wireless vocal microphone Google asks FCC for access to TV 'white space'
Google on Monday called on the federal government to open up unused parts of the radio and television spectrum to compare Wi-Fi.In a six-In a letter to the Federal Communications Commission, Google promoted plans for unlicensed and unused spectrum, called television "blank", and tried to mitigate the interference with broadcasters and wireless microphone users.Google lawyer Rick Whitt has urged the FCC to pass the rules that allow devices to take advantage of the gaps, saying it is a valuable resource that is heavily underutilized."The unique quality of TV blank space --Unused spectrum, lots of bandwidth, and excellent propagation features-offer a once-in-a-Provide lifelong access to ubiquitous wireless broadband for all Americans, "Whitt wrote.Whitt said Google's latest push has nothing to do with the latest FCC 700Hertz spectrum auction ended last week.Google, the main competitor to the auction, was eventually defeated by Verizon Wireless for the most expensive spectrum available for nationwide Wireless networks.The purpose of this letter is more to address the problem of interference with the use of blank space, which hinders the approval of the use of blank space by federal regulators.Last year, for example, the FCC delayed the approval of white space after testing to find equipment using the spectrum interfering with or failing to avoid TV signals.Whitt presents a range of techniques and methods in the letter to ensure that TV signals are not blocked.Whitt believes that by using Motorola's "spectrum sensing" technology and Google's new protocol to ensure that blank devices do not interfere with TV signals, spectrum can be used without conflict.He also proposed a "safe harbor" for wireless microphones covering several channels, banning the use of the spectrum by blank space devices.However, critics are not interested in Google's protection measures.Dennis Walton, executive vice president of the National Broadcasting Association, said Google's latest efforts failed to ensure that interference was completely eliminated.Wharton said in a statement: "portable mobile personal devices operating in the same band as TV broadcasts are still a guaranteed formula for generating interference and should not be allowed under any circumstances.Google is just one of the many heavyweight blank users, including Microsoft and HP.HP, Dell, Intel and others.But Google has always been one of the biggest supporters of wireless broadband.Not only did the company bid 700-MHz spectrum, but also managed to attach rules to ensure that the winner Verizon Wireless allows the use of any device or application on newly purchased airwaves.Google is also developing a mobile operating system called Android, which may run on multiple cellular networks.Together, these initiatives ensure that users can access Google content and applications from an increasing number of Internet users.Connected mobile devices.While the plan will certainly help Google, it will also create opportunities for more wireless competition, which may reduce the cost of mobile broadband for consumers, Whitter said.It will ensure that other content providers are free to reach consumers."We want us to be on the consumer side," Whitt said on Monday ."."Things that work well for us also work well for consumers so that they can access not only from us, but from the internet anything they want.
