PageOutline = OsmocomTETRA Frequently Asked Questions =Can I use OsmocomTETRA to listen to police radio?
No, you cannot. We expect any decent police radio installation to use at least Tetra Air Encryption (TEA1/2/3/4)
or end-to-end encryption.
Also, if this is your interest in this project: Please simply go away, we don't want to talk to you.What can I do using your software?
You can learn more about how TETRA works on its lowest level!How can I actually receive TETRA RF signals?
You can use any radio that is suitable for your target frequency range.
We have so far used the Ettus USRP and USRP2 radios with a variety of different daughter boards.Can your software actually play the voice signal?
Currently we have no support for that. However, a prototype version has been implementedYou are sending GSMTAP messages. Where do I get the TETRA wireshark dissector?
We have not written any TETRA wireshark dissector. Some researcher have done this and
we are trying to convince them to release their code, rather than replicating unnecessary work.
