Abstract

An apparatus for transmitting signals between UWB networks is disclosed, which comprises: a signal converter for converting received optical signals from another UWB network into UWB signals, transmitting the converted optical signals within a UWB network, and converting UWB signals generated from within the UWB network into optical signals; and an optical signal transmission means for directing the received optical signals the signal converter and a further UWB network.

Claims

1-4. -4. (canceled)

5. An apparatus for transmitting signals between a central station and a plurality of picocells within a UWB network, comprising:

an optical switch for transmitting one portion of received optical signals from the central office or the plurality of picocells within the UWB network to a signal converter and another portion of the received optical signals to a second picocell, wherein the signal converter converts the received optical signals into UWB signals, transmits said converted optical signals downstream to a first picocell, and converts UWB signals generated within the first picocell into optical signals.

6. The apparatus as claimed in claim 5, wherein the optical switch includes a controller.

7. The apparatus as claimed in claim 5, wherein the optical switch stores a predetermined identification number and transmits the received optical signal to the signal converter only when a destination identification number in the received optical signal corresponds to the predetermined identification number.

8. The apparatus as claimed in claim 5, wherein the optical switch is a passive device.

9. The apparatus as claimed in claim 8, wherein the optical switch further includes sensors for controlling communication between each picocells in the UWB network.

10. The apparatus as claimed in claim 8, wherein the optical switch further configured for CSMA/CA method for controlling communication between each picocell in the UWB network.
