Tests show LightSquared interference with 75 percent of GPS receivers
from GPS World
U.S. government tests conducted in November showed that 75 percent of GPS receivers examined were interfered with at a distance of 100 meters from a LightSquared base station. The report states that "No additional testing is required to confirm harmful interference exists," and "Immediate use of satellite service spectrum for terrestrial service not viable because of system engineering and integration challenges."
