(Telecompaper) Carlson Wireless announced the launch of the first TV White Space (TVWS) trial in South Africa. Led by Google, the trial will test TVWS wireless broadband in ten schools across the Cape Town area. Carlson, the project's equipment vendor, Google and other project partners will attempt to show that broadband can be offered over white spaces without interfering with licensed spectrum holders. To prevent interference with other channels, the network uses Google's spectrum database to determine white space availability. Carlson's RuralConnect Broadband Solution, enabled by the Neul Horizon software, provides the communications backbone for the trial. TV White Spaces' lower frequencies can travel longer distances, making the technology well suited to provide low cost connectivity to rural communities with poor telecommunications infrastructure. It is also used for expanding coverage of wireless broadband in densely populated urban areas.
