Fujitsu Launches "BroadOne" Mobile WiMAX Base Station

Fujitsu Network Communications introduced its "BroadOne" WX series of mobile WiMAX base stations designed for rapid installation and high-power output and global spectrum requirements. Fujitsu said its new base stations are designed to consume low levels of power while being small and light enough to be carried by a single technician during installation. This allows mobile WiMAX service providers to build and operate their wireless broadband infrastructure at a lower cost.


Fujitsu plans to provide three base station models designed for the 2.5 GHz and 2.3 GHz frequency bands.


The first model is the BroadOne WX300 outdoor macrocell base station which is configured as a single, lightweight unit and is designed for wide-area transmission over a radius of almost two miles. The unit's high-output amplifier uses a gallium-nitride (GaN) High Electron Mobility Transistor (HEMT) device that was developed based on Fujitsu's ultra-high-speed transistor technology. This device is coupled with Fujitsu digital pre-distortion technology, which is currently used in 3G systems, to create two high-output power transceivers packaged in a single unit. Fujitsu said its use of advanced amplifier technology allows the base station to weigh approximately 40 pounds, enabling tower, pole or building top installation by a single person. The unit accepts AC or -48 VDC power input with either optical or copper Ethernet network connectivity.


The second model, a compact outdoor microcell base station, is designed for transmission over a nearly 1,000 foot 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. All base stations will support Multiple Input Multiple Output (MIMO) technology operating in both Matrix A and B to improve system performance. With these models, Fujitsu will provide mobile broadband solutions for all types of environments and needs.


Fujitsu Network Life Cycle Services are available to help network operators with RF engineering, site acquisition and site preparation. When network operators are ready to build their network, Fujitsu offers a full line of deployment services, which include installation and test/turn-up services, as well as backhaul and back-office connectivity provisioning. Carriers can also opt to have Fujitsu monitor and maintain their wireless network with Network Operations Center (NOC) services and provide network statistics so operators can have full visibility to the inner workings of their network. Full maintenance and support is also available 24x7, with rapid deployment of on-site technical assistance personnel and spares management as needed.http://www.fujitsu.com/us/services/telecom/categ/wirelesstransport
