Abstract
Systems and methods for remotely evaluating antenna installations in a mobile radio communication system, wherein each antenna installation comprises at least one pair of antenna elements arranged for diversity reception. The received signal strength from a plurality of mobile stations is measured at the respective antenna elements of each pair of antenna elements; the signal strength values from each antenna element are compared for each pair of antenna elements; and, a plurality of comparison results are visually presented on a display as a function of both the comparison result and a parameter related to the position of each of the plurality of mobile stations relative to the location of the base station, whereby differences in reception characteristics between antenna elements of each pair can be detected and such pair can be identified for maintenance.
