Operating principle 1

Radio station 8 sends a message to Radio station 3, which is about 150 km away and there is no direct connection, as the distance is greater than a coverage. SecureChat system finds a route to deliver the message from 8 to 3, using following stations on a route as relays 8(sender)->4->1->10->12->3 (receiver).

 

Operating principle 2

Radio station 3 sends a reply to 8. They are out of each others coverage. After receiving the last message from 8, the stations 1 and 4 are out of order and the same route can not be used. SecureChat finds automaticly a new route for the message using following stations 3 (sender)->12->10->5->6->8 (receiver).
