Abstract: In a cellular communications system having a plurality of cells, each cell being served by at least one of a plurality of existing base stations, a method of determining a location for a new micro base station antenna involves first providing a test antenna at a test location in one of the cells. Then, for a predetermined time period, a monitoring procedure is performed to assess how many mobile stations are close enough to the test location that they would be served by a micro cell having a base transceiver antenna at the test location. The monitoring procedure involves, in the test antenna, receiving an uplink access attempt signal that is transmitted from a mobile station to an intended one of the existing base stations. Then, signal strength of the received uplink access attempt signal is measured and compared to a predetermined threshold level. If the measured signal strength is greater than the predetermined threshold level, then a count value is incremented.
