FCC Will Test Internet Over TV Airwaves, Again 86

Weather Storm writes "According to MSNBC.com, the FCC will try again to test prototypes on Jan. 24 for transmitting high-speed Internet service over unused television airwaves. The devices were developed by Microsoft and Motorola, among other corporate partners, and will be tested in laboratory and real-world conditions for three months. 'Last year, a high-technology coalition — which included Microsoft, Google Inc., Dell Inc., Hewlett-Packard Co., Intel Corp. among others — submitted prototypes they said could transmit broadband Internet service over unlicensed and unused TV spectrum, known as "white spaces." Television broadcasters and the wireless microphone industry say such devices could interfere with programming. The Initial prototype testing failed last July because the devices did not reliably detect and avoid TV programming signals and could have caused interference. If the tests are successful this time and the devices are approved, the coalition plans to introduce commercial devices for sale after the digital television transition in February 2009.'"

    That's a really neat idea. If properly implemented, that would significantly expand wireless internet coverage to just about anywhere in the nation. It would definitely help for people who travel a lot. Still, the initial test failures such as not recognizing normal TV signals makes me wonder. If they could figure out how to properly detect regular TV and avoid it, this could be a definite advance in connectivity.

    I wish there was more information about all of this. Specifically, I wish the FCC would be able to give us a template for the upcoming changes to all forms of bandwidth and how they are intended to be used in the future.

    I remember something a fear years ago about the switch to HDTV somehow opening up a range frequencies on the FM dial, and the FCC talking about maybe loosening restrictions on licensing for broadcast in the FM spectrum. I haven't re-heard any of that since.

    I also remember, while I was studying the use of power lines as FM transmitters (apparently the signal is periodically flattened, though, by the transformers), the FCC mentioning something about using the power lines to double as internet. This was just after the DSL market leveled off, I remember. Anyways, there was a lot of talk about how to get that done, and special switches to go around transformers, or something. I haven't re-heard any of that, either.

    I never liked DSL, btw. It seemed like the public was being duped into agreeing that they have no business using modems that fast without paying the phone companies for compensation. That's my impression based on the way the phone companies handled 14.4s and 28.8s. With 14.4s they started saying "you need to tell us if you are using your phone line for data communications; there's an extra fee." They tried to justify that by saying the fee paid for keeping the line more free of noise, which simply wasn't true. I remember a number of SysOps actually letting the phone companies know they were running BBSs off their low-calling-plan phone lines: they still had just as many checksum errors as they ever did, usually because they lived in the rural areas. Then when 28.8s came out, the phone companies started it all over again, except this time their gripe was that the higher throughput was a drain on the company's resources and they needed proper compensation, and threatened that if they found anybody was using their phone line for data without telling them, they would automatically flip you into the higher-paying mode. My impression then was that enough businesses and day-traders had told the company they were using their lines for data and ponied up the extra charge, but found that their signal wasn't any less noisy than usual, and got pissed and complained. Anyways, then DSL came out, and it was the same thing all over again, except that this time the phone companies had the jump on the technology and the right to use it on their lines. They were especially tight-fisted with who's allowed to so much as own a DSL modem, or if they couldn't manage to monopolize that market they were working out exchanges that required the company's leased and serialed modems. I have a question about that; when everybody's onto coaxial and the phone lines aren't being used for data any more, what will all of the "extra bandwidth" there be used for? Not voice: too many people are using cellphones for even their most casual home use, it's just more practical. What good will the phone lines be to us once they aren't getting used?

    About the TV band again. I started reading up on it and learned that Japan had gone digital TV quite some time ago, but was still using the same airspace; they just managed to use compression to fit around two digital channels into the same bandwidth as one of our analogues. Why didn't America ever go into that same system, given how much Americans love both television and varieties? It seemed obvious to me, some time later, that twice as many channels are twice as hard to corner and monopolise. Some may say that deals couldn't be worked out so that manufacturers believed Americans would go out and buy replacement sets; but I still say any deal with a lucrative outcome eventually gets made by somebody, and it was simply obviously more lucrative to keep things tight-gripped rather than allow the market to be widened. We still have our "Big 3" today even though things have changed oh-so-much; when the hell are those disinfo mouthpieces going to fail and just go away?

    I hope I am wrong about this, but if the internet gets transmitted over TV airwaves, wouldn't the FCC automatically gain authority to censor anything they dislike or dictate is 'offensive' -- just like they do with television and radio in America?

    I work in this field for one of the corporations involved in this work with the FCC, and am involved in cognitve radio for TVWS work. If you do a search of the internet using the phrase "cognitive radio" you will get a better idea for how the systems will work. There will be lots of small access points (initial generations of the systems will be about the size of a cigar box). Mobile stations (endpoints such as phones) will function in one of two modes, either tethered or in peer-to-peer.

    The trick to make it work cleanly is geo-location information being available to the devices (mobile stations, access points, et cetera) and a map/database of known (authorized) transmitters in the TVWS frequency range in the areas. Its also highly likely that policy-based management and autonomics will come into play to control the mobile stations and the access points.

    This is a big deal folks, it will revolutionize the way we comunicate and interact with each other and world around us. Look for papers authored by Joseph Mitola (DARPA Scientist who coined the phrase "cognitive radio") -- the guy is truly a visionary.

    Have you ever looked at the TV reception issues in an area like Alaska? That's some fun.

    There are parts of the rural mountainous US where you have to use a 10' satellite dish to get anything, and that's from local channels that are rebroadcast off of satellite. There's an old joke that the state bird of West Virginia is the C-band satellite dish.

    Yep - Alltel - their voice packages are a bit higher than their competitors - by about ten or fifteen bucks a month - but their service does have this great advantage of working - even in remote, rural areas.

    Have you priced out just fixing the problem by buying a real connection?

    T1 lines are damn cheap now - I frequently see prices around $400/month. Optical lines start in the low thousands. All it would take is a couple neighbors and setting up a WiFi or even DSL co-op becomes competitive with what you'd expect DSL/Cable to cost.

    Now, that may not be the right answer for getting internet access occasionally at your parents house - but it absolutely is for anyone personally lives somewhere where the telcos won't provide service (or won't provide good service).

    This system will work decently. Spread spectrum radio is common today in your cell phone, your wireless house phone, and every wifi card everywhere. the concept of a defined frequency for a defined service is on the way out. Much like DC electricity, it was used for a lot of reasons, but as time goes on, a smart radio system will become common. The six megahertz needed for an analog signal is today like using a steam engine for commuter rail. You can do it, and it works, but it's not a clean or simple solution. With the advent of microchips and strict time sequences, cognitive radio is an easy deal. It also solves the problems of too many users for a limited amount of discrete frequencies. the idea of frequency allocation is because up until now, you could only be one per frequency. The prime real estate was given to TV way, way back when. It is no longer 1940. TV has some interference issues when the band opens, but you are dealing with megawatt transmitters in prime locations...I can get Philly when conditions are right here in NYC, but that's not "the market". Leaving the white spaces unused is like deciding that Ohio can't grow corn because Wisconsin is.

Work without a vision is slavery, Vision without work is a pipe dream, But vision with work is the hope of the world.
