TetraSpot

TETRA base station (hotspot)

A homebrew TETRA base station that fits on a desk. The first amateur project in the world to bring a home TETRA base station to full functionality.

What it does

  • Group and individual calls like on a real network
  • Messaging and terminal locations on a map
  • Bridges your radios into the nationwide TetraPoland network
  • Runs on a single small computer

A TETRA base station normally means a rack of equipment and a budget no radio amateur has. TetraSpot brings it down to one small computer on a desk — and one that behaves like a real network: terminals see it, register to it and talk through it exactly as they would through professional infrastructure.

What it does

  • Broadcasts as a valid TETRA network — terminals find it and register
  • Group and individual calls, including simultaneous two-way
  • Floor control for half-duplex conversations
  • Individual and group text messages, with store-and-forward delivery
  • Terminal location — live positions on a map
  • Optional authentication with a list of permitted terminals
  • Over-the-air rekeying
  • Dynamic talkgroup assignment
  • Telephone gateway — calls to and from the phone network
  • Browser management panel: live view, call logs and configuration

In development

  • Support for several base stations at once
  • Packet data
  • Retransmission of lost fragments
