Abstract: The present invention relates to a wireless personal communications system or WPCS. The system includes at least one radio port (50), at least one radio port controller (60), and at least two subscriber units (20). The system is operable such that: a) two of the subscriber units (20) can communicate with each other directly through one of the radio ports (50); b) two of the subscriber units (20) can communicate with each other via two respective radio ports (50) which are directly coupled by way of a radio port controller (60); and/or c) two of the subscriber units (20) can communicate directly with each other using a walkie-talkie option. The system is also operable so as to allow a plurality of the subscriber units (50) to be individually accessed using a single dialed number.
