Mobile Marketing: The History of Mobile Network Technologies - UMA

Similar to FemtoCell, UMA is deployed through a base station that uses WiFi signals to carry voice and data from mobile handsets to a base station. The base station provides improved access to GSM and GPRS by tapping into unlicensed aspects of the network spectrum. In the United States, this is being promoted by T-Mobile; in the United Kingdom, it is being promoted by British Telecom.
