Gogo Raises Red Flags on Use of Power Spectral Density Measurements in Cellular Band
Given the risk of air-to-ground (ATG) interference, the FCC should make cellular operators work out mitigation agreements or coordinate with adjacent channel licensees before starting operations at higher power levels using any power spectral density (PSD) models, Gogo said in…

an ex parte filing posted Friday in docket 12-40. Cellular operators also should be required to adopt stronger out-of-band-emission (OOBE) limits on cellular operations near 800 MHz ATG base stations, Gogo said. AT&T has been pushing for use of PSD models in complying with the FCC's radiated power limits for 800 MHz cellular operations in parts of Missouri (see 1504130031). That idea also has Verizon support (see 1508120057). While the 800 MHz band should be used, operations there based around PSD models also raise the risk of OOBE interference to the adjacent 800 MHz ATG band, which could affect in-flight broadband services, Gogo said.
