Speaking of wireless

Edward Wyatt has an article in Tne New York Times about the latest moves by the FCC:
The Federal Communications Commission approved a proposal that would open vast amounts of unused broadcast television airwaves for high-speed wireless broadband networks and other unlicensed applications.
The change in available airwaves, which were freed up by the conversion of television signals from analog to digital, constitutes the first significant block of spectrum made available for unlicensed use by the FCC in twenty years.
It was a victory that did not come easily, or quickly, however. The FCC first approved a similar measure in 2008, but the technical requirements for unlicensed devices drew objections from seventeen companies or groups on both sides of the issue, forcing the commission to redraft its proposal. While computer and Internet companies like Google, Microsoft, and Dell favored the idea, television broadcasters worried about possible interference problems.
The new order eliminates a requirement that devices scan the airwaves for available signals. Rather, they can rely on a database of digital signals, updated daily, for use in locating an available channel on which to transmit. The order also contains provisions that seek to guarantee that wireless microphones have adequate space to operate without interference.
Supporters of the measure hope the airwaves will be used for stronger and faster wireless networks— known as “super WiFi” because of the signals’ ability to pass more easily through obstacles— and for use in providing Internet access to rural areas.
“Today’s order finally sets the stage for the next generation of wireless technologies to emerge and is an important victory for Internet users across the country,” Richard Whitt, telecommunications and media counsel in Google’s Washington office, said in a posting on the company’s public policy blog.
Though unlicensed airwaves have been used for decades in applications like garage-door openers, cordless phones, and, most recently, Wi-Fi networks, the newly available signals are stronger and therefore offer greater opportunities for engineers and entrepreneurs, supporters say.
But potential problems abound. Many urban areas, including New York, have so many operating broadcast TV stations that unused space is relatively rare. Broadcasters objected to some of the FCC’s proposals, fearing that unlicensed devices would interfere with their station signals.
Michael J. Copps, an FCC commissioner who has been a longtime advocate of freeing up the unlicensed airwaves, known as “white space”, said that he expected technology companies would now find ways to overcome those obstacles.
“One of the great lessons that I quickly learned here at the FCC is the power of technology to turn scarcity into abundance,” Mr. Copps said. “I look forward to seeing new devices widely available in consumer markets next year.”
The FCC also approved changes to the E-Rate program, which provides federal money to pay for Internet connections at schools and libraries. The new rules will allow them to set up Internet connections that use the currently dormant fiber-optic lines that are already in place in many communities, giving users more options and theoretically bringing down the cost of Internet service. The new E-Rate rules also will allow schools to provide Internet access to their communities after students go home in the evenings, further expanding broadband availability. The FCC also voted in favor of an E-Rate pilot program to explore off-campus wireless Internet connections for mobile learning devices, a practice that Julius Genachowski, the FCC chairman, said would open the way to digital textbooks.
The commission also approved measures that it thinks will help improve the ability of emergency call centers to better locate people who call 911 from wireless phones.
Rico says he looks forward to 'Super WiFi'...
