Abstract

The system has a number of remote signal generators (1-7) that communicate bidirectionally with a central station (12) via a number of substations (8-11). Each of the substations is also in bidirectional contact with each other. A number of substations (9-11) may be in direct contact with the central station. The mode of communication is determined by a Received-Signal-Strength-Indicator (RSSI) table which defines channel quality and synchronises substations with central station. The communication channels are constantly monitored, and transmission quality is measured and stored on a microcomputer system of the central station.
