UMA is an acronym for Unlicensed Mobile Access which is an access technology that allows subscribers to switch between fixed and mobile networks, without dropping a phone call.

UMA enables subscribers to switch between a Wide Area Cellular Network (WAN) to a Wireless Local Area Network (WLAN). This delivers high-performance, low-cost mobile voice, data and IMS services to subscribers over the broadband Wi-Fi access networks, dramatically increasing mobile service usage and decreases the costs for operators. It uses Bluetooth or 802.11 for wireless connections in your home or office.

UMA is part of the 3GPP (3rd Generation Partnership Program.)
