The present invention describes a network communication system which includes a first slave transceiver configured to communicate a plurality of TDMA data packets at different data rates to a second slave transceiver. The second slave transceiver is also configured to communicate a plurality of TDMA data packets at different data rates to the first slave transceiver. A master transceiver manages data communications between the first slave transceiver and the second slave transceiver. Each transceiver includes a data modulation unit, a transmitter, an antenna, and a receiver. The data modulation unit is configured to generate a plurality of signals having variable pulse repetition frequencies and different modulation techniques. The transmitter is coupled to the data modulation unit and the transmitter is configured to generate a pulse stream according to the data modulation unit. The transmitting antenna is coupled to the transmitter and the transmitting antenna is configured to transmit a plurality of ultra wide band base band signals. The receiver is configured to detect and demodulate said ultra wide band base band signals operating at variable pulse repetition frequencies and having different modulation methods.

DETAILED DESCRIPTION The present invention describes a network communication system which includes a first slave transceiver configured to communicate a plurality of Time Division Multiple Access (TDMA) data packets at different data rates to a second slave transceiver.
The second slave transceiver is also configured to communicate a plurality of TDMA data packets at different data rates to the first slave transceiver.
A master transceiver manages data communications between the first slave transceiver and the second slave transceiver.
Each transceiver includes a data modulation unit, a transmitter unit, an antenna, and a receiver.
The data modulation unit is configured to generate a plurality of signals having variable pulse repetition frequencies and different modulation techniques.
The transmitter unit is coupled to the data modulation unit and the transmitter unit is configured to generate a pulse stream according to the data modulation unit.
The transmitting antenna is coupled to the transmitter unit and the transmitting antenna is configured to transmit a plurality of ultra wide band base band signals.
The receiver is configured to detect and demodulate the ultra wide band base band signals operating at variable pulse repetition frequencies and having different modulation methods.
The present invention provides a system and method for low bit-rate devices to communicate with high bit-rate devices.
The present invention also provides a system and method for devices operating with different modulation techniques to communicate with one another.
The present system and method provides a TDMA system and method that allows sharing a wireless medium with devices capable of transmitting and receiving at different data rates.
The system and method are particularly applicable to base band spread spectrum networks, also referred to herein as ultra-wide band networks.
The system of the preferred embodiment comprises a network of transceiver node devices.
Each transceiver transmits and receives data
