There is nothing wrong with anyone's equipment. Light Squared wants to use spectrum that impinges on high accuracy GPS systems. These systems are integral to air safety as well as our military (all of which had systems that were designed to the standards that Light Squared now wants to infringe on).

As a more technical explanation, because of the spread spectrum nature of the signals, the "skirts" now can intersect if Light Squared does not provide a sharp enough filter on their transmission. Their "solution" is to force a front end filter on the high precision GPS receivers rather than controlling their own power spectrum AND expect the existing device owners / manufacturers to foot the bill.

Then lightsquared should sue them for unlicensed use of their spectrum

They didn't pay for it. SkyTerra got it for free and LightSquared bought them out. What LightSquared really wants, according to industry analysts, is a frequency swap for more valuable spectrum WITHOUT having to pay for it. They are basically holding GPS hostage in the hopes the government will pay them off with frequencies that could otherwise be auctioned off.

Given the FCC's bungling of this whole Charlie Foxtrot, that's exactly what needs to happen. Swap spectrum, eliminate/mitigate the interference issues, and most everyone is happy.

No way.
Lightsquare originally intended to offer only satellite broadband. They took a gamble to try and convert satellite only spectrum for ground based use and lost.

Lightsquared needs to buy ground based spectrum like everyone else instead of trying to screw americans out of our GPS network that we have been paying for and building since the 70s.

Re: all I hear is...

I'd agree with you except that the FCC waived LightSquared's use of the spectrum for terrestrial use. LightSquared's poor engineering efforts and the FCC's negligent oversight brought this issue about.

Yes, that is the oft-quoted public storyline. I find it disgusting that the follow up to that pair of stinky errors is the insistence that they be allowed to go through with it. They messed up, and need to retract. Can't businessmen and politicians find a way to make mends without continuing the garbage? That's why some of us are allowing the "spectrum swap" idea as a (unfair to legitimate users like other cell companies that bought at auction) solution, since it at least solves the main issue (GPS interference). After that, the damn phone companies can rowl in the mud for all I care to even that score, as long as they don't mess up GPS while they're duking it out.

I am COMPLETELY fine with that. For once in my life I agree with openbox. How many subsidies have AT&T and Verizon benefited from? Let's subsidize a competitor for once.

Oddly enough, although I find this absolutely abhorrent (holding GPS hostage until a spectrum swap that fixes this issue), I find it absolutely abhorrent on a level many orders of magnitude lower than I find it absolutely abhorrent that Lightsquared would be allowed to impinge on GPS spectrum as they are insisting they have a right to do (which is bogus). It is a far better compromise among thieves and regarding the citizens for Lightsquared to get a spectrum swap away from the GPS-interfering frequencies than it is for them to simply obliterate GPS. I'm hoping this spectrum swap idea is the relief valve of the high-pressure crap they are doing.

LightSquared wants to use those frequencies -originally intended for use from space (ie. low power when actually received on Earth) - in a way that they were NEVER intended to be used (ie. high power terrestrial transmissions) which will overpower the receivers on ground-based GPS systems.

If these frequencies are used as originally intended there would be NO interference with ground-based GPS as the GPS receivers are able to filter out the low-power 'noise' in those frequency bands.

What LightSquared is proposing is like a 5 milliwatt baby crib monitoring radio with a 50' range suddenly boosting it's output to 100KW and clobbering all receivers within a 100 mile radius.

Do you ever wonder why AM or FM radio stations are separated by the amounts they are on the radio dial? It's because of interference. Ditto with GPS frequencies and those that LightSquared got their hands on. It's the FCC that screwed up here by letting the GPS guard bands get overrun by LightSquared's shift to high power terrestrial use. Had LightSquared stuck to space-based use of these frequencies, we would not be having this conversation

I'm quite sure that they do.

I also have met a lot of thieves in my life that want to use the stolen goods that they paid other thieves for. You are suggesting that we allow them to do so.

I'm really lost how you can call them thieves? they paid for the rights to the spectrum. They have every right to use it.

Their "solution" is to force a front end filter on the high precision GPS receivers rather than controlling their own power spectrum AND expect the existing device owners / manufacturers to foot the bill.

Their solution is a reasonable one; i.e., ask the GPS industry to design their receivers to only be sensitive to signals allocated to the GPS band, and filter out signals outside that band. It's feasible, just not as cheap as whining about having to deploy proper equipment instead, or purchasing the spectrum from Lightsquared.

Re: all I hear is...

Red shifted satellite GPS signals move 25 mhz into the satellite only spectrum lightsquared wants to use.
The reason the spectrum is satellite only is it is a buffer for GPS and other weak satellite signals will not jam GPS.
Using that spectrum as satellite only is already the compromise with GPS.
Trying to use it for powerful ground transmitters will jam the red shifted GPS signals.

Also GPS is owned by the US tax payers we have been paying for it since the 70s. The GPS industry makes devices for us to use the GPS that we all own.
The GPS industry purposely designed their equipment to listen to the spectrum lightsquared wants to use to pick up the red shifted GPS signals.

I was under the impression our government could do anything when it comes to national security. Like tell Light Square to go hang themselves. Because Interfering with Air Safety and Military Traffic would be bad for national security.

LS probably wants a spectrum swap.
