End-to-End RAN
Includes RUs, DUs, CUs, and UE Aircards Patented Technologies. Proven to solve long-range, high-speed, and interference challenges

Cloud-Native & Scalable
Flexible architecture supporting seamless expansion

Deployed at Scale
Powering Gogo’s ATG network across North America

How It Works:
Ground stations connect to aircraft using advanced Open RAN radio units optimized for long-range and velocity to deliver carrier-grade 5G. Proprietary algorithms handle Doppler compensation, beamforming, and interference management, enabling stable throughput at altitude.

Key Benefits

  • Spectrum reuse from terrestrial wireless bands and satellite uplink bands possible on a non-interference basis
  • Support for both tdd and fdd in any sub 6ghz band
  • ATG ground networks can be deployed at a fraction of the cost of satellite systems
  • Scalable architecture allows densification for higher capacity in high traffic areas & corridors
  • Low cost, lightweight certified airborne equipment with simple installations
  • Supports commercial, business and general aviation
