Broadcasting communicating devices management

A system comprising a gateway manager and gateways connected to the gateway manager, single function devices among communication devices broadcasting messages to gateways, a single function device being only able to broadcast a message including a command, the system comprising:

• the gateways configured to receive messages sent from communication devices, each message containing an identifier of communication device,
• the gateways configured to determine quality metrics for each received message, the quality metrics pertaining to the radio link between the gateway and the communication device,
• the gateways configured to store, for each received message, a property vector comprising the identifier of the communication device and the quality metrics,
• the gateway manager configured to collect the property vectors from all the gateways,
• the gateway manager configured to identify a single function device by detecting a property vector comprising an identifier of communication device that is included in a list of single function devices,
• the gateway manager configured to determine a location of the identified single function device based on the quality metrics of the detected property vector,
• the gateway manager configured to couple the identified single function device with a feedback device, based on the determined location of the single function device and on a location of said feedback device,
• the gateway manager configured to send an order to the coupled feedback device to perform a feedback signal.
