GSM / GAN - Market Requirements

Historically, AudioCodes has provided and continues to supply GSM over IP Media Gateway solutions to enable the use of IP-BSC/BTSs within legacy GSM radio networks. With the commercial introduction of UMA (Unlicensed Mobile Access), also known as Generic Access Network (GAN), GSM mobile operators are able to provide service to users over WiFi as well as GSM radio networks with the use of WiFi/Cellular handsets. As UMA continues to gain popularity among GSM operators as a means to provide service to users over WiFi, AudioCodes is well positioned with a comprehensive set of media gateways and security gateways into any UMA compliant network.
