Since they used a signal generator to simulate the LightSquared
transmissions, and could therefore insure the signal stayed within the
allocated frequency band, it would appear that the fault is likely in the
GPS receivers.

However, this and other articles seem to claim the LightSquared
transmissions are "interference" - implying that they emit unacceptable
signals outside their allocated frequencies. I'm not sure it would be fair
to characterize their emissions as "interference" if in fact the GPS
receivers are "listening" too sensitively to frequencies outside their
working bands.

In the end I expect LightSquared is going to be forced to change their
operating plans because of the installed base of GPS receivers,
irrespective of the quality (or lack thereof) of the GPS receivers or
LightSquared equipment.
