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. Method for configuration of a first wireless network comprising at least one access point, wherein it comprises a step of configuration of 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 comprising at least two nodes, said nodes being positioned in a determined physical space, said first and second wireless networks being physically different.

2. 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. Method according to claim 1, wherein it comprises a step of determination of said physical space comprising a step of memorisation of 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 network.

4. Method according to claim 3, wherein the step of determination of said physical space also comprises a step of memorisation of an item of information representative of a location of at least one node in the elementary zone comprising it.

5. Method according to claim 1, wherein it comprises a step of reception of the at least a part of the link budget of the second network.

6. Method according to claim 1, wherein it comprises a step of determination of the at least a part of the link budget of the second network.

7. 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. Method according to claim 1, wherein the step of configuration comprises a step of determination of a link budget of the first network according to the link budget of the second network.

9. Method according to claim 1, wherein the link budget of the second 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 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.

10. Method according to claim 1, wherein the second network is a mesh network.

11. Method according to claim 1, wherein the first network uses a first band of frequencies and the second network uses a second band of frequencies different to the first band of frequencies.

12. Method according to claim 11, wherein the difference between the first band of frequencies and the second band of frequencies is less than two octaves.

13. Method according to claim 1, wherein the distribution density of nodes of the second network in said physical space is greater than the distribution density of nodes of the first network in said physical space.

14. Method according to claim 5, wherein it comprises a step of request to obtain the at least a part of the link budget of the second network.
