White Space Plan Would Reuse TV Spectrum
An anonymous reader writes "A collection of companies including Microsoft, Google and Motorola are teaming up for a new white space wireless network plan. The White Spaces Database Group, as it will be known, plans on formulating a plan to create, govern and maintain a wireless broadband network on abandoned analog television spectrum. When the spectrum is finally vacated in June, the group hopes that system in place which will allow for the creation of an open wireless broadband network which will be accessible by any device. The FCC officially approved keeping the spectrum open back in November, despite staunch opposition from telco firms."
Why you being racist like that? Do whites really need more space? Don't they have enough already?
What? you want any large corporation to just be able to take it all for themselves?
That's really the other choice. Govern it, or let the biggest bully take it.

This is a very profound threat to lucrative mobile cartels. Yet it's absolutely necessary as a step on the way to opening the airwaves to serve a real global Internet. My prediction: the telcos will respond with patent litigation, and with "think of the children and *AA" legislative proposals to tie the new open networks up in monitoring, filtering, and other restrictions on use.

Of the players listed in the summary, one has a history of impeding development in the marketplace to increase dependence on their own products.
This process will be open you say? So was MS XML standard ratification process.
905 of my income comes from working with MS products, but I don't want them anywhere near processes like this. Just my .02.
This could provide critically needed rural access to broadband. It would also create competition for local DSL and Cable Model monopolies. There is no downside here for consumers.
Since it's public domain then they shouldn't have any problem appointing me to their board, right?
Any word on how your data will get back to the place you are visiting? Are these frequencies suitable for low-power transmission by consumers? Should be expect yet another cellular radio network? Is that a good thing, given that health concerns have not been laid to rest completely?
I wonder if their documentation will be written in whitespace.
This is my sig. There are many like it but this one is mine.
Considering all the players, and the government would be involved, and that it is in MS's best interest to keep it open. I'm not really that worried. They want to software that can be used on any device. If they had sole control, the they would have a hard time getting other players.
Yes, I do know MS's history, and if it was just them I would be concerned..of course I would be concerned is it was under control of ANY single company.
905 is supposed to be 90%, right? I had to stare at it for a moment before I got it.

That you actually put effort into copying and pasting this product of an unhappy childish mind suggests that you should look for professional help and/or consider medication.
Some points of accuracy for your text. First, the attempt to dismiss African culture with insults does not work. There are many good ways to criticize Africa, but they do not rely on contempt for the amount of melanin in the skin. You need to find better metrics. There is, despite the attempts of thousands of people who share your medical condition, no correlation between skin color and level of "humanism".
Second, you attempt to associate free and open source software with "stealing". This is a self-defeating insult since it's so obviously the opposite of the truth. As sarcasm, it does not work. I'd suggest calling it "amateuristic", or "naive", or even "chaotic". But "stealing" does simply not hurt.
To help you, it's as if someone gave you a large chocolate cookie, and you threw it away, saying it was excrement. Basically, no-one would mind, and you would look like a fool, which you are.
Finally, you appear to evoke the Creationism vs. Evolution fights by referring copiously to monkeys. Again, if you want to insult humans, do so by pointing to aspects that are truly offensive, such as their ability to waste the bounty of cheap modern-day communications with drivel like your post. Referring to our evolutionary heritage - while perhaps the most accurate part of your text - is simply not hurtful. It's like pointing to a car and saying, in a sneering voice, "look, a mechanical horse!"
My advice would be to see, in order, a physician, a pharmacist, and an English teacher.
Thank you

I don't like the sound of that.
Why not? All the companies listed have a vested interest in getting rid of the middle-man (telcos) in order to ensure maximum profit for their respective businesses. Google wants to make sure you can see their ads on any device anywhere. Motorola wants to make a lot of those devices. Microsoft wants to do both. The telcos have done nothing but limit all of these companies (and thus, us, the consumer) with their strangle-hold on the spectrum thus far.
Any time Microsoft and Google decide to partner on something, you know the rest of us are just going to get screwed.
Because why, exactly? And before you start, try going with a reasoned argument, rather than paranoid ramblings. I know that's asking a lot, but...
Your excellent critique almost makes it seem like a good idea to respond to trolls. Nice work!
Any time Microsoft and Google decide to partner on something, you know the rest of us are just going to get screwed.
Right now, with many of us having only one choice for the local loop (or is it only called the last mile these days? I'm showing my age), we're already screwed. This initiative is the very competition you seek.

From the article:
we'll advocate for data formats and protocols that are open and non-proprietary
At least in this case, the more big players teaming up, the better. Like it or not, these companies' products are main stream and having open, non-proprietary, and UNIFORM standards defining one or all future releases of these products is a very good thing.
Are they talking white space or are they talking 700 MHz?
White space means unused TV channels, which means 470-700 MHz after the transition.
What it sounds like, however, is that they're referring to the rules that will govern the new 700 MHz allocations that were auctioned last year.
There is no "abandoned" analog bandwidth. The top 100 MHz of the UHF TV band were reallocated to other services and the TV broadcasters were "packed in" closer together thanks to ATSC's less stringent adjacent channel spacing requirements.
As both a sound engineer at a theater and an amateur radio operator, I fear that these devices will not be made to the standards required for such...versatile transmitters and that they will not properly 'check' for signal presence. It's not too much of a problem for ham stuff (stay out of my 440MHz, I'm happy)--but UHF wireless microphones in theaters utilize unused UHF television channels. I don't want to come in one day, turn on all of my Shure receivers, and have to rechannelize all of my microphones which I already set carefully. I don't know if my wariness is justified, however.
a small chunk of UHF spectrum given to the citizens of the USA to be unlicensed like 27 mhz CB radio, allowing 4 or 5 watts and any external antenna you wish to buy or build, with the sun cycle starting up again 27 mhz CB radio is going to be a complete mess for the next 5 to 7 years making local communication on 27 mhz CB radio almost impossible, since uhf does not get the DX/skip propagation conditions like HF (including 27 mhz CB radio) it would benefit many citizens and especially truck drivers that only want to talk locally to people within a few miles of their vicinity.
and do not say 'get those FRS radios they sell at walmart' because those are worthless little pieces of junk without any decent wattage on TX (1/4 watt) and the speaker audio is not good for a noisy environment like the inside of a tractor or an 18 wheeler, many truckers and farmers would benefit from a decent UHF CB radio...
i would be willing to spend a couple of hundred dollars on a good quality UHF CB radio, and i am not interested in getting an amateur radio (ham) license...
Politics is Treachery, Religion is Brainwashing
I don't know, the last time a chunk of spectrum was posted with "here there be dragons!" and otherwise left alone, we got Bluetooth and wireless networking.
Sure, there are some basic rules which keep the different devices from trampling each other, and there are licenses within that spectrum which are allowed to dominate anyone else and may not be interfered with. So, imagine what such a useful chunk of spectrum, without any licenses encumbering it, and left as a playground for anyone to use could result in.
On the whole, I'd love to see the vacated spectrum kept as a public resource with anyone allowed to put anything into it which they wish. The understanding would simply be that others will operate in that space as well so any device needs to be fault tolerant, and ideally, play nice with others.
Of course, the Federal Censorship Commission (FCC) being what it is, I imagine that we'd quickly see rules slapped onto it about "indecent" content.
Necessity is the mother of invention.
Laziness is the father.
Because why, exactly? And before you start, try going with a reasoned argument, rather than paranoid ramblings. I know that's asking a lot, but...
I would be reluctant to classify as a paranoid ramblings a general distrust of concentrated power. A distrust of concentrated power is one of the few consensus's behind most mainstream Americans. We distrust the government, so we divide it between cities, counties states and the federal, and in each of those cases, we further divide that same government into legislative, executive and judiciary branches, and often we then divide the legislative branch even further. We distrust concentrated private power, so we enact laws and have in the past broken up corporations whose power was deemed too large. We arm our citizenry to check the government further, and we even further empower ourselves and our institutions to make free speech, hold private funds, and organize politically. So... you say, given that two of the most important software companies in the world are collaborating, how could it be a paranoid rambling to distrust them? I would say, how it could be consistent with any aspect of western culture TO trust them!
This is my sig.
If they are not licensed, then by what right do you expect them to not get interference? One unlicensed user has just as much right to the spectrum as another. If the mike's were digital, they could, I think, happily co-exist with other digital users of that white-space spectrum. Outside of ham-bands, I begin to think that analog radio devices will quickly become a think of the past - the problem with analog stuff is that basically only one user (or one group of users) can use a certain frequency at a time. With packetized digital communications (and/or spread-spectrum techniques), multiple groups of users can share bandwidth at the same time.
Shared use, seems like a much more equitable use of limited spectrum resources, than the old analog 'dedicated channel' model. Still, if you are someone with analog A/V equipment, I suppose it would kind of stink. I suppose an equitable compromise might be to start by making sales of such 'legacy' equipment illegal, but continue to allow it's use for some number of years, to allow people and companies who've invested in such equipment to 'get their monies' worth' out of it, with a plan to make the continued use of such equipment illegal after a cutoff date in like 5 or 10 years.
Uhh...the way I read it is that they are coming together to formulate a plan to utilize the whitespace for communications. I think it is more that they are determining how to structure the network so that devices can interoperate with one another or like settling on a standard. I'm not sure that they are necessarily 'partnering' to form some MSoogle cabal or something....they still pretty much hate each other and want to kill one another. They just need to agree on where and how to fight in the new arena.
oops, accidentally rated overrated instead of funny
Consider how well 700 MHz propogates.
Now consider that every previous attempt to create a wireless mesh network has failed because none has ever achieved sufficient density to qualify as a mesh. Whitespace base stations (non-portable devices) can transmit at 1 watt, with a maximum EIRP of 4 watts. With a sufficiently clever encoding scheme, such devices should be able to hear each other over a long enough distance to finally get over the hump and establish a usable mesh. Portable devices can transmit at 100 milliwatts. If G-phone 2 (3?) comes equipped to use such a network... Maybe with a base station bundled in the box for $30 more...?
Has the wireless mesh concept finally come of age? I'm going to permit myself a teeny bit of hope.
Okay...you're looking WAY too deep into this. They are trying to form a standard to avoid another VHS/Betamax, HD DVD/Blu-ray format war. Once they have a standard, they can then **COMPETE** with one another while maintaining interoperability between all devices within the standard which allows consumers to make their purchasing decisions based solely on the quality of each of the competitors' products.
So... you say, given that two of the most important software companies in the world are collaborating, how could it be a paranoid rambling to distrust them?
Oh, I don't know... because the most important software companies in the world collaborating gave us *UNIX* (or, I suppose I should say POSIX), among other things.
Trust me, you're paranoid. Companies working together to agree to an interoperable standard is a *good* thing, not a "[concentration] of power".

Move to a city. The 2.4GHz spectrum is crowded.
Wi-Fi works because of its very limited range. Try it with a range of several miles.

...but if your wireless mics really are in the TV bands, and really aren't Part 15 devices, then they're Part 74, Subpart H devices, which do require a license. There are no other options. You're one of many who've been sold a bill of goods by unscrupulous manufacturers of these microphones which, by law, can only be licensed to television stations, broadcast networks, cable television systems, motion picture producers, television program producers, and Multipoint Multichannel Distribution System (MMDS) licensees (Title 47 USC, 74.832). See this for a pretty good, if slightly dated, FAQ on what's required to license a wireless microphone in the US.
These microphones typically will be offered no protection against interference from whitespace protocols like the IEEE 802.22 standard. Note that the IEEE 802.22 group is also in the final stages of standardizing a beacon protocol, IEEE 802.22.1 [pdf]. This beacon is to be present whenever the (licensed) wireless microphone is in operation, and produces a signal easier to detect (at a greater range) than the microphone itself, so that cognitive white space secondary users can more reliably determine that that television channel is occupied and move elsewhere. This system avoids interference to the wireless microphone by the secondary user.
The IEEE 802 Working Group for TV white space is the 802.22 group. Early on in the work of this group it was recognized that it was important to detect the presence of wireless microphones, for just the reasons you describe. Their solution was the development of a beacon protocol, to be transmitted in the same TV channel as that used by the microphone. (The microphone uses much less than the full TV channel bandwidth, so there is room to do this.) The beacon is carefully crafted to be quickly detectable by the secondary user at long range, even in the presence of severe multipath distortion, and is intended to be placed at the wireless microphone receiver. In this way, scanning secondary users are much more likely to detect that the channel is occupied, and move elsewhere.
With luck, Google & Co. will adapt this or a similar scheme.

Trust me, you're paranoid.
Somehow, I don't see that attempt working.
LOL, nicely done, AC.
First off, ATSC channels are the same 6MHz as NTSC channels.
Secondly, if you take a peek at a spectrum analyzer, you'll see a big, fat, non-peaky pedestal of signal for digital TV. It's about as immune to low-level interference as I am to ebola.
Thirdly, radio astromony is given a "big" empty space (channel 37).
Fourthly, the day that we call 100mW "low-level interference" is the day that we all, women included, have seven testicles.
Fifthly, these devices are so overpowered that they knock out cable TV.
Sixthly, there are ways (other frequencies, spread spectrum, burst transmission) to control high-bandwidth wireless devices wirelessly.
Seventhly, I had to go up to "sixthly." If you're really in the broadcast and communication "world" (do you mean industry?), you should consider boning up or getting out.

Ideas for the troll response generator?
I've always found this topic curious. As much as open source, no software patents or an anti-RIAA stance, I would have expected something like this to be avidly supported by the vast majority of us.
In this latest story, it would seem like the tide is gradually turning as people begin to realise the enormous potential benefits something like this can bring.
Google sums up the change on their web site Free the Airwaves. From what I gather, devices will only be able to be sold as long as they keep to a restricted set of wavelengths, so there shouldn't be any worry about interference.
In theory, it should allow cheaper wifi, broadband, free mobile phone calls (as they would communicate directly with each other, at least over smaller distances, and much further afield too if smaller entrepreneurial setups start to link together), and healthy competition in the overall communication sector.
We've had extortionate prices for mobile calls/texts for WAY too long. It's time to put an end to the nonsense.
Why OpalCalc is the best Windows calc
I really hope part of the spec is a sort of universal RTS signal, so even if several different networks in proximity used the same band, they would be able to play nicely. Of course, in crowded areas this would result in potentially much lower throughput, but at least it wouldn't totally hose any of the systems (and on a shared public medium, that's as much as you can ask for anyway, right?).

"However, several features that are contemplated as possible options to minimize the interference potential of WSDs, such as dynamic power control and adjustment of power levels based on signal levels in adjacent bands, are not implemented in the prototype devices that were provided."
