Abstract
Systems for connecting telecommunications infrastructure lines (640) to telephones, handsets (300), computers (200), telecopy machines (400) and other end user interfaces or consumer electronics devices in a residence or business. Systems according to the present invention include Network Control Units (100) which form the center of a star topology and which communicate via RF link with Wireless Access Units (200) and handsets (300). Wireless Access Units feature an interface, such as, for example, a standard telephone jack, for accommodating a telephone, a fax machine (400), a compute modem or other device. Computers or other devices may also be accommodated by Wireless Access Units having other physical and virtual interfaces, including, for instance, serial ports (200) or network interfaces. The Wireless Access Units may also be digital to accommodate ISDN or any other digital standard. Wireless control/monitoring accessories may also be employed to communicate with the Network Control Unit (100) and provide additional functionality such as entrance monitoring, baby monitoring, HVAC control and other services.
