FCC to LightSquared: Keep Testing

Article Comments

Sep 14, 2011, 7:25 AM by Eric M. Zeman

The Federal Communications Commission has instructed LightSquared to perform more tests of its planned Long Term Evolution 4G mobile broadband network in order to ensure than it doesn't interfere with GPS signals. The FCC thanked LightSquared for its revised proposals, but noted, "The results thus far from the testing using the lower 10 MHz showed significant improvement compared to tests of the upper 10 MHz, although there continue to be interference concerns with certain types of high precision GPS receivers, including devices used in national security and aviation applications. Additional tests are therefore necessary." LightSquared's proposed network uses L-Band spectrum, which is adjacent to the spectrum used by GPS satellites. LightSquared hopes to blanket much of the U.S. with an LTE 4G mobile broadband network. It has already signed more than a dozen wholesale partners that hope to use the LTE network to sell their own mobile broadband services.
