Re: It's a shame the government is ruining this wonderful idea
said by Chubbysumo:Parroting LightSquared's repeatedly-discredited arguments isn't going to make them any more valid then they were when LS first made them.
See above this one comment. GPS receivers have been equipped with inadequate RF filters for many years, and have been allowed to get away with it.
said by Chubbysumo:Whether you care or not is inconsequential. Spectrum allocations, all spectrum allocations, have assigned uses. That can only be changed if such changes are in the public interest and are "practical." In this case, the requested change was deemed impractical.
I dont care what their neighboring spectrum was "supposed" to be used for,
said by Chubbysumo:It's only been "shown" by LightSquared's studies. Every other study and experiment I've seen has only gone to prove what any reasonably competent radio person already knew: You cannot stick exceedingly high-powered transmitters near exceedingly-sensitive receivers on nearby frequencies and expect the latter to work well--if at all. It's physics as we know it. Filters cannot fix it, even if it was reasonable to expect millions of existing GPS owners to have their GPS' retrofitted, or throw them away and buy new ones, for the benefit of Falcone & Co.
It has been shown in studies, that if the GPS devices have proper RF filters, there was no interference.
LightSquared got some spectrum on the cheap and tried to get it re-purposed. It was an effort that any half-way-competent radio engineer could have told them was never going to fly. One can only assume they either had incompetent technical consulting or they ignored good advice. Either way: This is their own fault and, given what the way they've gone about this says to me about them, the sooner they die the better for all concerned, IMO.
