LightSquared Proposes to Operate at Lower Power

In an effort to mollify concerns about signal interference with GPS systems and users, LightSquared now has proposed operating at lower power for a period of time. To the extent that transmitter power is what causes the interference, the lower mobile tower transmission power levels should help. Just how much help that move will have, has to be tested.

Also, LightSquared only proposes to operate at lower power for a period of time, then would ramp power levels back up. Some might consider that an odd proposal. Perhaps the thinking is that GPS receiver manufacturers and end users would then have a transition period to wean themselves off devices that currently experience interference.  LightSquared proposes lower-power solution

Some might doubt this will help LightSquared. In principle, the new user has to demonstrate it does not interfere with other existing users. If interference again becomes a problem in the future, LightSquared could be barred from operating. Permanently lower power levels would seem to be a  different matter.
