Abstract:
1. An apparatus comprising: at least one processor configured to obtain measurements of a signal strength of each frequency band transmitted by a first communication system with which a wireless device is not in communication, wherein each frequency band comprises a broadcast television band, wherein the at least one processor is configured to determine location information and a timestamp for each of the measurements and to associate the location information and the timestamp with a particular measurement of signal strength, wherein the first communication system comprises a broadcast television system, to store the measurements until a voice call or a data connection is established for a reason other than to send the measurements, to send the measurements of the signal strength in the broadcast television system and associated location information and timestamps via a second communication system, and to obtain information regarding whether the apparatus is within a coverage area of a particular frequency band, wherein the measurements of the signal strength are for at least one frequency band that is not used by the second communication system, and wherein the second communication system is a cellular system; and a memory coupled to the at least one processor.
