Carlson and Neul have hit the market with a networking system designed for wireless Internet service providers (WISPs) looking to provide broadband using white spaces.

The Neul and Carlson system, called RuralConnect, is designed to provide up to 16 Mbps of bandwidth for each available vacant TV channel in the UHF spectrum – so-called “white space.”

The UHF spectrum is desirable because of its strong propagation properties, but transmissions in this frequency range can also become subject to multipath interference. The RuralConnect uses SCFDE (single carrier frequency domain equalization) to cancel the effect of multipath.

The significance, the two companies said, is that service providers deploying a network operating on white space frequencies can do so with fewer base stations than might be needed for systems operating at other frequencies and still get excellent geographical coverage.

Depending on the area, up to 20 channels are available, increasing the amount of non-line-of-sight-capable spectrum available by a factor of 10, Carlson and Neul said.

Concurrently, Carlson is launching a line of omnidirectional and sectoral high-gain base station antennas designed specifically for TV white space broadband.

Luke D’Arcy, vice president of marketing at Neul, said: “The outstanding propagation characteristics of white space signals means that operators can serve customers they cannot reach with existing wireless technology. The capacity available allows pioneering WISPs to offer all customers faster plans that beat ADSL-based competition. And this is possible without investing in new tower sites, spectrum licenses or high-priced network equipment, boosting profitable growth.”

Samples and development kits for RuralConnect are available now, with volume shipments of the new system to start as soon as Q2 2012.
