Ultra wide band communication systems and methods

The present invention is a receiver having a radio frequency (RF) front end, a pulse detector operatively coupled to the RF front end, and a data recovery unit operatively coupled to the pulse detector. The data recovery unit is configured to receive spread spectrum RF signals having different pulse repetition frequencies and using different modulation techniques. The receiver may operate in conjunction with a transmitter as a transceiver. The receiver may also operate in a networked environment in which a network of transceiver node devices comprise a first slave transceiver having a receiver configured to receive spread spectrum signals, and a second slave transceiver configured to communicate with the first slave transceiver. Additionally, a master transceiver is in communication with the first slave transceiver and the second slave transceiver. The master transceiver is configured to manage data transmissions and synchronization between the first slave transceiver and the second slave transceiver.

Ultra wide band base band receiver

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.
