Microwave barrier system

A microwave barrier system, comprising:

• a first microwave barrier comprising a first microwave transmitter and a first microwave receiver, the first microwave transmitter comprising a first electrically tunable microwave generator, the first microwave barrier being configured to be operated at a selectable microwave frequency;
• and
• a second microwave barrier comprising a second microwave transmitter and a second microwave receiver, the second microwave transmitter comprising a second electrically tunable microwave generator, the second microwave barrier being configured to be operated at a selectable microwave frequency,
• wherein the microwave barrier system is configured to:
• determine microwave operating channels in an available frequency range for microwave barriers by means of at least one of the first microwave receiver and the second microwave receiver, and
• assign a respective microwave operating channel to at least one of the first microwave barrier and the second microwave barrier so as to reduce mutual interference between the first microwave barrier and the second microwave barrier,
• wherein the first microwave barrier further comprises a first communication unit configured to signal-couple the first microwave receiver with the first microwave transmitter, wired and/or wireless, to transmit a first microwave operating channel for operation of the first microwave barrier from the first microwave receiver to the first microwave transmitter, and
• wherein the second microwave barrier further comprises a second communication unit configured to signal-couple the second microwave receiver with the second microwave transmitter, wired and/or wireless, to transmit a second microwave operating channel for operation of the second microwave barrier from the second microwave receiver to the second microwave transmitter.
