quote: LightSquared has proposed that it operate at a reduced power than the levels used during the testing. With low power usage, LightSquared believes its services would only affect 10 percent of devices.
quote: LightSquared has come out with its most concrete claims so far that its LTE network will not interfere with GPS services across the US. The start-up says an Alcatel-Lucent laboratory has carried out extensive tests on devices from three GPS vendors, whose preliminary results demonstrate that those devices are not disrupted by the LTE signals in nearby mobile satellite spectrum.
quote: LightSquared has proposed various remedies to the GPS issue, including restricting its services to the area of its spectrum which is furthest from the navigation service bands.
quote: These tests are meaningless unless they were conducted with GPS receivers that meet their (well known but ignored) filtering requirements.
quote: What you're missing is that if the GPS folks had played by the rules and used proper filtering in the first place, this wouldn't be an issue. But when GPS began there was no LightSquared, so they cheaped out on the filters since there was nothing there to filter.
quote: The units which fared well in the test are probably bigger units with better antennas and more power for electronic filtering and signal processing. If LightSquared's project goes live, you can probably kiss the GPS in your phone goodbye.
quote: Imagine coming up to an intersection, waiting to have your gps tell you which turn to take, and all of a sudden it loses the GPS signal. You have no idea which way to turn.
quote: I wouldn't trust anything they said. They just want to make money and don't care who they interfere with in the process.
quote: I can apply that to the GPS people who are effectively squatting on LightSquared's spectrum. They just want to steal this spectrum (because stealing the spectrum is cheaper than replacing all those GPS units with ones that work properly) and don't care who they steal it from in the process.
