Problem
Terrestrial mobile networks cannot reach remote or underserved areas, and existing satellite communication solutions often require dedicated hardware, lack integration with 5G standards, and support only a single operator, limiting scalability and cost‑effectiveness.
Solution
Celeste Technologies offers SmartgNB, a fully software‑defined 5G non‑terrestrial network (NTN) base station that runs on commercial off‑the‑shelf (COTS) hardware. The product is 3GPP Release 17 compliant, platform‑agnostic, and capable of serving multiple operators, enabling satellites to provide direct‑to‑device voice, SMS, and data services. By delivering the gNB functionality as software, operators can license, customize, or integrate the solution into existing satellite payloads, extending coverage where terrestrial infrastructure ends while reducing total cost of ownership.
Target Audience
Primary customers are satellite operators and mobile network operators seeking to extend 5G coverage to remote, maritime, or disaster‑affected areas without deploying dedicated ground infrastructure.
Features
- 100 % software implementation of a 5G NR gNB for NTN, eliminating the need for specialized satellite hardware
