WiMAX base stations to run Linux

PureWave Networks is using Linux, a Freescale processor, and an off-the-shelf middleware package from Enea to create its next generation of WiMAX base stations. Due later this year, the base stations will aim to bridge the gap between macro and pico WiMAX stations, says the company.
The PureWave WiMAX/LTE base stations will combine the functionality of a traditional macro base station with the small footprint and lower pricing of pico base stations, claims PureWave. Designed for outdoor installations, the base stations will be mountable on towers, poles, or walls, says the company.
The base stations are said to incorporate adaptive beamforming technology that optimizes spectral efficiency, data throughput, and range. Beamforming is a signal processing technique used by sensor arrays to offer directional signal transmission or reception, and adaptive beamforming is said to better adapt to different transmission conditions.
The small form-factor systems are based on an undisclosed Freescale processor, and use a Freescale Linux distribution, which the company expects will ship with a Linux 2.6.24 kernel. The design may well incorporate Freescale's multi-core, PowerPC-based PowerQuicc III "MPCxxxx" networking processors, or else its new PowerQuicc heir, the QorIQ.
WiMAX on the cusp?
Slow to emerge, WiMAX appears to have finally gotten off the ground in the U.S., with the launch of Clearwire's first WiMAX deployments and merger with Sprint Nextel's WiMAX efforts under the Clearwire name. Most recently, Clearwire launched a 4G "Clear" service in Portland. However, with the current tough economy, Clearwire has its work cut out for it in building the network nationwide. Other nations -- especially India -- seem to be moving forward aggressively with WiMAX.
Meanwhile, the USDA (Department of Agriculture) last March awarded $267M to Colorado-based Open Range Communications to use WiMAX how it was originally intended -- to extend broadband into rural areas. Private investors piled on another $374M a few months later. The group hopes to deliver WiMAX in 17 states, including California, Nevada, Colorado, Nebraska, Arkansas, Wisconsin, Illinois, Indiana, Ohio, Pennsylvania, New York, New Jersey, Delaware, Alabama, Georgia, South Carolina, and Florida.
