Encrypted TETRA Networks ?
by Dieter Spaar 09 Sep '13

09 Sep '13

Hello, is anybody aware of encrypted TETRA networks which are not run by the government or police ? I am especially interested about Germany, as far as I am aware all the TETRA networks which use encryption here are the BOS networks. There are of course several networks which use authentication, but no encryption. Best regards, Dieter -- Dieter Spaar, Germany spaar(a)mirider.augusta.de
