15 Gbit / s "through the air" is real
While the Wi-Fi Alliance is moving toward finalizing the IEEE 802.11n protocol specifications and trying to squeeze the maximum 248 Mbit / s out of it, a group of American researchers from the Georgia Electronic Design Center (GEDC) managed to achieve much more impressive results, though with less favorable conditions for the end user .
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 high speed can be maintained only under one important condition: the receiver and transmitter must be in direct view of 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 Gbit / s. But if you spread the antennas five meters apart, the bar will drop to the 5 Gb / s mark, 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 (Personal Access Networks). For example, in the kiosks, which are widely used in many countries and involve the transfer of data over a distance of about a meter.
The engineers who are developing the standard have not yet named the exact dates for the commercial introduction of the technology and say that the technology requires some refinement in terms of power consumption and increase in throughput.
