Fujitsu's Compact Mobile WiMAX Base Station Selected by UQ Communications

-Mobile WiMAX infrastructure development in Japan will serve as springboard to global markets-

Fujitsu Limited

Tokyo, March 03, 2008

Fujitsu Limited today announced that its outdoor base station for mobile WiMAX, BroadOne WX300, has been selected by UQ Communications Inc. for the development of the company's nationwide WiMAX services infrastructure in Japan.

 BroadOne WX300 Macro Base Station

UQ Communications is a mobile WiMAX operator in Japan that is jointly owned by KDDI Corporation, Intel Corporation, East Japan Railway Company, Kyocera Corporation, Daiwa Securities Group Inc., and the Bank of Tokyo-Mitsubishi UFJ, Ltd.

Fujitsu is positioning its mobile WiMAX base station equipment as a premier solution for the rapidly emerging wireless broadband market as the company aggressively expands its business in this market both inside and outside of Japan.

The mobile WiMAX operator UQ Communications intends to begin offering commercial WiMAX service in Japan starting in 2009. As a critical part of its infrastructure, the company has selected the Fujitsu BroadOne WX300, the world's smallest outdoor WiMAX base station, for its outdoor base stations. The BroadOne WX300, which was developed by Fujitsu to be light, energy-efficient, and the smallest base station in its class(1), will accelerate the spread of wireless broadband access throughout Japan.

Features of the BroadOne WX300 Macrocell Outdoor Base Station

The single-unit outdoor base station chosen by UQ Communications features world-class efficiency and performance. The unit's high-output transmitter (amp) uses a gallium-nitride (GaN) High Electron Mobility Transistor (HEMT) device(2) that was developed based on ultra-high-speed transistor technology invented by Fujitsu. This device is coupled with Fujitsu digital pre-distortion technology(3), which already has a proven track record in 3G systems, making this base station among the world’s most efficient.

While delivering high-power, high-capacity data transmissions with two high-output transceivers, the unit is the world's smallest outdoor macrocell base station, with a weight of approximately 20 kilograms and volume of 20 liters. By combining world-class energy efficiency with the world's smallest base station enclosure, Fujitsu has significantly reduced the costs associated with installing and operating base stations, thereby contributing to the global deployment of mobile WiMAX infrastructure.


  • [1] the smallest base station in its class

    The WX300 is the smallest among all-in-one base stations which incorporate the wireless transceiver, wireless signal processor, media converter, GPS receiver, and power supply in a single enclosure. Based on Fujitsu research as of February 6, 2008.

  • [2] Gallium-nitride High Electron Mobility Transistor (HEMT)

    Gallium nitride (GaN) semiconductors are more resistant to breakdown at a given voltage than conventional semiconductors, such as silicon or gallium arsenide, a characteristic that gives them higher electrical efficiency and enables them to be driven at higher voltages, for high-speed data processing, when used in a HEMT structure.

  • [3] Digital pre-distortion (DPD) technology

    Technology that adds an input signal with the opposite characteristics to the distortion generated in an amplifier, thereby correcting the distortion in advance.
