In-flight Wi-Fi provider Gogo is building a 5G network across the US and Canada, giving passengers access to faster speeds and lower latency connectivity while in the air.

Gogo will upgrade its existing Air-to-Ground (ATG) network, which comprises more than 250 towers across North America, and use unlicensed spectrum in the 2.4GHz band. The company will also use a proprietary modem and beamforming technology to improve the quality of the signal.
