Systems and methods for measuring the performance of a provider of communications service are described. A plurality of mobile communications devices measure average power received, signal to noise ratio, voice quality, blocked and dropped calls, or any combinations of such measurements. The device may also receive a set of data identifying the location of the device. The device may transmit one or more communications signals to a server computer system with such measurements and location data. The measurements and location data may be stored in a database, and new data may be created and transmitted illustrating a subset of the measurements and location data.
