GARMIN SAYS 4G SYSTEM A THREAT TO GPS
Garmin is standing by its position that a proposal to build a network of 40,000 broadband transmission towers around the U.S. could severely disrupt GPS service. As we reported last week, LightSquared has received conditional FCC approval to install the massive system to carry 4G signals, the conditions being that it restrict its signals to their assigned frequencies on the L Band 1 (1525 MHz—1559 MHz) and test existing GPS devices to see what kind of interference the transmitters might cause. GPS uses the a frequency range of 1159-1610 MHz, which is right next to the LightSquared signal. Garmin's Jessica Myers told AVweb in a podcast interview that Garmin has done testing on its own and determined there's no practical way for the two systems to coexist.
