[BB Mobile and Nortel complete Japan's first HSDPA transmission.]

Tokyo -- 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 Universal Mobile Telecommunications System (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 will showcase some of the test results during Networld+Interop 2005 Tokyo beginning June 6, 2005.

HSDPA is designed to advance wireless capabilities through delivery of new services like real-time DVD quality video, gaming applications, videoconferencing and split-second multimedia collaboration for business.
