= 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 [http://osmocom.org/ 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 [http://wireshark.org/ 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.
