Nokia said it has begun performance testing of its fixed-mobile convergence technologies by using the 6136 handset and UMA (Unlicensed Mobile Access) over WLAN. During the next two months, 50 families in Finland will use the technology. Nokia chose UMA because users are able to roam between LANs and WANs using a single device. Transfer from one network to another (either GSM, GPRS or UMTS), should, theoretically, be seamless. The handsets are able to make calls over the Internet using WiFi, Nokia said. Article
