The gloves are off in a standoff between the U.S. Global Positioning System industry and a satellite communications vendor seeking to light up a broadband satellite and terrestrial network to blanket the country.
GPS interests say plans for the satellite and terrestrial voice and data network with 40,000 base stations will operate too close to GPS on the spectrum and cause damaging interference to the entire system. They accuse the vendor of trying to slip past regulators an increasingly powerful and larger terrestrial component to its hybrid satellite and cell system.
