Abstract: A wireless communication network system apparatus which provides for isochronous data transfer between node devices of the network, which provides at least one master node device which manages the data transmission between the other node devices of the network, which avoids or reduces interference from other wireless products and which resolves random errors associated with wireless technology including multipath fading. The system provides a communication protocol which shares the wireless transport medium between the node devices of the network, and which provides each node device on the network a designated transmit time slot for data communication.

Abstract: A broadband transmit/recieve antenna apparatus which operates at high frequencies and provides for two separate wideband tapered notch regions formed on one coplanar substrate. The tapered notch regions function as radiators for the transmission and reception of electromagnetic signals. The simple and compact design for the broadband antenna permits the transmission and reception of high frequency omnidirectional or directional radiation patterns. The broadband antenna interfaces with an an integrated circuit such as an ASIC which provides a series of pulsed signals and is resident on the antenna. The design of the broadband antenna provides for an optional stop notch to separate the transmitting portion of the antenna from the receiving portion of the antenna. Additionally, the antenna provides for impedance matching by locating transmission lines at an appropriate location with respect to the tapered notch radiators.

Abstract: A base band receiver apparatus comprising an RF front end section, a pulse detection unit wherein modulated, ultra-short spread spectrum pulses are detected, and a data recovery unit wherein clock and data recovery from the detected pulses are carried out. The RF front end includes an antenna and circuitry for filtering and amplifying RF signals received by the antenna. The pulse detection unit preferably includes a tunnel diode or Schottky diode which rectifies the incoming voltage signals from the RF front end and provides a power envelope, a high pass filter which removes residual DC offset from the voltage signals, and a comparator which provides threshold voltage detection.
