WILLCOM Achieves 20Mbps Transmission Speed at Wireless Station Trials of Next Generation PHS System
- Towards the Realization of Wireless Broadband -
|
WILLCOM, Inc. acquired a license for a wireless station to conduct trials on its next generation PHS system from the Ministry of Internal Affairs and Communications on August 1, as part of its corporate activities to develop and introduce the system.
The Company has been conducting trials with regard to the development and introduction of its next generation PHS system by focusing on testing the transmission of the OFDM system in the 2.5GHz range, and it is pleased to announce that in trials conducted at the wireless station, it achieved its first stage target speed of 20Mbps.
Going forward, WILLCOM will continue to improve existing trial facilities and conduct tests and evaluation activities with regard to the development and introduction of its next generation PHS system.
WILLCOM strives to make data communications more convenient for its approximately 2 million customers, while turning wireless broadband into a reality and making the next generation system a practical one. Accordingly, the Company has been intensifying efforts to popularize wireless broadband not only in Japan but also overseas through standardization and promotional activities at related international institutions and organizations such as ITU (International Telecommunication Union) and PHS Mou Group.

The trial is scheduled to commence in early August 2006 and last for one year after the acquisition of the license.
|
Antenna and base station trial facilities will be set up in two locations: a building in the Toranomon area of Tokyo and a suburban area.
|
The trial will be carried out to mainly evaluate the performance of OFDM technology, a core technology of WILLCOM's next generation PHS system, in the 2.5 GHz spectrum, when adaptive array antenna technology is applied to it. The Company will also test the system's performance when MIMO technology is applied.
