Unlicensed Mobile Access

Unlicensed Mobile Access

Unlicensed Mobile Access (UMA) is a technology that allows seamless handover of voice and data services between cellular networks and unlicensed wireless networks, such as Wi-Fi. This enables users to make calls and use data services over a Wi-Fi connection when they are within range of a Wi-Fi hotspot, without needing to rely solely on cellular coverage.

How does Unlicensed Mobile Access work?

UMA works by extending the capabilities of existing cellular networks to include unlicensed wireless networks. When a user with a UMA-enabled device enters the coverage area of a Wi-Fi hotspot, the device automatically switches from the cellular network to the Wi-Fi network, allowing the user to make calls and use data services over Wi-Fi.

Benefits of Unlicensed Mobile Access

One of the key benefits of UMA is improved indoor coverage and call quality. By offloading traffic to Wi-Fi networks, cellular networks experience less congestion, resulting in better call quality and faster data speeds for users. Additionally, UMA can help reduce roaming charges for users traveling abroad, as they can use Wi-Fi networks for calls and data instead of relying on expensive international roaming agreements.
