ABSTRACT:
Various embodiments for providing multi-band operation in a mobile computing device are described. In one or more embodiments, a mobile computing device may be arranged to support quad-band GSM communication in the GSM-850, GSM-900, GSM-1800, and GSM-1900 frequency bands. The mobile computing device may be arranged to determine a starting frequency band based on the home country and home network. By using the determined starting frequency band associated with the home country and home network of the user, fewer and/or shorter delays may be experienced when searching for and acquiring an available frequency. Once a network search is completed, the mobile computing device may be arranged to determine whether a network can be found in current frequency band pair for normal service, to disconnect from the acquired network if normal service is not supported, and to intelligently search for an available frequency in a different frequency band. Other embodiments are described and claimed.
