摘要： An intra-premises communication system enables the use of a preinstalled wired transmission channels, yet allowing a particular communication system to be located at a desired region in the premises. The system comprises an exchange box adapted to be installed in the premises and provided with different interfaces for connection to different networks. A plurality of the wired transmission channels extend from the exchange box and terminate to receptacles which are installed in the premises and have common connectors. A plurality of indoor wireless terminals of different types are provided for use within the premises. A plurality of local transmitter-receivers of different types are provided in correspondence to the types of the wireless terminals. Each of the local transmitter-receivers is detachably and selectively mounted to the common connector of the receptacle for wired communication with one of the networks through the associated transmission channel. The local transmitter-receivers have individual antennas or the like member for wireless communication with at least one of the terminals. The exchange box includes a switch for connecting the transmission channels selectively to particular ones of the interfaces, thereby allocating local transmitter-receivers and the associated terminals to the different networks. The receptacles can be preinstalled in the like fashion as the conventional electrical receptacles so that a desired wireless communication system can be located at a suitable region simply by mounting the local transmitter-receiver of the selected type to the common connector of the receptacle.
