Cellphones were significantly affected in the original testing. With Lightsquared's current, temporary restriction to the lower portion of their spectrum proposal they claim that only high precision GPS receivers (e.g. survey or ag) will be affected but there's been very little testing of that claim.
Pretty much all that "enhanced GPS" offers is a more rapid initial position solution along with a pre-GPS lock location based on cell tower signals that's pretty inaccurate.
Not true by a long shot when you count all the actively used GPS receivers. Heck, just the installed cost for every aircraft GPS has to be in the billions. Then there's all the military hardware using GPS. AFaIK they've got medium caliber munitions that have GPS receivers in them.
That's not a viable solution in many cases. First you've got plenty of GPS receivers with integrated antennas, most of which have no extra room for any additional filtering even if it were possible to insert a filter. Second most remote GPS antennas are amplified and that generally means that at least some of the additional filtering has to be added to the path between the antenna and it's internal amplifier. Otherwise that amp will become overloaded by the LS signal and the GPS signal won't make it through.
Sorry but all the above it pretty much impossible with current technology including what LS is proposing.
"Their technology" is the wireless telecom standard of LTE. This is the same system that AT&T and T-Mobile have started to deploy in the US. It contains a ton of Ericsson IPR as well as inputs from all of the major companies. LTE is a global standard and is being deployed globally too. There is nothing special about Lightsquared's technology. The difference between them and the teleco is the spectrum that is being used.
The military has that issue covered with missiles that home in on jamming signals. Perhaps we can get the army to try them out on the LS transmitters should they go active.
In Corporate jobs, that'd have to be pared down to eight three-word bullet points so we could all enjoy some Death by PowerPoint style briefings for management. Writing isn't read by anyone anymore.
- Use bullet points.
- Be brief.
- Mold consensus toward management dictates.
And those of us who are sitting in the room this week to look over LS results are doing it with Macs, PCs, powerpoint and on rare occasions MatLab. We don't have fun toys, but we have expense accounts the necessary liquid refreshments needed to get the work done!

I can tell you, since this meeting is a matter of public record, that there was little discussion on this issue. A paper was presented and most people just kept checking email. But the good thing was that no action was taken. From a standard's perspective the issue is advisory while we wait for the FCC ruling. No one in the room is willing right now to make a public, on the record comment.
Not yet. Perhaps after the local server is synch tonight.
No. It is a new proposal from LS.
"Sure, buddy, you can use our Gambino 2000 to make your pretty pitchers. But it'll cost ya!!"
