Abstract
A base station for use in a mobile telephony network includes an antenna arrangement coupled to a transceiver arrangement for producing a plurality of beams. A method of testing the base station comprises detecting at the transceiver arrangement the signal strengths of a test signal received via the beams; comparing and/or correlating the said signal strengths detected at the transceiver arrangement; and using the results of the comparisons and/or correlations to determine the configuration of the antenna arrangement and transceiver arrangement and/or to detect faults. The comparison of average signal strengths can be used to detect cabling faults, and beam errors. The correlation of un-averaged signal strengths can be used to determine which beams have the same polarization. Beam pointing directions and the allocation of antennas to sectors can be determined by monitoring handovers of mobiles moving between cells. Frequencies may be allocated to sectors according to a frequency re-use scheme.
