LightSquared has outlined a comprehensive solution to the problem of interference with GPS receivers. This solution will permit LightSquared to proceed with its business plan, protect the public’s stake in GPS and lay the foundation for the future co-existence of a variety of wireless broadband services and GPS.
Early test results indicated that one of LightSquared’s 10MHz blocks of frequencies poses interference to many GPS receivers. This block happens to be the specific set of frequencies that LightSquared planned to use for the initial launch of its nationwide wireless broadband network.
Based on those same early test results, LightSquared determined that another 10MHz block of the spectrum did not create such an interference risk. This block is lower on the spectrum band and located further away from the GPS frequencies, greatly reducing the risk for interference.
Test results show this lower block of frequencies is largely free of interference issues with the exception of a limited number of high precision GPS receivers that are specifically designed to rely on LightSquared’s spectrum. In its original plan, LightSquared planned to move into this other frequency block as its business grew over the next two to three years.
After assessing this information, LightSquared immediately began developing an alternative deployment plan focused on the lower block of spectrum to launch its nationwide wireless broadband service. It also entered negotiations with Inmarsat, the satellite company that controls the alternative block of spectrum in the L Band, to accelerate the schedule for LightSquared to begin using the frequencies.
LightSquared believes that its next-generation, 4G LTE wholesale network can live harmoniously, side-by-side, with GPS users. Enlightened and responsible spectrum management will give the American public the best of both worlds – a world class wireless broadband network and a GPS service that continues to enrich and protect our lives. With this plan, LightSquared has taken a giant step toward that goal.
