Patent ID: 7519353

Claim:
A telecommunications system indicating an optimal range of frequencies of electromagnetic waves among a plurality of nonoverlapping ranges of frequencies of electromagnetic waves, the system comprising: a mobile voice communications device configured to: receive the plurality of nonoverlapping ranges of frequencies of electromagnetic waves; and transmit a communications signal indicating an average power received for each range of the plurality; and a controlled interface point in communication with the mobile voice communications device, configured to: receive the communications signal indicating an average power received for each range of the plurality; receive information from a database which associates a cost with each range in each of a plurality of geographic regions, wherein the cost associated with one or more of the ranges is different in a first geographic region than in a second geographic region among the plurality of geographic regions; receive information indicating that the device is located in the first geographic region and is located outside the second geographic region; determine the optimal range of frequencies based on the cost associated with each range of the plurality in the first geographic region and the average power received from each range of the plurality; and transmit a communications signal indicating the optimal range of frequencies; wherein each range of the plurality is associated with a different provider of communications services.
