PageOutline = The Osmocom TETRA project =

This project aims at practical research and experimentation with the [wiki: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 [wiki: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 * forward IP packets contained in TETRA SNDCP to a local {{{tun/tap}}} device

Research on Motorola Dimetra EBTS

We are currently investigating the hardware and software architecture of the [wiki: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.

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.
