Most of the witnesses and some lawmakers on the committee called for additional testing of LightSquared's proposal to use only the lower band of spectrum for now, which it submitted on June 30. LightSquared Executive Vice President Jeffrey Carlisle said about 130 products were tested in that band during a series of tests earlier this year.
However, LightSquared has now submitted an additional plan to the FCC to try to find a solution to the interference, Carlisle said. In the paper filed Wednesday, the company proposed committing itself to a certain level of broadcast power from its LTE towers, measured on the ground at various distances from each tower.
The company also proposed providing a stable satellite signal for GPS augmentation services, which high-precision GPS units use, at a different part of LightSquared's band.
If nothing else the pressure to compromise to move this along seems to be growing.
