Japan's BB Mobile, a Softbank Group company, and Nortel have completed what is believed to be Japan's first 'supercharged' wireless data transmission of 14.4 million bits per second (Mbps) -- 30 times faster than today's commercially deployed wireless networks -- using UMTS technology. Live field tests were conducted with mobile handsets on BB Mobile's wireless network built by Nortel.
The trial, using the 1.7 GHz radio frequency band for mobile communications, was the first time high-speed downlink packet access (HSDPA) technology has been demonstrated by any operator or wireless infrastructure supplier in Japan based on published announcements. BB Mobile and Nortel conducted HSDPA testing after a trial license for W-CDMA at 1.7GHz spectrum was issued on May 30, 2005.
Nortel recently completed the industry's first HSDPA trial in Israel with Partner Communications. Nortel has also announced a series of industry milestones with leading chipset and data card vendors. Nortel has worked with a number of wireless operators on HSDPA trials and deployments in 2005, including mmO2, Orange (at 3GSM World Congress 2005 in Cannes, France), Vodafone (at CeBIT 2005 in Hanover, Germany) and mobilkom austria.
The BB Mobile trial was held in Saitama prefecture using Nortel's core network for mobile communications and access network, including base stations. BB Mobile and Nortel plan to continue to work together on new wireless technologies in order to provide the best wireless experience for BB Mobile's customers."
