'Facts and Engineering' to Settle LightSquared's Fate: FCC
The Federal Communications Commission today re-stated that LightSquared will not be allowed to operate its planned Long Term Evolution network if it interferes with GPS systems. The FCC gave LightSquared provisional permission to use L-band satellite spectrum for its terrestrial LTE network — as long as it could prove the network wouldn't interfere with nearby GPS signals. "We're not going to do anything that creates problems for GPS safety and service as we explore technical solutions that will both protect GPS and allow a new service to launch," FCC Chairman Julius Genachowski said during a press conference today. A number of tests conducted by a range of private and government organizations in the last few months, however, have shown that LightSquared's network does in fact harm GPS signals. It renders GPS services useless in areas where the LTE network operates, endangering, among other things, airborne aircraft. LightSquared proposed to switch the channel it intended to use for its network to create a barrier protecting the GPS spectrum. The FCC today said that it does not approve of this "guard band" idea, as it leaves too much spectrum unused. The FCC wants to find a solution that protects the GPS systems while also allowing LightSquared to launch its network, which will pump $14 billion into the infrastructure market over the next eight years. In the end, Genachowski said that it will be the "facts and engineering" that determine the fate of LightSquared's planned LTE network.
T-Mobile Rolling Out LTE-U
T-Mobile today said it is beginning to upgrade its 4G network with LTE-U this spring. LTE-U allows LTE to operate on the unlicensed spectrum in the 5 GHz band, which is typically reserved for WiFi.
FCC Chairman Opposes Idea of Government-Run 5G Network
FCC Chairman Ajit Pai today said he disagrees with national security advisors' idea that the government should take control of 5G. "I oppose any proposal for the federal government to build and operate a nationwide 5G network," said Pai in a statement.
FCC Says AT&T Can Buy 700 MHz Licenses from Peoples
The FCC has approved AT&T's request to purchase two Lower 700 MHz C Block licenses from Peoples Wireless in Texas. The transaction gives AT&T 24 MHz of contiguous, paired Lower 700 MHz spectrum in two cellular market areas.
FCC Greenlights AT&T Spectrum Deal
The FCC has approved AT&T's request to purchase two Cellular A Block licenses and microwave point-to-point spectrum from Cellular Properties Inc. The spectrum covers 11 counties and parts of two Cellular Market Areas in Illinois.
AT&T Ditching its Band 71 Licenses
AT&T is selling $1 billion worth of recently-acquired radio spectrum licenses to an obscure Virginia company, according to documents filed recently with the FCC. The spectrum in question is all (or nearly all) of the 600 MHz (band 71) licenses that AT&T acquired in an FCC auction just one year ago.
The FCC needs to do their job
Still to me the FCC should have never let the GPS companies to build so reckless to where their signal is pouring over on the L-band, knowing that in the future this spectrum was going to be wanted/needed to be used. SMH.
"Durr.... what's a guard band?" - Julius
The FCC today said that it does not approve of this "guard band" idea, as it leaves too much spectrum unused.
There are two ways to fix this problem. Period.
1) Replace all the cheap, shoddy, accepting-out-of-band-transmissions-as-legiti mate-signals GPS receivers in the world.
2) Increase the guard band size so that cheapskates like Garmin, TomTom and Trimble can keep their lousy second rate radios functioning in the midst of an L-Band LTE rollout.
How crazy is this? "We won't let LightSquared use any of their spectrum unless they can use all of it!"
