COMMUNICATION SYSTEM WITH AN EXTENDED COVERAGE AREA

摘要

A radio communication system (20) is described having a primary-secondary star-like topology, and wherein further secondary stations/devices (24) located outside of the radio coverage area (13) of the primary station are enabled to communicate with the primary station (12) via a first secondary station (22) located within the coverage area of the primary station (12). This is achieved by the first secondary station (22) registering the further secondary station(s) with both itself and the primary station (12), following which messages are exchanged between the primary station and the further secondary station(s) via the first secondary station according to translation of identity codes allocated at the time of registration.
