UMAN – Unlicensed Mobile Access Network
An Unlicensed Mobile Access Network is derived by utilizing existing unlicensed radio technologies such as WiFi (Wireless Fidelity) and Bluetooth ¨ to extend GSM and GPRS services into customer sites. This is achieved by introducing a UNC (Unlicensed Network Controller) into the network which connects the existing GSM and GPRS core network, through a broadband IP network, to the Access Point situated in the customer site. As such, customers can switch between the traditional GSM / GPRS network and the UMAN as the move into and out of coverage. Although the title UMA is often still used, the technology is now termed GAN.
