where every second counts

The Sybet SpellCom system is a specialized, portable wireless communication solution engineered for the most challenging subterranean environments. Specifically designed for cave exploration, tunneling, and rescue operations, SpellCom ensures that teams remain connected where traditional radio and cellular signals fail.

The system operates on a decentralized, self-healing mesh network that is as rugged as the terrain it inhabits.

•    mPhone (Radiotelephone): A durable, handheld device that serves as the primary communication tool for field personnel. It supports individual and group voice calls, text data transmission, and real-time location tracking.

•    MiniNode (Wireless Network Node): These lightweight, battery-operated units (approx. 500g) act as the backbone of the system. Placed at intervals of roughly 50 meters, they automatically form an ad-hoc mesh network to extend coverage deep into tunnels or cave systems.
