Systems and methods for telecommunications network coverage optimization are disclosed. The network coverage optimization system computes a usability index value for a geographic area using measured values of telecommunications network usability indicators. The telecommunications network usability indicators are related to network coverage (e.g., whether the user has enough bars and can make a call), quality of service (e.g., whether the speech and data quality are good), and data speed (e.g., the amount of buffering the user is experiencing). The telecommunications network usability indicators can be selected based on an importance rating associated with them. Then, for each geographic area, the network coverage optimization system computes a score value and a weight value for each selected telecommunications network usability indicator. Using the computed score values and the computed weight values, the network coverage optimization system computes a usability index value for the geographic area.
