Abstract

Systems, method and apparatus are described for reducing unauthorized usage in a television distribution system. A television receiver communicates with base stations of a wireless communication network. Based on the communications with the base station, the television receiver identifies its location and transmits the location information to a data collection system through the wireless communication network. The data collection system utilizes the location information to identify unauthorized uses of the television receiver.
