NXP Semiconductors’ Unlicensed Mobile Access (UMA) cell-phone solution is being deployed in the first nationwide, commercial rollout of a UMA-based service in North America — the T-Mobile HotSpot @Home service. NXP’s chips are used in Samsung Electronics T409 dual-mode handset, which is one of the two devices initially supported by the T-Mobile service. NXP’s UMA-enabled Nexperia cellular system solution enables the Samsung phone to seamlessly switch between conventional cellular networks and Wi-Fi hotspots at home, in the office and other public areas for voice, data and multimedia calls.
