The first broadband on telechastotah
Yesterday in the town of Claudville, pc. Virginia, earned the world's first open broadband network, operating at radio frequencies in the free range of the television spectrum, that is, in the sections between television channels ( white spaces ).
The network is launched on the Spectrum Bridge technology, this company maintains a database of free radio frequencies, which contains information about hundreds of TV channels.
The use of telefrequencies is an excellent and, perhaps, the only possibility to deploy a broadband radio communication network on a national scale, because nature has not left us with other parts of the spectrum in such a wide range. On TV, you can provide more speed and range of communication than conventional WiFi, which is why new technology is sometimes called WiFi on steroids .
Of course, representatives of the television industry are categorically unwilling to share frequencies. They assure that when traffic is transmitted, interference occurs and signal quality deteriorates at the main frequencies. But technology does not stand still, and new radio modems work much cleaner. Microsoft, Google, Intel and a number of other representatives of the IT industry are in favor of selecting parts of the television spectrum. In November 2008, the new standard was approved by the FCC, subject to the use of modems with a capacity of up to 100 mW in the unlicensed spectrum and up to 40 mW in the spectrum near TV channels.
