Unlicensed Mobile Access (UMA) and generic access network (GAN) are terms describing the system that allows a BlackBerry smartphone enabled with Wi-Fi® technology to access the mobile network through a wireless local area network (WLAN). The terms UMA and GAN are interchangeable.
Within the UMA/GAN system, a smartphone enabled with Wi-Fi technology connects to a WLAN and establishes a secure Internet Protocol (IP) connection to a generic access network controller (GANC).
UMA/GAN may require the configuration of ports 4500 and 500 on the home network. Contact your wireless service provider for information on the configuration of ports on home networks.
Contact your wireless service provider for information regarding the availability and use of UMA/GAN.
