摘要： In one embodiment, a method for adjusting a radio-frequency coverage map. The method includes receiving calibration data comprising observed received signal strength values at one or more calibration points corresponding to a radio frequency transmitter, and identifying an applicable coverage map, where the coverage map provides, for the radio frequency transmitter, estimated received signal strength values at one or more locations. The method also includes determining one or more offset values at the one or more calibration points, where an offset value is based on a difference between an observed received signal strength value and an estimated received signal strength value at a given calibration point. The method also includes adjusting one or more estimated received signal strength values at one or more location bins of the coverage map based on a distance from the one or more calibration points and the one or more offset values.
