The Osmocom TETRA project

This project aims at practical research and experimentation with the TETRA
trunked radio system.

It is part of the bigger family of Osmocom projects,
all aiming to create Free Software (Open Source Software) for mobile communications.

Software Defined Radio TETRA Air interface sniffer

The osmo-tetra project aims at implementing the sending and
receiving part of the TETRA MAC/PHY layer.

Currently, it can
  • receive, demodulate and decode TETRA downlink signals of real-world TETRA networks
  • display information about SYNC, SYSINFO, MM and CMCE PDUs
  • forward those TETRA downlink signals to the wireshark protocol analyzer
    
    h2. Research on Motorola Dimetra EBTS
    
    We are currently investigating the hardware and software architecture of the [[Dimetra_EBTS|Motorola Dimetra EBTS]],
    including its components like Base Radio, Site Controller, etc.
    
    The goal here is to run this equipment without a Motorla [[SwMI]] and thus have an inexpensive platform for running
    your own TETRA network for research purpose.
    
    h2. Applied Research on security of real-world TETRA networks
    
    Using the tools we develop, we are analyzing the security of real-world TETRA networks.
    
    Our experience so far is quite shocking: All the non-government TETRA networks that we
    have encountered use no TETRA encryption at all, i.e. they are subject to very easy
    eavesdropping attacks.
    
    More information will follow soon.
