Inflight internet company Gogo Inc. will build an air-to-ground 5G network for business and commercial aviation.

Gogo will build the 5G network on its existing infrastructure of over 250 towers and will use unlicensed spectrum in the 2.4GHz range, as well as a proprietary modem and advanced beamforming technology, according to a May 29 news release. Gogo expects the network to be available in 2021.

The new network will be designed for use on business aviation aircraft, commercial regional jets and smaller mainline jets operating within the contiguous U.S. and Canada, the company said.
