More Interference for LightSquared's Planned Network
A new set of government tests has confirmed the results of earlier tests showing that LightSquared's use of L-band spectrum to operate a Long Term Evolution data network does in fact interfere with nearby GPS services. The new test said LightSquared's network disrupted service to all GPS devices in the test area. For example, General Motors indicated that its OnStar service was degraded significantly by LightSquared's network, and the Federal Aviation Administration said that LightSquared's network reduces the functionality of GPS systems used by aircraft to roughly zero when they are flying below 2,000 feet. The Defense Department said LightSquared's network can interfere with military equipment and military aircraft. The Federal Communications Commission gave LightSquared permission to use the L-band spectrum in January pending the results of interference tests. LightSquared and the GPS industry plan a last set of tests next week. LightSquared believes it can adjust its network so that it won't interfere with GPS systems.
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.
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.
T-Mobile Claims 5G Tests Reach 12 Gbps
T-Mobile and Ericsson today said lab tests demonstrate the power of forthcoming 5G technology. The two firms pushed data speeds to 12 Gbps over a wireless connection, with latency as low as 2 milliseconds, in the 28 GHz band.
