Abstract

A method and apparatus are provided for establishing wireless communications between standardized and non-standardized information devices. In association with a network of standardized information devices, a virtual network is formed which includes a virtual node representing each of the non-standardized information devices.

Claims

1. A wireless information system for wireless communication with at least one non-standardized node adapted for communication in a communication/protocol compatible with the respective at least one non-standardized node and not adapted for communication with other nodes in accordance with a common standard and having a transceiver, wherein said non-standardized node lacks computing capability sufficient to communicate in accordance with said common standard, and said system includes:

a. standardized network including a bus for carrying communications between any standardized nodes that are connected to the bus, said any standardized nodes being adapted for communicating wit other nodes in accordance with said common standard;

b. a wireless station including a transceiver for wireless communication with the at least one non-standardized node;

c. a virtual network coupled to the wireless station and including a controller and a memory for cooperatively;

i. establishing in the memory a virtual node representing each said non-standardized node;

ii. communicating information between each said non-standardized node and the respective virtual node in the communication format/protocol compatible with the respective said non-standardized node;

iii. communicating information between each said virtual node and each said standardized node in a communication format/protocol compatible with said standardized node.

2. A system as claimed in claim 1, wherein said one non-standardized node is a printer.

3. A system as claimed in claim 1, wherein said one non-standardized node is at least one component of a residential entertainment system.

4. A system as claimed in claim 1, wherein said one non-standardized node is a security system.

5. A system as claimed in claim 1, wherein said one non-standardized node is a telephone device.

6. A wireless information system for wireless communication with at least one non-standardized node having a transceiver and being adapted for communication in a communication/protocol compatible with the respective at least one non-standardized node and not adapted for communication with other nodes in acordance with accordance with common standard, said system including:

a. a standardized network including a bus for carrying communications between any standardized nodes that are connected to the bus, said any standardized nodes being adapted for communicating with other nodes in accordance with said common standard;

wherein said standardized node comprises a real half bridge for communicating with other standardized nodes in the standardized network, and

b. a wireless station including a transceiver for wireless communication with the at least one non-standardized node;

c. a virtual network coupled to the wireless station and including a controller and a memory for cooperatively;

i. establishing in the memory a virtual node representing each said non-standardized node;

ii. communicating information between each said non-standardized node and the respective virtual node in the communication format/protocol compatible with the respective said non-standardized node;

iii. communicating information between each said virtual node and each said standardized node in a co cation format/protocol compatible with said standardized node; and

wherein the virtual network includes a virtual half bridge for communicating with the real half bridge, and for communicating with the virtual nodes in the communication format/protocol compatible with the respective non-standardized node.

7. A system as in claim 6, wherein said real half bridge is formed by a bridge interface unit including a physical layer and a link layer.

8. A system as in claim 7, wherein said physical layer is a 1394-Standard physical layer, and said link layer is a 1394-Standard link layer.

9. A system as in claim 6, wherein said virtual half bridge is formed by a virtual intelligence unit comprising said controller, and said memory comprises a program memory and a data memory.

10. A system as in claim 9, wherein said virtual intelligence unit forms a common 1394.1-Standard switching fabric for coupling the two half bridges.

11. A system as claimed in claim 6, wherein said one non-stadardized node is a printer.

12. A method as in claim 11, wherein the step of communicating between each non-standardized node and the respective virtual node comprises communicating by a wireless link.

13. A system as claimed in claim 6, wherein said one non-standardized node is at least one component of a residential entertainment system.

14. A system as claimed in claim 6, wherein said one non-standardized node is a security system.

15. A system as claimed in claim 6, wherein said one non-standardized node is a telephone device.

16. A method of wireless communication in a system including at least one standardized node adapted for communicating with other nodes in accordance with a common standard, and a non-standardized node adapted for communication in a communication/protocol compatible with the non-standardized node and not adapted for communication with other nodes in accordance with said common standard, wherein said non-standardized node lacks computing capability sufficient to communicate in accordance with said common standard, and said method comprises:

a. establishing a viral node representing said non-standardized node;

b. communicating information between said non-standardized node and the virtual node in the communication format/protocol compatible with the respective said non-standardized node, and

c. communicating information between said virtual node and the at least one standardized node in a communication format/protocol compatible with said standarized node.

17. A method as in claim 16, where said at least one said standardized node is part of a standardized network comprising a plurality of said standardized nodes including, and the non-standardized node is one of a plurality of non-standardized nodes, comprising:

establishing a virtual network including a respective virtual node representing each of said plurality of non-standardized nodes,

communicating information between each said non-standardized node and the respective virtual node in accordance with a communication format/protocol compatible with the respective said non-standardized node, and

communicating information between each said virtual node and the associated standardized network in accordance with a communication format/protocol compatible with said common standard.

18. A method of wireless communication in a system including a plurality of standardized nodes adapted for communicating with other nodes in accordance with a common standard, and at least one non-standardized node adapted for communication in a communication/protocol compatible with the respective non-standardized node and not adapted for communication with other nodes in accordance with said common standard, wherein one of said standardized nodes comprises a real half bridge, and said method comprises:
