LightSquared's Network Wrecks GPS, Says Gov. Study
A recent test conducted by the U.S. government concludes that LightSquared's proposed Long Term Evolution 4G network "caused harmful interference to majority of GPS receivers tested," according to a portion of the study, which was provided to Bloomberg. "No additional testing is required to confirm harmful interference exists." In January, the Federal Communications Commission gave LightSquared provisional permission to operate its LTE network in the L-Band satellite spectrum — if it could prove that it wouldn't interfere with nearby GPS signals. LightSquared, several arms of the U.S. government, and private companies have all tested the network extensively throughout the course of 2011. While tests have shown repeatedly that LightSquared's network interferes with GPS — including those receivers in airplanes and other military equipment — LightSquared has proposed several alterations that it says should fix the problem. It has proposed to use a lower channel in its spectrum holdings, as well as ramp down the power of its amplifiers. Martin Harriman, LightSquared's executive vice president of ecosystem development and satellite business, said in a statement issued Friday, "The statement that testing shows that most GPS devices would be disrupted by LightSquared’s operation is patently false. There is no way that such a conclusion could be drawn without deliberately ignoring a critical element in LightSquared’s mitigation proposal to manage the power from its network that GPS devices will be able to receive." LightSquared has consistently accused the GPS industry of encroaching on LightSquared's spectrum with shoddy GPS designs. LightSquared says its LTE service will start at $7 per gigabyte of mobile broadband, less than half what the competition charges. LightSquared has also signed up 30 wholesale partners to resell its network services under their own brands. U.S. officials are meeting this week to make a decision on the matter.
FCC Gives Verizon and Qualcomm Permission to Test LTE-U
The FCC is allowing Verizon and Qualcomm to move forward with limited tests of LTE in unlicensed spectrum bands generally reserved for WiFi. Specifically, the companies are being allowed to perform small-scale tests at two Verizon facilities, one in Oklahoma City, Okla., and the other in Raleigh, N.C.
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.
Verizon Explains Why It Is Refarming PCS Spectrum
Verizon Wireless elaborated today on news it has begun to refarm its PCS spectrum for LTE. Verizon has already deployed LTE on its PCS spectrum in a limited scale across Manhattan and Cleveland, Ohio, with "about 10 other markets" currently in testing.
AT&T Finally Using WCS Spectrum for LTE; Will Test LTE-U
AT&T has begun deploying LTE on its 2.3GHz WCS spectrum in a handful of markets around the country. Earlier this year, AT&T said it would begin the deployment by summer, and it is just meeting that commitment.
AT&T Stepping Up Three-Channel Carrier Aggregation
AT&T today confirmed to Fierce Wireless that, like its competitors, it is deploying three-channel carrier aggregation on its LTE 4G network. "We're currently in the process of deploying three-way carrier aggregation on our network," said AT&T spokesman Steven Schwadron in a statement given to Fierce.
Why did the government sell it to lightquared?
It's also pretty cool that the government charges GPS manugacturers NOTHING to use the signal.
Take a look into the financials and when the FCC granted the modification of the rules to allow LS to use the spectrum for terrestrial communication.
The original spectrum deal did not include terrestrial communication devices.
LightSquared's Spectrum MURDERS GPS, causing GPS related funerals across the nation. I really hope that the westboro baptist church does not stage a protest, becuase as we all know, God loves dead GPS!
