GPS industry is to blame for interference with LTE signal says LightSquared
One day before a deadline to file a report with the FCC, LightSquared handed over its findings to the Feds. In its report, LightSquared said the blame for the interference to GPS signals that comes from its LTE service belongs to the GPS manufacturers. In the report, the GPS companies are blamed for using spectrum over the last eight years that has already been awarded to other users. The report goes on to say that the GPS manufacturers are not interested in compromising or finding a solution and instead are demanding to the government that LightSquared be blocked from using its own spectrum to provide service.

According to LightSquared, GPS manufacturers could have prevented this problem by adding a 5 cent filter to their products. The GPS industry has complained that LightSquared's terrestrial network, using the L-Band spectrum that the FCC is allowing the latter firm to use, is at fault. This is a rather pricey economic matter that needs to be worked out as LightSquared claims that its service of providing wholesale wireless broadband will save consumers as much as $120 billion. The company has recently signed a contract with mobile carrier Sprint and has worked out deals to allow other firms like NetTalk and Best Buy to use its LTE pipelines to attract customers for discount cellular service.

As we reported, LightSquared has proposed a solution to the FCC that they claim will remove 99.5% of the problem. The company proposes using a lower block of spectrum and a reduction in the power output of its towers, and says that it still requires the cooperation of the GPS companies to move forward. While this might help solve one problem, like the little boy who plugs the leaky dam with one finger while a new leak starts gushing, LightSquared still needs to deal with complaints about interference from the Department of Defense and the FAA.

Finally... LightSquared fights back. The GPS industry has been going after LightSquared to hide their own short comings. They had knowledge of this possibly happening from the FCC since 2005. They just didn't care. I say that the GPS industry be made to buy LightSquared new spectrum in the newly freed up 1300-1390 MHZ freq to replace LightSquare's 1525-1559 L band.

Lots of luck if Lightsquared is going to go after the U.S. Dept of Defense and their implementation of GPS.... Do they think they are going to get the DOD to revise all of their GPS-guided weapons?

Lightsquared is stupid and so is anyone who agrees with them. GPS has been around for A LOT longer than LTE has, so how is it that GPS interferes with LTE when GPS was first? They need to Lear and get their facts straight before blaming something that came first.

Wow..your an idiot. Just because they came first doesn't mean they implemented it correctly and doesn't mean it can't be done better. And it they prove that the GPS signal is leaking into their spectrum that they bought then they should have to fix it. LightSquared bought the spectrum so they should have the right to use it. Again..this is assuming that what LightSquared is saying is true. But don't start calling them stupid and they don't know what they are talking about just because GPS was first. I also hope you realize that having other providers of LTE in the marketplace will increase competition and drive down cost. Why do you think Europe has such cheap internet, they have more competition. We should be glad LIghtSquared is coming into the marketplace.

Skymitch89 that has to be the most moronic and uninformed comment I have come across in a while. It has nothing to do with who was there first, it has to do with who is playing by the rules and who owns that spectrum and has a right to use it. Your argument would be similar to saying you own property that you have lived on for twenty years, no one had lived on the adjacent property forever so you decide to build something on it. You live there with no neighbors or no problems and your structure stands with no problems or contest from anyone. Then I come along and buy that land from the previous owner who wasn't using it, I see that you have built something on my land and ask you to remove it because I now intend on using the property I just bought. You're argument is really going to be "No, I was here first" ? My response will rightfully be "you didn't own the land then and you don't own it now you moron, get the f**k off my land!" Use some logic before you comment please.

Very nice analogy...

Actually in the above analogy if the owner of the land had never contested your use of it for a certain period of time you would own it by default in many states.

Not the point of the analogy. Go ahead and assume that the previous owner of the land just never checked because they didn't care about the land, but the new owner does, and input whichever state doesn't have squatting laws, do not affect this scenario, and support my point that Skymitch89's comment was completely ridiculous. Thanks.

that is an amazing analogy!

So... LTE is important, I get it... but aren't a lot of legacy GPS receivers present in a lot of existing products, some of them in mission critical applications? (aviation, mining equipment, MILITARY...)

The fact that GPS is at fault makes perfect sense. Why would a company buy spectrum that is unused and that unused spectrum is causing problems for something already in use. The only way that seems logical is that the GPS signals are occupying more than they are alloted. The equipment Lightsquared has access to is infinitely more precise than what was available at the advent of GPS.
