Testing Shows LightSquared's Network Messes with GPS
A preliminary report has found that using L-Band spectrum, as LightSquared hopes to for its forthcoming Long Term Evolution network, does in fact interfere with neighboring GPS services. The findings spell trouble for LightSquared. In January, the Federal Communications Commission ruled that LightSquared could use its L-Band spectrum for terrestrial purposes if it could prove it wouldn't interfere with GPS systems. Public safety and other agencies in the test region of New Mexico indicated that their GPS systems were disabled and/or knocked out as far away as 20 miles from a single LightSquared tower. LightSquared wants to install more than 36,000 towers across the U.S. to deliver wholesale LTE broadband services. "LightSquared and GPS can and will be able to coexist peacefully," said Jeff Carlisle, LightSquared's executive vice president for regulatory affairs and public policy. "We're committed to identifying and resolving the issues through this process." The company is scheduled to deliver a final report to the FCC on the matter later this month. If the interference issues cannot be resolved, it puts LightSquared's business in jeopardy.
AT&T Wants LTE-U Opponents to Agree to Play Fair
Joan Marsh, AT&T's vice president of federal and regulatory affairs, today prosed that the FCC use existing rules to help organizations on opposite sides of the LTE-U debate find some middle ground. LTE-U is the use of LTE services over unlicensed spectrum, or WiFi frequencies.
Verizon To Test Spectrum Sharing in Military Radar Band
Verizon, Ericsson, and Qualcomm recently announced plans to test spectrum-sharing technology in the 3.5 GHz band. The band is used for military radar systems, but the FCC believes the band can be shared with commercial uses in some situations.
Court: FCC Allowed to Manage Tower Siting Process
An appeals court sided with the FCC recently in a decision that upholds the agency's authority to accelerate the process of gaining local approval for cell towers. The U.S.
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 Relaxes Rules Governing 800 MHz Spectrum
The FCC this week made it easier for carriers to add LTE to their 800 MHz spectrum holdings. Rules concerning the 800 MHz band (CDMA Band Class 0, LTE Band 5) have been in place since 1981 and limit how much power carriers can use to transmit wireless signals across those airwaves.
Good-Bye Light Squared and...
This is more reason to understand that a carrier can't just waltz into this industry and perform a start up to compete against the top two. There is very little spectrum left and ATT wants to grab the last of it from T-mobile.
Those for this merge, gravely misunderstand the detrimental effects of it.
