In a letter to Defense Deputy Secretary William Lynn and Transportation Deputy Secretary John Porcari, Lawrence Strickling, the head of National Telecommunications and Information Administration, said the agencies should work with LightSquared to test whether its network still interferes with GPS devices on the lower 10 MHz.

Although LightSquared claims moving to the lower 10 MHz will resolve the interference problems with most GPS devices, the company acknowledges there are still problems with some high-precision GPS devices. LightSquared has said it will help develop filters to mitigate the problems with high-precision devices. Strickling told the federal agencies to concentrate on testing cellular and personal navigation receivers. The agencies will test the high-precision devices once LightSquared presents a plan to fix those interference issues. "That data, combined with information the Federal Communications Commission is collecting on receiver design and specifications, will allow us to understand more completely the interference interaction and causation and provide necessary information to determine whether we need to propose any additional operating condition on LightSquared to mitigate overload from LightSquared base stations to these types of devices," Strickling wrote.
