Radio-communication system resistant to radio disturbances

A method for radio-communication between a primary communication device and at least one secondary communication device the primary device may be configured to become a secondary device and vice versa, the method using an application carrier frequency for the transmission of an application datum, the method being executed by the primary communication device and comprising the following steps:

• receiving a piece of information BER relating to a quality of a communication link on at least one network carrier frequency comprised in a group of carrier frequencies originating from the at least one secondary communication device;
• carrying out a diagnostic of communication based on the information BER relating to the quality of the communication link on the at least one network carrier frequency;
• extracting a subgroup of carrier frequencies likely to become application carrier frequencies and carry a signal to be transmitted from the group of carrier frequencies;
• selecting the application carrier frequency in the subgroup of carrier frequencies;
• establishing an application communication between the primary communication device and the at least one secondary communication device on the application carrier frequency.
