No one is going to say it?Edgewater doesn't use beamforming technology. In fact they have positioned themselves in competition with it. From their own paper, September, 2015
Microsoft Word - 80211ac Challenges in High Density Networks.docx (edgewaterwireless.com) Challenges in Beamforming in High Density Networks In the IEEE 802.11n specifications, there exists no standardized sounding and feedback protocols to support beamforming. A beamforming access point makes direction decisions without explicit feedback from STAs with which it is communicating. Further, government regulations limit the transmit power of beam formed transmitters according to the antenna gain such that EIRP is only moderately greater than that of an omnidirectional antenna. NOTE: beamforming antenna array elements are largely omnidirectional so beamforming can only occur in the azimuth (horizontal) plane. The benefit of beamforming is that it minimizes the probability of co-channel interference (CCI) between access points in low client density environments. NOTE: Beamforming will not be effective in a high density client environments as avoidance of CCI will become unattainable.
