LightSquared Wants To Share Weather-Balloon Frequencies for LTE 141
IDG News Service reports (as carried by PC World) that LightSquared, having lost some of the spectrum they'd hoped to use for a nationwide LTE network because of worries it would interfere with GPS service, has a new plan: to use some of the spectrum currently reserved by the federal government for uses like weather-balloon communications. From the article: "The new plan would give the carrier 30MHz of frequencies on which to operate the LTE network. That's 10MHz less than it had wanted but still comparable to the amount of spectrum Verizon Wireless and AT&T are using for their LTE systems, which in most areas use just 20MHz. Wireless network speeds are determined partly by how much spectrum the network uses, so LightSquared might be able to deliver a competitive service for its planned coverage area of 260 million U.S. residents."

And also, Why would Weather-Balloons need that much frequency juice in the first place ?
Its older, cheaper, disposable tech. Might only be 400 baud downlink but usually a pretty wide signal. Simple FM/FSK modulation maybe. The problem is you launch 10 to different altitudes, due to frequency drift from being cold (cheap, remember?) you might find that a struggle to make them all fit without interfering with each other. On a boring fall day you don't launch 10 at a time, but for all I know in a hurricane (literally) you might drop 10 at a time.
Congress already told NOAA to stop using the bottom half or so of the band. The problem is radio allocations are done by the ITU... This is the usual american arrogance problem where it turns out the FCC only regulates inside the US. If someone in Canada wants to launch at 1770 MHz, which is well within ITU regulations, short of bombing the Canadian weather station I'm not sure what they intend to do about it. Just accept the interference I guess.
Also the 1700 MHz band has coprimary with radiosondes and met satellites. The weather satellite people are going to be pissed if their frequencies are reallocated only over the USA.

It'll be a long while before something will "lessen the importance of weather balloons". Unless you can figure out a way to measure air pressure, humidity, temperature, and wind direction from 0-70k ft regularly without launching balloons or dropsondes, they'll be needed. And if you can figure out a way to do it, the folks who fly the Hurricane Hunter aircraft would like a word with you so they can stop flying in and around tropical cyclones.

Still, Lightsquared should be denied - they acquired satellite frequencies cheaply, because of the known limitations. They then wanted to repurpose them for terrestrial use, vastly increasing their value. But, it was proven that couldn't work without interfering with other satellite usage (GPS). The government doesn't owe them anything - they can still use those frequencies for satellites, which is exactly what they paid for. Because they couldn't get much more value than they paid for, they're now asking for a "freebie." They have an exaggerated sense of entitlement. Screw them.

The GPS industry didn't screw them over. It was there first, and it is far more important to EVERYBODY than yet another carrier building a network on the cheap.
That being said, if weather baloons is all there is in this proposed frequency range, I say let them have it, as long as they provide unlimited sim cards to weather baloon services and let them swap in cheap cellular radios for what ever they are using now.
Somehow, I suspect they have glossed over what other services might be in those frequency ranges.

Least they are not going down without a fight after the GPS industry screwed them over. They PAID spectrum to start a business on but interference with GPS devices WHICH clearly is the fault of companies that made the GPS devices screwed them bad.
They paid for spectrum that was specified for satellite to ground communication. They obtained a waiver to use that spectrum for ground-ground on the condition that they not interfere with adjacent satellite to ground users. They failed to do that, and so their conditional waiver doesn't hold. They are still free to use the spectrum they bought on the terms under which they bought it, they just don't have any business model there because their entire business model hinged on the gamble that they failed to pull off.
At this point, they seem to have moved to plan B 'Act injured and demand that the feds give them a handout because they deserve to succeed'.

You don't realise how cheap the sondes are. There are hundreds launched every day, and they don't get them back. They have to be incredibly cheap and there are no GSM technologies cheaper than a simple FM radio.
There are technical limitations too - GSM only works up to about 5km, above that they will likely fail. Sondes usually fly to about 30km.

The filter isn't all that difficult, regardless of power level.
Uh, you do realize that the GPS signal is already below the thermal noise threshold, right? Furthermore, you do realize that, due to pesky physics, any filter reduces the passthrough signal? No doubt you also realize that, due to pesky physics, the billion-times-stronger-signal LS ground stations would have harmonics dissipating energy in the GPS bands?
The filter isn't all that difficult, regardless of power level. The GPS receivers are deliberately trying to receive out-of-band spectrum that was not licensed to them to compensate for their cheapness. Even Garmin and Trimble knew there were problems with their equipment and had been cautioning investors about the problem since 2001 (before LightSquared).
Damn straight. It was a conspiracy to put LS out of business; a conspiracy so vast and intricate that it started a decade before the innocent, virtuous underdog LS demanded the modification of the terms under which they purchased their spectrum license. Besides, everyone knows that you get a better quality of signal if your receiver deliberately receives on other bands. Occam would be proud of your incisive analysis of the situation.
Or, perhaps GPS manufacturers didn't put tighter bandpass filters on their receivers because those filters would further attenuate the GPS signal that is already below the noise floor. Just a thought. Nevermind, the conspiracy makes more sense.
If the FCC had been more awake, it might have stopped this after $50M down the drain instead of $4B. That's what Congress wants to know [and I do, too].
If only a nanny government would have protected them from their stupidity and lack of undergraduate RF communication theory, they would have saved money!
No, this was the correct outcome: the FCC raised an eyebrow when LS claimed they could make this work (I mean, this doesn't require a PhD in RF to understand there's probably no way this would end in success), but allowed LS to try anyway after they insisted they wanted to do so. Predictably, LS failed to achieve the standard.
I suppose you would prefer a government that prevents possible failure by restricting everything to known, proven approaches, but I don't. The freedom to fail is fundamental.
It seems fair to give LightSquared some alternate spectrum that they can use to compensate them for the $2B lost on the spectrum that they already paid for.
No, that would not be fair. LightSquared thought they could pull a fast one on the laws of physics by acquiring spectrum with the deliberate, ulterior intent to repurpose it for terrestrial broadcast. There's a reason they obtained the spectrum so cheaply: it can't be used by billion-times-stronger-than-GPS terrestrial broadcast stations without interfering. Had they chosen more appropriate spectrum then this issue would be moot. None of the major carriers attempted to do what LS did because the major carriers aren't retarded like LS is.
If a house flipper were to buy an already-condemned house for $50 and then the government fails to rescind the condemnation after they haphazardly attempt to shore up the roof with $10 worth of rotten 2x4's, perhaps you believe the poor house flipper has been wronged. Perhaps, in your mind, they should seek redress from the government for not protecting them from my own stupidity and therefore they should be entitled to receive a different, uncondemned house for free from the government.
BTW, LS already laid off their technical staff. At this point it's likely that all they have left are execs and a legal department whose job it is to rent-seek. They are going to be this decade's SCO.
This is just a symptom of the Steve Jobs disease.. (Score:2, Informative)
Unfortunately, most average citizens have no understanding of wireless technology, so when a guy like Steve Jobs came along and offered them a consumer gadget that requires loads of bandwidth they buy it by the millions. Now they, and the politicians they elect, and vendors who seek some of their money are locked in a battle for unlimited quantities of something that is limited... bandwidth within the RF spectrum.
The hard truth is that there is a limit to the available spectrum, and that limited resource should only be allocated to uses that can only be performed wireless. It borders on the criminal to have smartphone companies building video and web browsing into phones... individuals filling their vacant cranial cavities with individual streams of Youtube cat videos, Justin Bieber music, and other individualized streams of pablum should not be competing for use of the nation's RF spectrum with satellite communications, GPS signals, firefighters, police, air traffic controllers, national security, TV and Radio broadcasters (who each serve millions with their broadcast pablum) and so on. Broadcast signals (like GPS, radio, and TV) should have priority since they each serve an unlimited number of people with their bit of the spectrum. Signals that only serve a single civilian user should be the absolute lowest-priority in the system.
Want to make a phone call from your home to your office? Use a land line.
Want to make a call from your car? Cell phone is fine... it's the only way to solve the problem
Want your laptop to talk to a printer? Plug in a cable (network, USB, etc)
Want a security camera? Run a wire
Want you pilot to talk to the control tower? That requires wireless
Want to know where you are while hiking, boating, flying or driving? GPS is great, it uses little bandwidth and serves millions of people, and cannot be done with wires.
With hard-wired networks, there is no limit to the bandwidth... you can just pull more cables when and where needed and your use of bandwidth has no impact upon your neighbor's use of bandwidth (he can pull all the cables he wants on his property). With wireless, on the other hand, each user is consuming a slice of a national asset which he/she does not individually own. There is no way to increase the available RF spectrum... if you want more for something then something else must get by with less. Additionally, most people do not understand that some frequencies of RF energy work better for short-range communication and others for long-range... and some frequencies can be used with small-and-cheap electronics while other frequencies require bigger and more expensive circuits (although this latter limit changes over time of course as technology advances).
Unfortunately, as long as carnival barkers like Steve Jobs keep offering consumers new shiny baubles that need more bandwidth, there will be other jerks like Lightsquared who will try to make a buck by promising consumers more of the RF spectrum (and gambling that public pressure from the uninformed masses for more will force the government to allocate more) for stupid shiny objects at the expense of vital things like navigation, public safety, national security, etc.
