UMA - Unlicensed Mobile Access


Unlicensed Mobile Access (UMA) is a technology that was originally intended to provide seamless access to GSM, GPRS and UMTS mobile networks over unlicensed spectrum technologies, such as Bluetooth and Wi-Fi (IEEE 802.11). Nowadays, UMA is renamed Generic Access Network. This term is used because the technology can be used to deliver mobile services over any broadband acces technology, not only Wireless LAN. GAN defines a secure, managed connection from the mobile core network to different devices or access points over IP.

The user can access its mobile services and be reached on its mobile telephone through other wireless local area networks at home, the office or at hot spots. The user will be able to roam freely and seamlessly between cellular networks and unlicensed wireless networks. The user will need a dual-mode enabled mobile terminal.

GAN defines a parallel connection to the mobile network. A special GAN network controller (GANC) makes he connection between the IP network and the core mobile network.
