ABSTRACT:
A small office/home office base transceiver station (SOHO BTS) server capable of managing interference by correlating pilot strength measurements sent by mobile devices and directing the attenuation settings for each transmit path. An array of antennas coupled to an array of transmit paths are selectively activated one at a time. When a transmit path is activated, the SOHO BTS server sets the associated variable attenuator to its maximum level. The SOHO BTS server detects whether a radio environment report or and a pilot strength measurement message (PSMM) containing information about a mobile station's pilot strength is present. When the pilot strength is greater than a predetermined value, the SOHO BTS server increases the setting on the attenuator. Otherwise, the SOHO BTS server decreases the attenuator setting until such pilot strength information is available or if the lowest attenuator setting has been set. The other transmit paths are also tested accordingly.
