<p>Das digitale Funksystem TETRA findet weite Verbreitung, nicht nur im BOS-Netz sondern bei zahlreichen Privatfirmen wie z.B. an Flughaefen.</p>
|
|
|
|
<p>Mit ein bisschen Lektuere der Spezifikation und vorhandenen Tools wie gnuradio kann man sich in relativ kurzer Zeit einen "Software Defined Radio" Sniffer fuer die Luftschnittstelle bauen, welcher dann saemtliche Signalisierungsnachrichten und Nutzdaten (z.B. Sprache) mitschneidet. Interpretieren
|
|
kann man die meisten Daten natuerlich nur bei unverschluesselten Netzen - welche aber offensichtlich aus Kostengruenden relativ haeufig vorkommen.</p> </div>
