Abstract:
An information processing system for testing RF coverage reliability of a signal transmitted by a base station in a radiotelephone system cell comprising:processing circuitry for receiving information characterizing said cell and outputting in response test information, said processing circuitry operable to:estimate a radius R of said cell in accordance with the formula:Cell Radius R.apprxeq.10.sup.-(P.sbsp.THRESH.sup.FM.sbsp..sigma..sup.-A')/Bwhere: P.sub.THRESH is the desired signal strength threshold, FM.sub..sigma. is the fade margin and A' and B are propagation parameters;estimate a bin size for each of a plurality of bins partitioning said cell;estimate a minimum drive distance for validating RF coverage of said cell from said estimated radius and said estimated bin size; andselect a number of road segments having a combined length exceeding said estimated minimum distance.
