Abstract: Authorization data is sent to radio stations so that the radio stations are temporarily authorized, by way of the authorization data, to communicate using radio access technology. Messages can be transmitted between a first radio station and a second radio station via a path that runs via one or more additional radio stations. The authorization data is sent such that, while a message is transmitted via the path using radio access technology, at any point in time a subset of adjacent radio stations on the path are authorized to communicate using radio access technology.
