Generating wireless coverage maps

A wireless coverage mapping system comprising:

• at least one processor coupled to at least one memory containing instructions which, when executed by the at least one processor, causes the system to perform processes comprising:
• receiving, for each of a plurality of mobile devices communicating wirelessly with a server system, mobile device location information and mobile device communication service information;
• generating a dead zone volume map based on the mobile device location information and the mobile device communication service information, the dead zone volume map defining a dead zone volume for a wireless communication service;
• generating a dead zone geofence boundary volume map based on the dead zone volume map, the dead zone geofence boundary volume map defining a geofence boundary relative to the dead zone volume and further defining a buffer zone between at least a portion of the geofence boundary and at least a portion of the dead zone volume, the buffer zone defining a zone in which the wireless communication service is available for at least one of the mobile devices, wherein the geofence boundary of the dead zone geofence boundary volume map is based on an amount of data to be transmitted to a mobile device to provide sufficient time to transmit the amount of data to the mobile device while the mobile device is in the buffer zone between the geofence boundary and the dead zone volume;
• and
• upon determining that a given wireless device has reached or crossed the geofence boundary, beginning transmission of the amount of data to the given wireless device.

A computer program product comprising at least one tangible, non-transitory computer-readable storage medium having embodied therein computer program instructions which, when executed by one or more processors of a system, cause the system to perform computer processes comprising:

• receiving, for each of a plurality of mobile devices communicating wirelessly with a server system, mobile device location information and mobile device communication service information;
• generating a dead zone volume map based on the mobile device location information and the mobile device communication service information, the dead zone volume map defining a dead zone volume for a wireless communication service;
• generating a dead zone geofence boundary volume map based on the dead zone volume map, the dead zone geofence boundary volume map defining a geofence boundary relative to the dead zone volume and further defining a buffer zone between at least a portion of the geofence boundary and at least a portion of the dead zone volume, the buffer zone defining a zone in which the wireless communication service is available for at least one of the mobile devices, wherein the geofence boundary of the dead zone geofence boundary volume map is based on an amount of data to be transmitted to a mobile device to provide sufficient time to transmit the amount of data to the mobile device while the mobile device is in the buffer zone between the geofence boundary and the dead zone volume;
• and
• upon determining that a given wireless device has reached or crossed the geofence boundary, beginning transmission of the amount of data to the given wireless device.
