.@802.11ax: Not just another higher data rate by John Lukez

As a result, power control is needed to ensure that a user very close to the access point (AP) does not drown out another user farther from the AP. Widely different power levels between users at the AP will result in increased inter-carrier interference (ICI), receiver compression, leakage, and carrier frequency offset (CFO) due to timing misalignments between Wi-Fi user/station (STA) devices. In 802.11ax, the AP commands the STAs to adjust their power up or down based on the target received signal strength indicator (RSSI ) at the AP side. The STA first estimates path loss by subtracting measured RSSI (at STA) from AP transmit power (encoded inside the packet). The STA then transmits a signal with power equal to the target RSSI plus estimated path loss. Devices closer to the AP transmit less power while devices farther away transmit more power to overcome the greater path...
