Abstract:
A method for collecting and processing received signal level data over a wireless system, comprising the steps of:gathering an incomplete set of data of signal strength levels from closely spaced locations at which a mobile unit is likely to communicate with one or more base stations without disruption or modification of the normal operation of the wireless system; associating the elements of said gathered data with geographic locations corresponding to the location at which each data element was gathered; determining the signal strength of each element of said gathered data; identifying a digital identification code within said gathered data; normalizing said data to a set of bins defined by a grid applied to said wireless system; determining a variance relationship of said gathered data based upon the correspondence of signal strength variation to spacial separation of said data elements; recognizing the location of data elements missing from said complete set of locations within said wireless system; interpolating the probable signal strength values of said missing data elements from said gathered data, said corresponding geographical locations and said variance relationship.
