Abstract

A method and device for transmitting information over a first medium include allocating for signal transmission, each of a plurality of frequency sub-bands of an ultra-wide band spectrum and sending over the first medium an ultra-wide band transmission including the information. The ultra-wide band transmission is performed by sending a signal over each of the plurality of frequency sub-bands. Each signal may be encoded, modulated and/or multiplexed. The information which is transmitted may be obtained from a second signal transmission received over a second medium.

Claims

1. A method for transmitting information over a first medium, comprising:

providing a first transceiver configured for UWB communications over the first medium;

providing a second transceiver configured for UWB communications over a second medium, the second transceiver interfaced to the first transceiver;

receiving at the second transceiver an incoming UWB communication having a first type of encoding and a first type of modulation;

communicating information from the incoming UWB communication to the first transceiver;

allocating for signal transmission by the first transceiver, a plurality of frequency sub-bands of an ultra-wide band spectrum;

forming an ultra-wide band transmission from a plurality of signals, each of the signals associated with one of the plurality of frequency sub-bands, the ultra-wide band transmission including the information for transmission over the first medium; and

sending over the first medium the ultra-wide band transmission including the information, the ultra-wide transmission having, a second type of encoding and a second type of modulation, the second type of encoding different from the first type of encoding and the second type of modulation different from the first type of modulation.

2. The method of claim 1 wherein the step of sending is sending over the first medium is sending over air in a wireless transmission.

3. The method of claim 1 wherein the step of sending is sending over a guided medium.

4. The step of claim 3 wherein the guided medium is an electrically conductive guided medium.

5. The method of claim 4 wherein the electrically conductive guided medium is selected from the set consisting of an un-bonded telephone twisted pair medium, a bonded telephone twisted pair medium, a coaxial cable medium, a power line medium, a shielded pair wire medium, a metallic vehicle body medium, a structural steel medium, a railroad rail medium, a reinforcing bar medium, a metallic pipe medium, a metal desk medium, and a computer backplane medium.

6. The method of claim 1 wherein the second medium is of a type different from the first medium.

7. The method of claim 6 wherein the second medium is a guided media and the first medium is a non-guided medium.

8. The method of claim 6 wherein the second medium is a non-guided media and the first medium is a guided medium.

9. The method of claim 6 wherein the first medium is an electrically conductive medium and the second medium is air.

10. The method of claim 6 wherein the first medium is air and the second medium is an electrically conductive medium.
