Abstract

The invention relates to method for configuring a first wireless network that includes at least one access point. In order to optimize the configuration of the first wireless network, the method comprises a step of configuring at least one parameter of the at least one access point of the first wireless network on the basis of at least a portion of the linking balance of a second wireless network including at least two nodes, the nodes being positioned in a predetermined physical space.

Claims

1. A method for configuration of a first wireless network including at least one access point, the method comprising:

configuring, by a computer processor, at least one parameter of said at least one access point of the first wireless network according to at least a part of a link budget of a second wireless network including at least two nodes, said nodes being positioned in a determined physical space, said first and second wireless networks being physically different, said first wireless network using a protocol based on IEEE 802.11 and said second wireless network using a protocol not based on IEEE 802.11,

wherein the configuring comprises determining a link budget of the first wireless network according to the link budget of the second wireless network,

wherein the link budget of the second wireless network is according to measurements of received power of a signal transmitted by at least one node and received by at least one other node of the second wireless network, said measurements being carried out for at least two different transmission channel frequencies of said signal, said at least two transmission channel frequencies belonging to a same frequency band.

2. The method according to claim 1, wherein the first wireless network uses a first physical channel and the second wireless network uses a second physical channel, the first and second physical channels being different.

3. The method according to claim 1, wherein the method comprises determining said physical space, said determining comprising memorizing an item of information representative of elementary zones comprised in the physical space, said elementary zones each comprising at least one node of the second wireless network.

4. The method according to claim 3, wherein determining said physical space also comprises memorizing an item of information representative of a location of at least one node in the elementary zone comprising the at least one node.

5. The method according to claim 1, wherein the method comprises receiving the at least a part of the link budget of the second wireless network.

6. The method according to claim 1, wherein the method comprises determining the at least a part of the link budget of the second wireless network.

7. The method according to claim 1, wherein said parameter is selected from among:

at least one spatial parameter,

at least one physical layer parameter,

at least one parameter of a layer above the physical layer,

or any combination of these parameters.

8. The method according to claim 1, wherein the second wireless network is a mesh network.

9. The method according to claim 1, wherein the first wireless network uses a first band of frequencies and the second wireless network uses a second band of frequencies different to the first band of frequencies.

10. The method according to claim 9, wherein the difference between the first band of frequencies and the second band of frequencies is less than two octaves.

11. The method according to claim 1, wherein the distribution density of nodes of the second wireless network in said physical space is greater than the distribution density of nodes of the first wireless network in said physical space.

12. The method according to claim 5, wherein the method comprises requesting to obtain the at least a part of the link budget of the second wireless network.

13. A device configured for configuring a first wireless network including at least one access point, the device comprising:

a processor configured to compute at least one parameter of said at least one access point of the first wireless network according to at least a part of a link budget of a second wireless network including at least two nodes, said nodes being positioned in a determined physical space, said first and second wireless networks being physically different, said first wireless network using a protocol based on IEEE 802.11 and said second wireless network using a protocol not based on IEEE 802.11,

wherein the processor is further configured to determine a link budget of the first wireless network according to the link budget of the second wireless network,

wherein the link budget of the second wireless network is according to measurements of received power of a signal transmitted by at least one node and received by at least one other node of the second wireless network, said measurements being carried out for at least two different transmission channel frequencies of said signal, said at least two transmission channel frequencies belonging to a same frequency band.

14. The device according to claim 13, wherein the first wireless network uses a first physical channel and the second wireless network uses a second physical channel, the first and second physical channels being different.

15. The device according to claim 13, further comprising:

a memory device configured to memorize information representative of elementary zones comprised in the physical space, said elementary zones each comprising at least one node of the second wireless network, said processor being further configured to determine said physical space from the memorized information.
