Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
