    • Systems for connecting telecommunications infrastructure lines to telephones, handsets, computers, telecopy machines and other end user interfaces or consumer electronics devices in a residence or business. Systems according to the present invention include Network Control Units which form the center of a star topology and which communicate via RF link with Wireless Access Units and handsets. Wireless Access Units feature an interface, such as, for example, a standard telephone jack, for accommodating a telephone, a fax machine, 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 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 and provide additional functionality such as entrance monitoring, baby monitoring, HVAC control and other services. Personal Communication Links provide wireless handset and speakerphone services. The Personal Communication Links include independent talk/listen paths from the unit to the Network Control Unit. In addition, each Personal Communication Link includes circuitry for automatically adjusting from high-volume/high-microphone sensitivity for speakerphone operation to low-volume/low-microphone sensitivity for conventional handset operation.

    • The present invention comprises the digital implementation of a spread spectrum communications system including a spread spectrum modulator or transmitter and a spread spectrum receiver or demodulator. The demodulator, as modified with optional techniques, operates at zero I. Under these circumstances the receiver is susceptible to 1/F noise, as well as transient overloads. The addition of a high pass filter stage to only the receiver, in a communication system, without modifying the transmitter, will be recognized by those skilled in the art as violating the basic precepts of communications which attempt to tailor the characteristics of a receiver and transmitter to each other. However the applicant has found that demodulating RZ encoded data with an added high pass filter results in the production of Manchester data which is one of the forms of data encoding that can be handled by the demodulator.

    • A wireless telephone subsystem for coupling line type telephony equipment to the public switched telephone network is described. A base unit is provided which is adapted to be coupled to a plurality of lines of the PSTN. The base unit includes a base coder/decoder which transforms analog signals received from the lines of the PSTN to digital signals and conversely transforms digital signals to analog signals for coupling to the lines of the PSTN. The base unit includes a multiple channel transceiver coupled to the base coder/decoder which responds to the digital signals provided by the base coder/decoder for transmitting those signals by placing selected portions of the digital signals into selected portions of a multiplex frame. The base multiple channel transceiver also receives digital signals and couples those digital signals to the base coder/decoder. Programmable switching is provided to associate selected of the PSTN lines and selected portions of the multiplex frame. The subsystem also includes a wireless interface unit for connecting to the line type telephony equipment. The wireless interface unit also includes a remote coder/decoder for transforming analog signals received from the line type telephony equipment into digital signals and for transforming other digital signals into analog signals for coupling to the line type telephony equipment. The wireless interface also includes a remote transceiver which is coupled to the remote coder/decoder. The remote transceiver responds to digital signals from the remote coder/decoder for transmitting the signals into selected portions of the multiplex frame and receives other digital signals and couples those to the remote coder/decoder.
