Abstract

A dual mode, dual band wireless communication network (100) and a method for using the same. The wireless communication network (100) includes nodes, such as mobile nodes (102), access points (106) and wireless routers (107), that can communicate wirelessly over two different frequencies, for example, 2.4 GHz and 4.9 GHz, to provide high mobility and high data rate capabilities, and for communication with 802.11 compliant and non-802.11 compliant devices.

Claims

1. A node for communicating in a wireless communication network, the node comprising:

a first communication device comprising first and second transceivers, each adapted to communicate wirelessly over a first frequency; and

a second communication device comprising third and fourth transceivers, each adapted to communicate wirelessly over a second frequency.

2. A node as claimed in claim 1, wherein:

the first frequency is at the 2.4 gigahertz (GHz) range and the second frequency is at the 4.9 GHz range.

3. A node as claimed in claim 1, wherein:

at least one of the first and third transceivers is adapted to communicate with a network other than the wireless communication network.

4. A node as claimed in claim 1, wherein:

at least one of the first and second transceivers, and at least one of the third and fourth transceivers, are adapted to wirelessly communicate with at least one other node that communicates in accordance with IEEE Standard 802.11.

5. A node as claimed in claim 1, wherein:

at least one of the first and second transceivers, and at least one of the third and fourth transceivers, are adapted to wirelessly communicate with at least one other node whose communication does not comply with IEEE Standard 802.11.

6. A node as claimed in claim 1, wherein:

the third and fourth transceivers are adapted to communicate wirelessly over different channels within a range of the second frequency.

7. A node as claimed in claim 1, wherein:

wherein at least one of the first and second communication devices is adapted to route packets between other nodes in the wireless communication.

8. A method for communicating in a wireless communication network, the method comprising:

providing a node comprising a first communication device comprising first and second transceivers, and a second communication device comprising third and fourth transceivers;

operating the first and second transceivers to communicate wirelessly over a first frequency; and

operating the third and fourth transceivers to communicate wirelessly over a second frequency.

9. A method as claimed in claim 8, wherein:

the first frequency is at the 2.4 gigahertz (GHz) range and the second frequency is at the 4.9 GHz range.

10. A method as claimed in claim 8, further comprising:

operating at least one of the first and third transceivers to communicate with a network other than the wireless communication network.

11. A method as claimed in claim 8, further comprising:

operating at least one of the first and second transceivers, and at least one of the third and fourth transceivers, to wirelessly communicate with at least one other node that communicates in accordance with IEEE Standard 802.11.

12. A method as claimed in claim 8, further comprising:

operating at least one of the first and second transceivers, and at least one of the third and fourth transceivers, to wirelessly communicate with at least one other node whose communication does not comply with IEEE Standard 802.11.

13. A method as claimed in claim 8, wherein:

the step of operating the third and fourth transceivers comprises operating the third and fourth transceivers to communicate wirelessly over different channels within a range of the second frequency.

14. A method as claimed in claim 8, further comprising:

operating at least one of the first and second communication devices to route packets between other nodes in the wireless communication.

15. A wireless communication network, comprising:

at least one first node comprising first and second communication devices, the first communication device comprising first and second transceivers, each adapted to communicate wirelessly over a first frequency, and the second communication device comprising third and fourth transceivers, each adapted to communicate wirelessly over a second frequency; and

at least one second node, the first and second nodes being adapted to communicate with each other.

16. A wireless communication network as claimed in claim 15, wherein:

the first frequency is at the 2.4 gigahertz (GHz) range and the second frequency is at the 4.9 GHz range.

17. A wireless communication network as claimed in claim 15, wherein:

the first node is further adapted to communicate with a network other than the wireless communication network.

18. A wireless communication network as claimed in claim 15, wherein:

the first node is adapted to communicate with a said second node that is adapted to communicate in accordance with IEEE Standard 802.11 and with another said second node that is adapted to communicate in a manner that does not comply with IEEE Standard 802.11.

19. A wireless communication network as claimed in claim 15, wherein:

the first node is adapted to route packets between the second nodes in the wireless communication.

20. A wireless communication network as claimed in claim 15, wherein:

the first node is adapted to route packets between the second node and a network different than the wireless communication network.
