DeLink Network

Aviation protected C-Band communication as a service.

About DeLink

DeLink is a decentralized network of ground station transceivers that facilitates Air-to-Ground bi-directional communication links for UAV's operating on aviation protected C-Band.

Offering a decentralized network of ground stations vastly increases the uptake time of BVLOS operations and represents a huge leap forward in migration to C-Band deployments for C2 and DAA.
As one of only two FCC approved providers in the US our airborne and ground units represent the most efficient transition to C-Band for UAV operators.
All of our radio units offer LTE & C-Band as well as ADS-B out.

Airborne DeLink Radios
