Wavion: Benefits of Beamforming and SDMA in WiFi Access Point for Metropolitan-Area Deployment
The paper presents the performance gains of a multi-antenna AP for metropolitan-area WiFi deployments, which is gaining traction around the world. The AP has a 6-antenna array and implements single-user maximum ratio combining (MRC) and transmit Beamforming (BF), as well as multi-user four-fold spatial division multiple-access (SDMA). The clients use standard WiFi 802.11a/b/g NICs. We present significant performance gain over a conventional WiFi AP, which amounts to doubling the range and quadrupling capacity.
