A point to multipoint wireless communication system includes an access
point having an antenna, a processor, and circuitry in communication with
the access point antenna and controlled by the access point processor to
transmit wireless electromagnetic signals to, and receive wireless
electromagnetic signals from, an area. A plurality of subscriber units
disposed within the area each has an antenna, a processor and circuitry
controlled by the subscriber unit processor to transmit wireless
electromagnetic signals to, and receive wireless electromagnetic signals
from, the access point. The access point allocates data bandwidth among
the subscriber units based at least in part on the subscriber units' past
use of data bandwidth.
