The super-powerful mobile terrestrial broadband developed by United States company LightSquared has been banned from commercial use because of its interference with industry standard GPS systems. Last week the National Telecommunications and Information Administration (NTIA) concluded that Light-Squared's proposed network "will impact GPS services and that there is no practical way to mitigate the potential interference at this time." In an eight-page letter to the chairman of the Federal Communications Commission (FCC), the NTIA's administrator, Lawrence Strickling, said its findings were based on testing and analyses, together with "numerous discussions" with LightSquared. "It is clear that LightSquared's proposed implementation plans... would impact both general/ personal navigation and aviation GPS receivers."
