PipingHot Networks (PHN) recently completed its first live field trials of the company's Broadband Wireless Internet Forum (BWIF) compliant non-line-of-sight (NLOS) wireless 3.5 GHz system, using open standard technologies.
Additionally, Vyyo Inc. recently revealed its strategy for migrating its standards-based enhanced DOCSIS platform to NLOS fixed-broadband wireless systems. Vyyo said its NLOS systems will first be implemented in the MMDS and 3.5 GHz frequency bands.
PipingHot Networks' 3.5 GHz NLOS system delivers high-speed wireless access to a number of sites, including the company's recently opened customer demonstration site, as well as providing a local college with a 22-Mbps, always-on Internet connection.
The company's Broadband Fixed Wireless Access solution, which is based on the BWIF standards, has advantages over other methods of broadband provision in that it enables operators to deploy fully managed IP based services to enhance differentiation from the incumbent operator, according to the company. Broadband wireless also avoids the costs and planning difficulties of laying wires and cables required by alternative systems.
BWIF is dedicated to deregulation of the fixed wireless equipment market in order to bring the benefits of an open standard to the operators.
Both line-of-sight and NLOS conditions were tested in the PHN trials, with NLOS transmissions being achieved over a distance of 2.5 km.
