other events. It is easy to find a man who is not a sin to congratulate the upcoming holiday. Choose a name, click on the screen pen. And the phone begins to dial in to the subscriber. Kindly talk to ... And what is there to give an e-mail, eternal and still a pipe dream of every owner of a Pocket PC? There are no problems. If the phone has a modem, just run on the PDA email program and select the "get mail". The operation did not take long and does not require large cash expenditures, even if your phone does not support the exchange of protocol packet data GPRS (though not while receiving almost exclusively on a cellular channel, and only using wireless access to e-mail server as needed) . If your disposal does not modest Palm, a luxury Pocket PC, then via Bluetooth and you can wander over the WAN, and their own ringtones for your phone write out of one's own head. Equipment by means of multimedia Pocket PC is that allows you to run a real audio editor, to write in it's own melody and surpass it in the phone memory. (A hypothetical proposal, because my own experience in this area, I have not, but sincerely believe that for a computer running Windows CE nothing is impossible). Finally, sync your phone and desktop computer ... Always looked at this possibility with a secret envy. I have somewhere to say that in my laptop no serial port. A cheap "Eric" is able to synchronize with your computer - with a special cable - only through the port COM. (Blee-and-in ", said to my nine-year-daughter, risking to go in the corner - oh, this Masyanya, all that know her). Bluetooth eliminates this problem, although the pleasure adds quite a bit. Yet to take full advantage of the wireless interface should have a decent modern phone with a modem ... Phones with built-in organizer, and quite bulky phone book synchronization with the PC and update the data of both.That is scheduled to MS Outlook (and other compatible programs such as Lotus Organizer, one of the best on this day, organizers), the events will be rewritten in the calendar, cell phone address data from the Contacts folder - in the phone book. Plus the same ringtones, downloaded from the Internet or written by yourself.

Well, smart phones with advanced multimedia features - with built-in MP3 player, especially with digital cameras - a Bluetooth receive an extra degree of freedom. How not add to the smartphone memory (yes, not all smartphones allows it), no matter how squeezed files MP3, and space for multimedia data is still lacking. Wireless connectivity allows you to quickly change a set of tracks in the phone memory or to overwrite the captured footage on a laptop hard drive. Not for nothing that the newest models of smartphones are equipped with a Bluetooth adapter nominally ... Say what you like, and all the pleasures of the use of Bluetooth has to be evaluated only on the eye. Most of us have Bluetooth adapters yet ... But whether this upset? Remember the rule of transition to a new operating system? Do not rush. Do not hurry to get rid of the old errors, replacing them with new ones. Let the developers will release the first service pack, then ventured ... Roughly the same with Bluetooth. We have heard the very first, still damp with the heat from the heat, the device. Tomorrow will come the products of mass, waste, devoid of most of the flaws still largely ad implementations ... However, this concerns mainly the computer modules. How strange, but the phone Bluetooth adapters are available with respect to long for many users stopped being difficult to access exotic. We in Russia? No, they have in the west ... But what, in principle, the difference? The authors, translation:
