Gogo Warns of Interference Threat to ATG From 900 MHz Realignment

Gogo said mobile broadband operations introduced in 900 MHz mustn't cause harmful interference to air-to-ground radiotelephone service (ATG) in the adjacent 894-896 MHz. The FCC is looking at reconfiguring the 900 MHz band to allow broadband (see 1907030028). “Gogo’s engineering analysis shows that even a single mobile broadband device transmitting in the 900 MHz band within one kilometer of a Gogo base station can cause adjacent band interference with ATG base station receivers,” it filed, posted Thursday in docket 17-200: “This interference will either reduce the receive range of Gogo’s base stations or the capacity of ATG links.” The company urged protecting ATG with safeguards proposed for adjacent licensees in 901-902, 930-931 and 940-941 MHz.
