[[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 [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.
