  • Apparatus and method for mobile station-assisted optimization of a wireless network
    Patent number: 8190145
    Abstract: A radio frequency (RF) coverage server for use in a wireless network comprising base stations that communicate with mobile stations located in a coverage area of the wireless network. The RF coverage server receives from the mobile stations geographic location data indicating positions of the mobile stations when communication links to the wireless network were dropped. The RF coverage server identifies areas of good RF coverage and areas of poor RF coverage in the wireless network. The RF coverage server also identifies a first one of the mobile stations that frequently drops communication links to the wireless network when the first mobile station is disposed in the good RF coverage areas.
