Bluetooth 3.0: Hybrid approach

Speed, speed, and speed again. 22-26 Mbit / s - that is, according to director Michael Foley, Bluetooth SIG, will be the real rate of exchange for Bluetooth 3.0 + HS (recently logically stands for High Speed). In the world, and so hundreds of millions of Bluetooth-devaysov, but mostly it's the device that do not require high-speed connectivity - mouse, headset, ... Now Bluetooth SIG (Special Interest Group), engaged in the promotion of a standard organization, wants to achieve for the third version of BT widespread as a means of connecting the most demanding devices - such as video cameras or media players for audio and video transfer.

What accounts for a tenfold leap in performance? It's very simple: the new Bluetooth - this is not Bluetooth, and a mixture. The role acts as a good old radioprotokola 802.11 familiar to us from WiFi, Bluetooth 2.1 and is used only for "the first dating and mating."By the way, in a recent interview, Foley suggested the possibility of software upgrades laptops, having on board both modules to the level of BT 3.0 + HS. Something in the 2.4 GHz band is becoming quite crowded, because soon a new Bluetooth will add to the different cameras and players.

Another bonus update - Optimization of energy consumption. The new chipsets own power schemes will be optimized so well that, according to the developers, manufacturers, Bluetooth in handsets and iPods can not turn off - and the battery life of this will not change significantly. However, the phones, according to his own experiments in transport, and so many do not turn off ... As for the specific circuits power distribution, the 802.11-part will be turned off all the time, except for direct data transfer process.

After final approval of specifications, the new version of Bluetooth in the Tokyo session, many firms have announced new chips BT3.0 + HS. The first shot out the guys from Broadcom, whose chip InConcert BCM4325, combining WiFi a / g / n, Bluetooth and FM-radio, has been certified to be 3.0 + HS. Together with the appropriate certified software. Even more interesting solution offers the Cambridge Silicon Radio, whose chip CSR9000 than brodkomovskim can boast yet integrated GPS. Closes the top three Atheros chipset, with its modest AR3011 - modest because it is simply WiFi + BT, and no extraneous bells and whistles. However, for the operation of Bluetooth 3.0 and nothing more is needed.

What we have in the bottom line? First, it would be good as soon as possible to wait for the corresponding devices from Intel. I do not think that with such massive support Intel uvernetsya of his duties, and given the close connection and WiFi BT3.0 should probably just live up to some Intel 5550, where more and WiMAX will be. Concerned in connection with the new standard, perhaps, only one - as if to knock on the head champions of the copyright does not insist on imposing restrictions on the transfer of files. Taking into account the capacity of the new standard and its original orientation on the transfer of large multimedia files such danger, unfortunately, exist.
