Nokia Corp has completed voice and data calls using unlicensed mobile access, or UMA, technology at one of its US centers.
The Finland-based company hailed the calls as a convergence milestone. Essentially, UMA enables mobile operators to use wireless local area networks as an extension of their cellular networks.
UMA lets operators seamlessly transfer voice and data services from cellular to WiFi access networks. It is one possibility for operators to automatically switch a voice call from a cellular to a mobile VoIP system, for example. Nokia said UMA would increase mobile service usage and decrease costs of network deployments.
We’re one step closer to simplifying the end-user mobile experience to access voice, personal information, and multimedia services on one device irrespective of their location, said Mark Louison, SVP of Networks at Nokia, North America, in a statement.
The voice calls were conducted from a live cellular network to WLAN and from WLAN to cellular. A data call was placed from cellular to WLAN. Both types of calls were made using a Nokia test phone.
