  • Lucky residents of Wilmington, N.C., will be the first in the nation to have access to a "Super Wi-Fi" network.

    Officials from New Hanover County, N.C., announced today that they had become the first in the United States to deploy a mobile data network on so-called "white spaces" spectrum that the Federal Communications Commission first authorized for unlicensed use in 2008. The county was able to make a quick transition in using the spectrum for a mobile data network because it was the first to successfully transition from analog to digital television.

  • "Super Wi-Fi" is essentially a buzzword created by the FCC to describe mobile data networks that run over the white spaces spectrum. The spectrum band's low frequency allows for signals to travel farther and penetrate more walls than traditional Wi-Fi networks.

AT&T T-Mobile antitrust mergers spectrum wireless networking

  • AT&T said on Monday afternoon that it had withdrawn its $39 billion takeover bid for T-Mobile USA, acknowledging that it could not overcome opposition from the Obama administration to creating the nation’s biggest cellphone service provider.

    The company said in a statement that it would continue to invest in wireless spectrum, but could not overcome resistance from both the Justice Department and the Federal Communications Commission.

  • Under the terms of the deal, AT&T will pay Deutsche Telekom $4 billion in cash and wireless spectrum as a break-up fee, and the two companies will begin a seven-year roaming agreement that will expand T-Mobile’s national coverage.

802.22M standards wireless networking white space

shared by Paul Merrell on 29 Jul 11 - No Cached
  • The unique nature of the spectrum makes designing networking algorithms and protocols a challenge. There are several digital TV white spaces in the band, and the demands of access points vary over time. "Since in a TV band you don’t get continuous contiguous spectrum—a typical white-space chunk has 6 MHz—you need at least two radios to tune to different bandwidths. Our algorithms decide which radio will choose which bandwidth," says Srinivasan.

802.22M standards wireless networking white space

shared by Paul Merrell on 29 Jul 11 - No Cached
  • The 802.22TM-2011 standard will be used on frequencies that were used by analog television channels, but were freed up when the U.S. transitioned to digital television broadcasting over the air. Known as “white spaces” technology, the wireless standard supports transmissions speeds topping out at 22 Mbps per channel, with a range of up to 100 kilometers.
  • Unlike the frequencies used by cellular network operators, the white spaces use unlicensed spectrum (just like today’s Wi-Fi networks), so a wide range of compatible devices are expected from many companies. This would make it far easier and cheaper for those in remote areas to gain faster Internet access, for example.
  • For more details on the potential uses of white-spaces, see our recent “everything you need to know” article.
