摘要

5 WIRELESS COMMUNICATION DEVICE AND METHOD, AND SYSTEM COMPRISING SUCH A DEVICE The gateway communication device for wireless communication networks receives 10 messages from a low-power transmitter (I) and communicates with a network (5). In a system comprising several gateway devices for a low-power transmitter (1), a master gateway device is defined. Definition of a master gateway device is based on reception quality indicators (RQI) of the gateway devices situated in said reception zone (A) of messages transmitted by said low-power transmitter (1). The gateway device having the 15 highest reception quality indicator (RQI) is selected to be said master gateway device (6M). The communication method also defines a master gateway device in the same way. The master gateway device then selects a backup gateway device (6B) to store link tables and in certain cases to act in the place of the master.
