WLAN, 3G Handoff Tests Successful
The mobile phone industry Tuesday heard loud and clear from Nortel and BB Mobile, a Softbank Group company, when the pair announced test calls demonstrating uninterrupted high-speed voice and data sessions. The test calls, completed on a live (UMTS) 3G network and an 802.11 wireless LAN, exhibited a seamless hand-off of voice and data services between a 3G network operating in the 1.7-GHz frequency band and a WLAN, the companies said, claiming the development dials up a new benchmark in convergence.
