The committee chairman questioned if this issue could have been prevented and argued that this matter raises important implications for spectrum policy going forward.

The two witnesses, both from the FCC, said that the commission has acted responsibly since learning of the GPS community's concerns about harmful interference from the LightSquared terrestrial network. They said the FCC initially issued a conditional waiver in order to prevent LightSquared from deploying commercial service in the L-band until it resolved these concerns.

The FCC witnesses also mentioned that they are reviewing possible alternatives in hopes to find a solution that addresses the interference concerns while allowing broadband use of the spectrum next to GPS.
