LightSquared mobile broadband network still interferes with GPS signals

LightSquared mobile broadband network still interferes with GPS signals
Last week, the results from the latest testing of LightSquared's mobile broadband network were revealed by a leaked document, and they did not look very promising. In particular, the network that the LTE wholesaler is trying to deploy was still found to interfere with GPS communications despite the company's claims that it had found a solution to the issue.

Now, the test results have already been made official and confirm what the leaked papers stated. LightSquared's network is unable to affect the operation of cellphones, but can cause “harmful interference to the majority of other tested general purpose GPS receivers,” as the U.S. Defense and Transportation departments said in a joint statement on Wednesday. Besides, the LTE wholesaler's towers can interfere “with a flight safety system designed to warn pilots of approaching terrain,” as indicated by a separate test conducted by the Federal Aviation Administration. Sanjiv Ahuja, CEO of LightSquared, reiterated that the GPS is to blame for lacking the filters necessary to block out the frequencies licensed to his company. 

Back in July, LightSquared and Sprint agreed to a 15 year deal that grants the former with access to Sprint's 3G network. At the same time, Sprint will be allowed to purchase half of LightSquared's LTE network. However, if the government prevents the wholesaler from turning on its network, that might hinder Sprint's transition to LTE.

Well I suggest that Light Squared start handing out those filters for free to those companies that will have issues if they turn on their service. The LS ceo seems like he's blaming those other companies for not having the filters. News for ya Sanjiz, or whatever your name is.... everything was working fine before your company and it's YOUR responsibility to make sure that YOUR network doesn't interfere with operations already in progress. And what happens if one of those filters decides to fail as an airplane is flying over the Rockies? I rather they didn't have to use any filters. How about LS look elsewhere for their network (I mean different frequencies)?
