FCC to Approve 5G Network Despite Military Saying It Will Harm GPS
Arthur T Knackerbracket has found the following story:
The Federal Communications Commission is set to approve a new 5G cellular network despite claims from the Department of Defense that it will interfere with Global Positioning System (GPS) services.
FCC Chairman Ajit Pai today asked fellow commissioners to approve an "application to deploy a low-power terrestrial nationwide network in the L-Band that would primarily support 5G and Internet of Things services." The application is from Ligado, formerly known as LightSquared, which for nearly a decade has sought permission to build a wireless network using frequencies near those used for GPS. A previous failure to obtain FCC approval helped push LightSquared into bankruptcy.
[...] The base-station power reduction is "from 32dBW to 9.8dBW," and Ligado committed to a 23MHz "guard-band using its own licensed spectrum to further separate its terrestrial base station transmissions from neighboring operation," the FCC said.
"As such, Ligado is now only seeking terrestrial use of the 1526-1536MHz, 1627.5-1637.5MHz, and 1646.5-1656.5MHz bands. The Order is conditioned to reflect these technical requirements. It also requires Ligado to protect adjacent band incumbents by reporting its base station locations and technical operating parameters to potentially affected government and industry stakeholders prior to commencing operations, continuously monitoring the transmit power of its base station sites, and complying with procedures and actions for responding to credible reports of interference, including rapid shutdown of operations where warranted," the FCC said.
[...] Ligado previously planned a 4G network, but the years-long delay resulted in the switch to 5G.
