  • Congress passes bill opening up TV spectrum to next-gen WiFi networks

    It may seem a bit odd to see tech industry groups like the CTIA and CEA praising the passage of the Temporary Payroll Tax Cut Continuation Act of 2011 by Congress, but that rather mundane-sounding bill has provisions attached to it that both groups and others have been pushing for years to happen. In an effort to cover the cost of the payroll tax extension, the bill also sets aside a large block of so-called unlicensed spectrum for auction, which is expected to bring in upwards of $25 billion. That spectrum had previously been used for TV broadcast use, but is now being eyed by various parties for next-generation WiFi networks, which could cover greater distances and potentially be used to bolster existing wireless networks. As part of the bill, Congress has also set aside a slice of spectrum that will be used as part of a nationwide network for public safety agencies. As The New York Times notes, however, it will see be quite a while before anything trickles down to consumers, with the auctions themselves at least a year or two away. The CEA and CTIA's statements can be found after the break.[Tower photo via Shutterstock]

  • CSIRO looks to analog TV spectrum for 100Mbit wireless broadband

    Australia has already rolled out its plans to bring high-speed broadband to 90% of the country's population via fiber optic lines, and it looks like the folks at CSIRO are now pitching in with some ideas of their own to bring speedy wireless broadband to that ever present "last mile," and anyone else looking for an extra wireless option. As with others, they're looking to take advantage of all the analog TV broadcast towers that'll become available once the digital switchover in the country is complete, and it seems that they also have a few tricks up their sleeves that could eventually deliver wireless speeds up to 100Mbit per second (though it'd apparently be between 12 and 50 megabits per second initially). To reach those speeds, the group is apparently experimenting with a combination of orthogonal frequency division multiplexing (or OFDM), used in basic wireless standards like 802.11g, and multiple input multiple output technology, or MIMO, which uses a range of antennas to transmit and receive multiple data streams. Of course, there's still quite a bit of work to be done before any of that moves beyond the lab, but CSIRO says that field trials could begin in 12 to 24 months, with a commercial rollout possible in the next three to five years.[Thanks, Aaron]

  • 700MHz band: future home to worldwide mobile broadband standard

    If you've been losing sleep over not knowing precisely what was going to happen to all that spectrum space that will be freed up when the imminent analog-to-digital cutover takes place, your insomnia is about to be (at least partially) cured. The US of A apparently pushed hard for a worldwide consensus on spectrum use -- suggesting that a common approach was more reasonable than each nation choosing separate frequencies for next-generation services -- and sure enough, it ended up getting exactly what it wanted. Apparently, the 700MHz band will now be reserved for a mobile broadband standard accessible throughout much of the globe, including most of North America, Central America, South America, Europe, China, India, South Korea and Japan. Of note, Europe was able to land a concession that enables it to offer up "about half of the bandwidth available for mobile services in their region" compared to what is offered elsewhere, but the agreement definitely makes the forthcoming auction that much more interesting.[Via RCRNews, image courtesy of toddemslie]
