15 Gb / s “over the air” - this is real

    While the Wi-Fi Alliance is moving towards finalizing the specifications of the IEEE 802.11n protocol and trying to squeeze the maximum 248 Mbit / s out of it, a group of American researchers from Georgia Electronic Design Center (GEDC) managed to achieve much more impressive results, although under less favorable conditions for the end user .
    15 Gbit / s.  True, only a meter.
    We are talking about the standard 802.15.3, in which engineers were able to demonstrate an impressive data transfer rate "over the air" - about 15 gigabits per second. True, such a high speed can be maintained only under one important condition: the receiver and transmitter must be in direct line of sight from each other at a distance of no more than a meter. If you increase the gap to two meters, the speed will drop to 10 Gb / s. If you spread the antennas five meters apart, the bar will drop to around 5 Gb / s, which, however, is still enough to merge the contents of one DVD in a few seconds.

    The new standard, called 802.15.3C, is planned to be used in the so-called Personal Access Networks. For example, in content kiosks, which are widely used in many countries and imply data transmission over a distance of about a meter.

    Engineers developing the standard have not yet announced the exact dates for the commercial implementation of the technology and say that the technology needs some refinement in terms of energy consumption and increased throughput.
