A method for mobile communication by access points in a wireless local area network
(WLAN) includes transmitting a first downlink signal on a common frequency channel
from a first access point to a first mobile station, at a first downlink power
level, which is adjusted responsively to a first uplink power level transmitted
from the first mobile station to the first access point. If the first downlink
signal received at a second access point is below a predetermined interference
threshold, the second access point may transmit a second downlink signal on the
common frequency channel to a second mobile station, simultaneously with transmission
of the first downlink signal from the first access point to the first mobile station.
The capacity of the WLAN may thus be substantially increased.
