UMA - Unlicensed Mobile Access

Unlicensed Mobile Access is an industry collaboration to extend GSM and GPRS services into customer sites by utilizing unlicensed radio technologies such as Wi-Fi (Wireless Fidelity) and Bluetooth^®. This is achieved by tunnelling GSM and GPRS protocols through a broadband IP network towards the Access Point situated in the customer site and across the unlicensed radio link to the mobile device.
