LightSquared’s proposed wireless broadband network “cannot exist” with the U.S. military’s Global Positioning System technology, Air Force Space Command Commander Gen. William Shelton reiterated Sept. 20, reports Philip Ewing at DOD Buzz.
Even though LightSquared’s alternative proposal for its network would move its signal farther away from GPS, it would still squelch the harmonic frequencies that precise receivers use, Shelton said during a question-and-answer session and subsequent discussions with reporters at the Air Force Association trade show in Washington, D.C.
As for the idea of installing “filters” to protect GPS receivers, the concept is cost prohibitive, Shelton said, adding that the only viable solution is having the FCC move LightSquared’s network up or down the spectrum.
