FCC opens unused TV band to wireless devices

Beijing Time September 24 news, according to foreign media reports, the United States regulatory authorities local time in Thursday decided to open the idle TV band to mobile broadband use, thus paving the way for the development of fast-growing new wireless devices. The Federal Communications Commission (FCC) unanimously approved the decision to allow unlicensed wireless devices to be used on idle television frequencies.　　Equipment manufacturers such as Dell, Nokia and Motorola will benefit from this.　　Julies Gnakoski Julius Genachowski, FCC chairman, said it was the first time in 25 years that the FCC had released the unlicensed band (unlicensed spectrum). "This new unlicensed band will be a powerful innovation platform. As we have seen again and again, when we unleash American creativity, great things happen.　　"he said.　　These channels, called Blank spaces (White MSN), were released in the 2009 analog to digital TV conversion, consisting mainly of gaps between current broadcast channels.　　Compared with the spectrum currently used in Wi-Fi, these spectra have the characteristics of faster signal transmission, more penetrating of walls, and wider coverage of the area. Some technology companies have been in the water hoping to deploy new super Wi-Fi systems.　　Use these channels to make it easier for families, companies, schools, and municipal facilities to surf the Internet faster and to improve connectivity for mobile devices.　　Broadcasters had feared that the use would disrupt their channels, especially those used by the wireless microphones they used to cover.　　The FCC has clarified the conditions for using these unlicensed channels to resolve such problems, including requiring devices using a blank space channel to access a database to determine which frequencies are available at a particular location. The department also said that two television channels would be retained for the wireless microphone, which would allow 12 to 16 microphones to be used at the same time without interference.　　In some special situations, such as large competitions, where more resources are needed to use the microphone, a case application can be taken.　　The successful business of the space band is expected to take at least 1.5 to two years, as network operators, chip makers and equipment makers also need to form industry standards. Gnakoski quoted an analyst as saying that the space band would be a 7 billion dollar industry. (Kevin)
