Abstract
An antenna test system is used for testing wireless telecommunication systems. In an embodiment of the invention, the test system includes an antenna array comprising a plurality of individual antennas that are deployed in a pattern within a confined testing area such as in a building or laboratory. A plurality of base stations are selectively connected to the antennas via an antenna matrix. When the antenna matrix makes a connection between a base station and an antenna, a cell is activated accordingly. At least one mobile is positioned in fixed location and operates within range of an activated cell wherein various test procedures are run and monitored by a remote computer workstation. The invention is particularly suitable for testing problems associated with handoff procedures and interference by sequentially shifting activated cells relative to the stationary mobiles. The inventive technique provides consistent conditions necessary for repeat testing for use in system optimization.
