Some Linux, C, Python and DSP skills are necessary. Be prepared to spend a night or more only to get it working. The software is under heavy development, do not expect anything user-friendly.

If you have any information that might help us, let us know.Īudio codec is a work-in-progress and requires a lot of reverse engineering. EADS, ULM/KOBLENZ, Germany: EADS will supply the German Armed Forces (Bundeswehr) with TETRAPOL technology with 30 mobile digital radio systems with 10000. We are trying to reverse-engineer it from hardware implementation, but with no success so far. The encryption algorithm is not known and we would really like to see it and its cryptanalysis. There is no support for encryption - we cannot decrypt the traffic even if you know the key. TETRAPOL is an trunking standard developed by EADS Telecom (Formerly MATRA) and is in use primarally in police and military in Europe. Provides calculations for the design of mobile cellular networks and trunked radio networks for appropriate traffic capacity and Grade of Service. Metadata are available on both unencrypted and encrypted networks, audio only on unencrypted networks. It can decode metadata and there is a very ugly hack for decoding audio. TETRAPOL: FDMA, professional mobile radio system developed by MATRA/EADS. The vehicle adapter and standard TPH700 chargers can be used in non-ATEX environments.Experimental TETRAPOL receiver and decoder. Interoperability between present TETRA, Tetrapol or P25,BB MSs and present. The TPH700 Ex DEFENDING WORLD SECURITY comes with a wide range of ATEXcertifi ed accessories, in particular audio equipment, for a variety of needs. The radio’s shortcut buttons and features are confi gured in such a way that the TPH700 Ex handheld radio is highly suitable for the specifi c needs of different organisations. A high quality loudspeaker provides clear sound, even in noisy surroundings. The high resolution colour display makes information easy to read on a radio that is simple to use and exceptionally intuitive. Its robust design makes it suitable for use in the harshest conditions. ATEX certifi cation, for use in potentially explosive environments, enables users to work in complete safety in places where fl ammable substances are produced, processed, transported and stored.

TETRAPOL TPH700 Ex INTRINSICALLY SAFE HANDHELD RADIO The TETRAPOL TPH700 Ex from CASSIDIAN is designed to provide high quality voice and data communications during critical missions.
