Abstract:
A process for optimizing the performance of a wireless communication system, comprising the steps of:for each of a number of sector signals: measuring a received signal strength of said sector signal at a plurality of measurement points within the bounds of a test region; for each of said plurality of measurement points, averaging the values of said received signal strength, for said sector signal, measured at a number of the closest measurement points, to the measurement point under consideration, with the value of said received signal strength, for said sector signal, measured at the measurement point under consideration; for each of said plurality of measurement points within the bounds of a test region: determining a likely server sector based upon the relative values of said number of averaged received signal strengths for said measurement point; determining a number of likely interferer sectors based upon the relative values of said number of averaged received signal strengths for said measurement point; and for each individual one of said number of likely interferer sectors, calculating a product obtained by multiplying an estimate of said individual sector's likelihood of transmission by a weighting value indicating the relative value of said individual sector's average signal strength to said likely server sector's average signal strength; determining a weighted probability that at least one of said number of likely interferer sectors will be active at some time, by mathematically combining said calculated products; and ascribing said weighted probability as a magnitude of measurement point interference.
