Abstract

An ultra-wideband (UWB) system and method provide a local area network (LAN) and/or LAN access. LAN access versions of the UWB system includes an emulator layer and bridge that allow data to be transmitted between a LAN-UWB hybrid device and a LAN network switch, such as an IEEE 802 network switch, through in part a UWB node of a UWB WPAN that can receive UWB super-frames from the LAN-UWB hybrid device. In some implementations the LAN-UWB hybrid device uses WiFi protocol layers above the emulator layer and a WiNet Peer IP PAL layer below the emulator layer.

Claims

1. A system comprising:

a first device including;

a first portion having a first ultra-wideband radio transceiver configured to transmit routing data in a first ultra-wideband super-frame using a first ultra-wideband band group

a second portion having a second ultra-wideband radio transceiver configured to receive other data in a second ultra-wideband super-frame using a second ultra-wideband band group being different than the first ultra-wideband band group; and

a second device including;

a first portion having a first ultra-wideband radio transceiver configured to receive routing data in the first ultra-band super-frame using the first ultra-wideband band group; and

a second portion configured to maintain routing information based upon routing data received by the first ultra-wideband radio transceiver; and

a third portion having a second ultra-wideband radio transceiver configured to transmit the other data in the second ultra-wideband super-frame using the second ultra-wideband band group based upon the routing information.

2. The system of claim 1 further including an infrastructure network and wherein the first device further includes a third portion configured to extract network addressing instructions from the second ultra-wideband super-frame and a fourth portion to the infrastructure network to provide the network addressing instructions.

3. A system comprising:

a first portion having a first ultra-wideband radio transceiver configured to receive routing data in a first ultra-band super-frame using a first ultra-wideband band group; and

a second portion configured to maintain routing information based upon routing data received by the first ultra-wideband radio transceiver; and

a third portion having a second ultra-wideband radio transceiver configured to transmit the other data in a second ultra-wideband super-frame using a second ultra-wideband band group based upon the routing information, the second ultra-wideband group being different than the first ultra-wideband group.

4. A system comprising:

a first device including;

a first portion having a first radio transceiver configured to transmit routing data using WiFi protocols;

a second portion having a second ultra-wideband radio transceiver configured to receive other data in an ultra-wideband super-frame;

;

and

a second device including;

a second portion configured to maintain routing information based upon routing data received by the first radio transceiver; and

a third portion having a second ultra-wideband radio transceiver configured to transmit the other data in the ultra-wideband super-frame based upon the routing information.

5. A system comprising:

a first portion having a first radio transceiver configured to receive routing data using WiFi protocols; and

a second portion configured to maintain routing information based upon routing data received by the first radio transceiver; and

7. The method of claim 6 further including extracting network addressing instructions from the second ultra-wideband super-frame and providing the network addressing instructions to the infrastructure network.

8. A method comprising:

receiving routing data in a first ultra-band super-frame using a first ultra-wideband band group;

maintaining routing information based upon routing data received by the first ultra-wideband radio transceiver; and

transmitting the other data in a second ultra-wideband super-frame using a second ultra-wideband band group based upon the routing information, the second ultra-wideband group being different than the first ultra-wideband group.

9. A method comprising:
