UQ Communications Inc., a nationwide Japanese telecommunications carrier capitalizing on mobile WiMAX technologies, has selected NEC Corp. to supply mobile WiMAX base stations. The company has chosen to adopt NEC's recently developed Paso-Wings BS202 mobile WiMAX base station, which is the first to be equipped with Uplink-Beam Forming (UL-BF) technologies. These technologies improve communications speed and increase the base station coverage area by reducing radio frequency interference between base stations and data transmission terminals.

The system's adoption follows NEC's work to acquire the WiMAX Forum's Wave 2 (2.5 GHz, 3.5 GHz) authentication and its actions to secure international standardization. A wide variety of functions and an external interface based on international standards enable the PasoWings BS202 system to be integrated with a broad range of vendors' equipment, which contributes to the smooth construction of WiMAX networks in short periods of time.
The base stations are compact and the adoption of a high efficiency amplifier enables the integration of outdoor units (ODU), which send and receive transmissions, with indoor units (IDU), which convert signals and control access. Also, reducing the space required to accommodate base stations, the time needed to construct them, and the resources necessary for maintenance reduces costs. NEC regards its selection to provide the PasoWings BS202 to UQ Communications as evidence of the high regard held for its products and services on a worldwide level.
