Abstract

A radio transceiver device includes circuitry for radiating electromagnetic signals at a very high radio frequency both through space, as well as through wave guides that are formed within a substrate material. In one embodiment, the substrate comprises a dielectric substrate formed within a board, for example, a printed circuit board. In another embodiment of the invention, the wave guide is formed within a die of an integrated circuit radio transceiver. A plurality of transceivers with different functionality is defined. Substrate transceivers are operable to transmit through the wave guides, while local transceivers are operable to produce very short range wireless transmissions through space. A third and final transceiver is a typical wireless transceiver for communication with remote (non-local to the device) transceivers.

Claims

1. A method for communicating within a device, comprising:

generating, in a first local transceiver of an integrated circuit located within the device, a first wireless radio frequency (RF) communication signal for wireless transmission to a second local transceiver also located within the device, the first wireless RF communication signal including at least one of an address or an ID of the second local transceiver;

determining whether to transmit the first wireless RF communication signal directly to the second local transceiver via a first communication link or to a third local transceiver, also located within the device, for forwarding to the second local transceiver as a second wireless RF communication signal via a second communication link based on at least one of the address or ID provided to the third local transceiver; and

wherein at least one of the first and second wireless RF communication signals is transmitted wirelessly through a substrate of the device and within an isolating boundary that forms a wave guide to channel wireless communication within the substrate through the wave guide, and in which the substrate is utilized as a communication link for RF signals and the isolating boundary that forms the wave guide isolates at least one of the first and second wireless RF communication signals transmitted wirelessly through the wave guide from other RF signals transmitted within the substrate.

2. The method of claim 1 wherein the determining whether to transmit the first wireless RF communication signal to the third local transceiver is based upon instantaneous loading conditions of the first local transceiver.

3. The method of claim 2 further including receiving loading information that reflects loading of the communication links within the device.

4. The method of claim 1 further including transmitting over the first communication link that is through a first substrate or transmitting over the second communication link that is disposed on a second substrate.

5. The method of claim 1 wherein the first and second communication links reside on a same substrate of an integrated circuit.

6. The method of claim 1 wherein the first and second communication links reside on a same substrate of a board.

7. The method of claim 1 wherein the first and second communication links are disposed in different substrates on separate boards within the device.

8. An apparatus, comprising:

a plurality of local transceivers operable to forward wireless radio frequency (RF) communications as nodes in a mesh network within a device, wherein each node forms a wireless communication link with at least one other node within the device to forward communications; and

wherein a first local transceiver of the plurality of local transceivers is operable to transmit a first wireless RF communication signal directly to a second local transceiver via a first communication link or to a third local transceiver for forwarding to the second local transceiver as a second wireless RF communication signal via a second communication link based on at least one of an address or ID of the second local transceiver provided to the third local transceiver, in which at least one of the first and second communication links resides within a substrate and within an isolating boundary that forms a wave guide to channel wireless communication within the substrate through the wave guide, and in which the substrate is utilized as a communication link for RF signals and the isolating boundary that forms the wave guide isolates at least one of the first and second wireless RF communication signals transmitted wirelessly through the wave guide from other RF signals transmitted within the substrate.

9. The apparatus of claim 8 wherein the first and second communication links are disposed on separate substrates.

10. The apparatus of claim 9 wherein the separate substrates are disposed on separate integrated circuits that reside on a same board.

11. The apparatus of claim 9 wherein the separate substrates are disposed on separate integrated circuits that reside respectively on different boards.

12. The apparatus of claim 9 wherein the first local transceiver is operable to select the first or second communication link based upon a loading condition.

13. The apparatus of claim 12 wherein the loading condition pertains to loading of at least one integrated circuit.

14. The apparatus of claim 12 wherein the loading condition pertains to loading of at least one communication link.

15. The apparatus of claim 8 wherein communication paths between specified local transceivers are statically specified.

16. The apparatus of claim 8 wherein communication paths between specified local transceivers are dynamically determined based upon loading conditions.
