1. A method comprising:

  • periodically interrupting a frequency hopping process while a call is in progress, wherein said periodically interrupting comprises routing said call to an RF beacon transceiver apparatus, and wherein said frequency hopping process is of a frequency hopping adaptive base transceiver station having an adaptive antenna array including RF traffic transceiver apparatus chains;

    calibrating an antenna transmit path for one of said RF traffic transceiver apparatus chains at a frequency selected from a plurality of predetermined frequencies defined by a hop list to determine a set of weighting parameters for said antenna transmit path at said frequency; and

    returning said call to said frequency hopping process,wherein said calibrating comprises calculating adjustment values to achieve a best or a desirable null for said one of said RF traffic transceiver apparatus chains.
