Fujitsu Announces Global Launch of Mobile WiMAX Base Stations
Posted: 06-Feb-2008 [Source: Fujitsu]

[Fujitsu announces the compact outdoor BroadOne WX series of mobile WiMAX base stations--the smallest in its class.]

Tokyo -- Fujitsu Limited announced today the development of the BroadOne(TM) WX series of mobile WiMAX[1] base stations. The BroadOne WX300, an outdoor macrocell base station, is light, energy-efficient, and - as the smallest in its class[2] - occupies less space, which makes it economical to deploy. The BroadOne WX300 will be available globally beginning in the second quarter of 2008 (April-June).

Fujitsu is positioning the BroadOne WX series mobile WiMAX base stations as a key part of its global product solutions for the rapidly emerging wireless broadband industry. Wireless broadband is widely expected to transform the way people live and work in the next-generation network era, as it promises high-speed, high-capacity connectivity to everyone, everywhere.

Fujitsu has designed its new base stations with many features to meet the global requirements for mobile WiMAX networks. The base stations consume low levels of power, deliver superior performance, and, as the smallest base stations available, are easy to install. As a result, mobile WiMAX service providers will be able to build their wireless broadband infrastructure at a lower cost and offer end-users service at more reasonable rates.

With the launch of the base stations, Fujitsu is also introducing its BroadOne brand name to be used for forthcoming wireless products.

The BroadOne Mobile Base Station Series

Fujitsu plans to provide three new base station models designed for the 2.5GHz and 2.3GHz frequency bands. Configured as a single, lightweight unit, the BroadOne WX300 outdoor macrocell base station is designed for wide-area transmission over a radius of several kilometers. The WX300 model will be the first in the base station series to go on sale, with global delivery in the second quarter of 2008. The second model, a compact outdoor microcell base station, is designed for transmission over a several-hundred-meter radius to fill in areas with a lower concentration of users and remote areas with poor coverage. The third model is an indoor, ultra-compact picocell base station.

With these models, Fujitsu will provide mobile broadband solutions for all types of environments and needs.

Features of the BroadOne WX300 Macrocell Base Station

The new BroadOne WX300 outdoor macro base station features world-class efficiency and performance. The unit's high-output transmitter (amp) uses a gallium-nitride (GaN) High Electron Mobility Transistor (HEMT) device([3] that was developed based on ultra-high-speed transistor technology invented by Fujitsu. This device is coupled with Fujitsu digital pre-distortion technology[4], which already has a proven track record in 3G systems, to create two high-output transceivers packaged in a single unit. With a weight of approximately 20 kilograms and volume of 20 liters, the unit is the world's smallest outdoor macrocell base station.

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. Details of the product will be presented next week at Fujitsu Microelectronics Europe's stand 1J45 in Hall 1 of the GSMA Mobile World Congress 2008 from February 11-14, 2008, in Barcelona, Spain.

The Fujitsu Alliance with Airspan Networks

Fujitsu recently entered into an alliance with Airspan Networks, a company with a global track record in the WiMAX market. Under this agreement, Fujitsu and Airspan will share technology and resell each others' products to offer customers a complete product line and better meet the needs of WiMAX providers.

The BroadOne Brand of Wireless Broadband Products

With the launch of the BroadOne WX300 mobile WiMAX base station, Fujitsu is unveiling its new BroadOne brand name, which covers an integrated series of base stations and other products for the "Long Term Evolution" (LTE) project under which next-generation mobile phone systems will be developed for the rapidly emerging wireless broadband market.

The BroadOne brand name was chosen to reflect the Fujitsu advanced technologies that will enable wireless networks around the world. By bringing easy-to-use networking to as broad a segment of people as possible, Fujitsu aims to become the number one vendor of wireless networking equipment.

[1] Mobile WiMAX: IEEE802.16e-2005-compliant mobile wireless standard.

[2] Smallest in 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.

[3] Gallium-nitride High Electron Mobility Transistor (HEMT): An ultra-fast field-effect transistor pioneered by Fujitsu in 1980. Gallium nitride (GaN) semiconductors are more resistant to breakdown at a given voltage than conventional semiconductors, such as silicon or gallium arsenide. The HEMT structure enables high-voltage, high-speed data processing.

[4] 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.
