Abstract: 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 assigns instructions to the subscriber units based at least in part on the subscriber unit's past use of bandwidth.

Abstract: A patch array antenna includes a planar base on which is defined a ground plane and feed positions that are electrically isolated from the ground plane. A plurality of patch elements are configured to resonate over a predetermined frequency range. Each patch element is isolated from the ground plane and disposed on the base over the ground plane so that an air dielectric is defined between the patch element and the ground plane. Each patch element defines a resonant portion that is electrically connected to a respective feed position. A feed network is defined on the base that electrically connects the feed positions to one or more output points on the base.

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.
