A method and system for wireless admission control. The system monitors the air interface load in various wireless coverage areas, such as sectors for instance. When the load exceeds a designated level, the system begins making call admission decisions based on whether the calls involve mobile wireless devices (such as handheld cell phones) or fixed wireless devices (such as wall-mounted cell phones or wireless local loop hubs). Further, the system may additionally base its admission decisions on the type of bearer traffic carried by the calls, such as whether the calls carry voice, fax or data traffic.
