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. |
||

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. |

22 | == Can your software actually play the voice signal? == |
||
23 | |||

26 | == You are sending GSMTAP messages. Where do I get the TETRA wireshark dissector? == |
||
27 | |||
28 | We have not written any TETRA wireshark dissector. Some researcher have done this and |
||
29 | we are trying to convince them to release their code, rather than replicating unnecessary work. |
