Why We Need Unlicensed White-Space Broadband Spectrum 179

Posted by timothy
from the 50,000-watt-internet-stations-at-the-border dept.
pgoldtho writes "PC Mag has a story about why the 'white-space' spectrum that will be freed when TV broadcasts switch to digital should be available for unlicensed use. This would allow it to be used to deliver broadband connectivity in rural areas and create a 'third pipe' alternative to the cable/telco duopoly. The FCC is scheduled to vote on this November 4th. The National Association of Broadcasters (NAB) has filed an emergency appeal to block this vote. If the NAB succeeds, the issue will be kicked into next year. Which would mean a new FCC, Congress, and Administration."

    Forget about it. If there's money to be made, someone's got a sniff of it and they're already lobbying harder than you ever could. (For 'harder' see 'with more assets'.)

    And even if it stands that the space will not be licensed for some other commercial use, the existing bandwidth owners will lobby against it ever being given back to the public, because there is money to be made fencing people in to their existing ownership of the spectrum.

    The very idea that the electromagnetic spectrum can be fenced off strikes me as ridiculous. Don't get me wrong - I'm aware of why it needs to be done. But it seems like such a short jump from there to Coca Cola declaring all rights over 'red'.

          It's good to hear that the FCC is so attuned to the problems of RFI and TVI. Otherwise I'd be really worried about the practice in the Deep South where right-wing broadcasters manage to license frequencies adjacent to NPR stations, and effectively drown them off the air. Since the FCC is so concerned, of course they're going to address this.

At say 5 watts (whatever/small) for the home connection "last mile" rig, will this work over long distances with hills and trees, or will it be line of sight and not much better than current wifi?

      The issue of power, distance and line-of-sight are all things that are actually big parts of the debate on this.

      For instance, if your internet device is in a valley between two hills, and a TV tower is broadcasting on one hill, with a tv viewer on the other, your device may not be able to determine that they're broadcasting there.

      The net result is crap internet for you and you've annihilated the TV signal for the person viewing it on the other side of the valley.

      The lower frequency will give you a much better chance than current WiFi frequencies, but it will be fairly short range (last mile, not across the state).

A few hills will be fine, but large granite faces will be a problem still.

    While I love the idea of free and open internet communication (unlikely if we farm this out to Google and Microsoft), if they plan on using the performances they've seen in FCC tests as the benchmark, you can expect even your cable TV to cut out. I absolutely love the concept, but the simple fact is that current versions of these devices don't work, and Kevin Martin is for sale [wikipedia.org].

    I'd put $50 on him ending up at Google or Microsoft within a year of leaving the FCC. Anyone who talks with the people who were at the white-space device tests knows that these devices failed miserably.

    1) Spectrum being freed up.

    No. No spectrum is freed up by switching from analog to digital. A digital station takes up 6Mhz, same as an analog station. It's true that the FCC has relaxed adjacent channel restrictions, but any spectrum freed by that is balanced by the loss of channels 52-69, which have already been auctioned off. There's no truly free high-VHF or UHF slot between New York and Baltimore; spectrum's full.

    2) WSDs being able to detect stations

    For a WSD to reliably detect another transmitter, it would have to be as sensitive and have as good an antenna as the intended reciever. What are the chances of that, particularly in a portable device? Sure, your little iAndroZune with its 2" stub can't detect the channel, but my purpose-built TV tuner with a 10dBi antenna could pick it up fine... or it could, until the iAndroZune started stepping all over it.

    3) Won't interfere even assuming it finds a white space
    The front-end filters on TV tuners have about a 5-channel passband. A strong signal anywhere in there can cause the RF amp to overload or force the AGC to cut in and thus desensitize the tuner. One of the FCCs own studies showed it could be cause up to 70dB of sensitivity loss on adjecent channels, which makes the difference between very good reception and none at all. Furthermore, those of us using a pre-amp to receive weaker stations don't have the benefit of front-end filtering; a white space device anywhere in the band can cause problems throughout the band. Note that some of those little USB stick tuners don't have front-end filtering either.

  • There are very good reasons to allow public use of white space. Internet access prices should drop, wifi should become more widespread, and there's the tasty idea of mobile phone calls (at least local) becoming FREE, since they will communicate *directly* with each other.

    Google are in fact in favour, and have created a website here [freetheairwaves.org]. They sum it up pretty well.
