Особливості технології МІМО у стандарті 802.11

Abstract

In this paper, the research in MIMO technology standard 802.11, which was fairly widespread in wireless networks. This was offered her analysis as a wireless channel in which there is a plurality of sub-channels, occupying the same frequency resource and described two groups of extensions channel and physical levels. During the studies found that while the use of multiple antennas radiation ought to increase the zone of confident reception and the existence of parallel spatial channels can increase throughput flow. But in this case it gives rise emergence of a number of destabilizing factors that require further research in the real world.
