{{>toc}} h1. [[PageOutline]] = The Osmocom TETRA project = This project aims at practical research and experimentation with the [[TETRA]] [wiki:TETRA] trunked radio system. It is part of the bigger family of "Osmocom":http://osmocom.org/ [http://osmocom.org/ Osmocom] projects, all aiming to create Free Software (Open Source Software) for mobile communications. [[BlogList(format=float,recent=5,max_size=350)]] *NOTE: '''NOTE: Please observe the [[Legal_Notes]]* [wiki:Legal_Notes]''' before using this software! h2. == Software Defined Radio TETRA Air interface sniffer == The [[osmo-tetra]] [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":http://wireshark.org/ [http://wireshark.org/ wireshark] protocol analyzer <pre> h2. * 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 [[Dimetra_EBTS|Motorola [wiki:Dimetra_EBTS Motorola Dimetra EBTS]], EBTS], including its components like Base Radio, Site Controller, etc. The goal here is to run this equipment without a Motorla [[SwMI]] 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. h2. == Osmocom TETRA software == * [[osmo-tetra]] [wiki:osmo-tetra] - Our software defined radio TETRA receiver h2. == TETRA related hardware == * [[Funcube_Dongle]] [wiki:Funcube_Dongle] - A small receiver that can be used with [[osmo-tetra]] [wiki:osmo-tetra] * [[Dimetra_EBTS]] [wiki:Dimetra_EBTS] - Information on the Motorola Dimetra EBTS * [[Rohde_Schwarz_BSC411]] [wiki:Rohde_Schwarz_BSC411] - Information on the R&S BICK TETRA BSC * [[Rohde_Schwarz_TOB500]] [wiki:Rohde_Schwarz_TOB500] - Information on the R&S BICK TETRA Outdoor BTS 500 * [[Antenna_LNA]] [wiki:Antenna_LNA] - Antenna and LNAs suitable for TETRA h2. == Press Coverage == * http://www.h-online.com/security/news/item/TETRA-digital-radio-now-for-everyone-1254088.html * http://www.heise.de/newsticker/meldung/TETRA-Digitalfunk-fuer-jedermann-1253092.html * http://www.golem.de/1101/80600.html (German) * http://infosecurity.ch/20110123/tetra-hacking-is-coming-osmocomtetra/ h1. = Further Reading = * [[FAQ]] [wiki:FAQ] - Our Frequently Asked Questions * [[Recommended_Reading]] [wiki:Recommended_Reading] -- Links to recommended books, articles, etc. * [[TETRA_in_Germany]] [wiki:TETRA_in_Germany] -- Information we collect about TETRA networks in Germany * [[Talks_Lectures]] [wiki:Talks_Lectures] -- Talks / Lectures given by the osmocomTETRA project * [[Speech_Codec]] [wiki:Speech_Codec] -- Information on how to find specs + reference code of the TETRA speech codec * [[Test_Samples]] [wiki:Test_Samples] -- Samples recorded on test network
