| 2 | = OsmocomTETRA Frequently Asked Questions = |
||
| 3 | |||
| 4 | == Can I use OsmocomTETRA to listen to police radio? == |
||
| 5 | |||
| 6 | No, you cannot. We expect any decent police radio installation to use at least Tetra Air Encryption (TEA1/2/3/4) |
||
| 7 | or end-to-end encryption. |
||
| 8 | |||
| 9 | Also, if this is your interest in this project: Please simply go away, we don't want to talk to you. |
||
| 10 | |||
| 11 | == What can I do using your software? == |
||
| 12 | |||
| 13 | You can learn more about how TETRA works on its lowest level! |
||
| 14 | |||
| 15 | == How can I actually receive TETRA RF signals? == |
||
| 16 | |||
| 17 | You can use any radio that is suitable for your target frequency range. |
||
| 18 | |||
| 19 | 2 | laforge | We have so far used the Ettus USRP and USRP2 radios with a variety of different daughter boards, as |
| 20 | well as the [wiki:Funcube_Dongle] Pro. |
||
| 21 | 1 | laforge | |
| 22 | == Can your software actually play the voice signal? == |
||
| 23 | |||
| 24 | 2 | laforge | Currently we have no support for that. However, a yet unreleased proof-of-concept version exists. |
| 25 | 1 | laforge | |
| 26 | == You are sending GSMTAP messages. Where do I get the TETRA wireshark dissector? == |
||
| 27 | |||
| 28 | 3 | laforge | We have not written any TETRA wireshark dissector. Researchers in China have done this and |
| 29 | we have convinced them to release their code under GNU GPL, rather than replicating unnecessary work. |
||
| 30 | |||
| 31 | This code has since been merged into the official wireshark source code repository, as released by |
||
| 32 | wireshark.org. However, we are not sure if any release was made after it had been merged, so you are |
||
| 33 | advised to use the latest svn repository from wireshark.org. |
