Wi-Fi to 3G handover tested
Nortel and Japan's BB Mobile have achieved what is believed to be the world's first seamless handoff of voice and data services between a 3G cellular network operating on the 1.7 GHz radio frequency band and a wireless local area network (802.11 LAN). This seamless mobility is enabled by intelligence built into the network by Nortel.
Setting a new benchmark in convergence, this real-world field test builds on another wireless data transmission success by Nortel and BB Mobile earlier this month. The previous trial achieved Japan's first 14.4 million bits per second (Mbps) wireless data transmission using the 1.7 GHz radio frequency band for mobile communications and Nortel's high-speed downlink packet access (HSDPA) technology to deliver speeds 30 times faster than commercially deployed networks using UMTS.
Both BB Mobile trials were held in Japan's Tokyo and Saitama prefecture using a live UMTS network at 1.7GHz with Nortel's core network and access network including base stations. The HSDPA tests were conducted after a trial license for W-CDMA at 1.7GHz spectrum was issued by Japan's telecommunications regulator on May 30, 2005
