Multipurpose Radio Server (MRS)
Multipurpose Radio Server is an offline-first connectivity and reconnaissance hub designed for isolated environments.
Compact communication and information exchange server on Raspberry Pi for service-denied areas. Ideal for disasters, unserviced environments, long-range tracking, and offline-first operations.
Overview
MRS provides a modular, hardware-focused foundation that interfaces with three supporting layers:
- MRS Core Layer: Connectivity, radio, and reconnaissance tools
- OpenCast Layer: Media casting, control panel, and remote desktop
- AI-harness Layer: AI assistant, knowledge base, and file services
