Management of Radio Frequencies in a Wireless or Hybrid Mesh Network
First Claim
1. A communication node for use in a wireless or hybrid mesh communication system, having a first radio interface used for uplink communication over a first frequency channel, and at least one second radio interface, each second radio interface being used for downlink communication with at least one child node over a second frequency channel, the communication node and the at least one child node defining a family, comprising:
- first modules adapted to store a set of spare frequency channels for the family,second modules adapted to change and have the at least one child node change the second frequency channel to a third frequency channel, andthird modules adapted to select the third frequency channel from the set of spare frequency channels if the set of spare frequency channels is not empty, to request and obtain the third frequency channel) through the first radio interface from a root node of the communication system if the set of spare frequency channels is empty.

Abstract
In a wireless or hybrid mesh communication system, radio frequencies are managed by assigning an in-use frequency channel to each local family of nodes, distributing spare frequency channel(s) among the local families of nodes, and changing the in-use frequency channel of at least one selected local family of nodes to a new frequency channel selected among its spare frequency channel(s), if any, or among the spare frequency channel(s) of another local family of nodes if said at least one selected local family of nodes has no spare frequency channel(s), and/or as the in-use frequency channel of another local family of nodes if none of said local families of nodes has spare frequency channel(s).

6. A communication node for use in a wireless or hybrid mesh communication system, the communication system comprising at least one family formed of a parent node and at least one child node communicating over a frequency channel, comprising:
-
first modules adapted to assign a set of spare frequency channel to each of the at least one family, and second modules adapted to receive a request for a new frequency channel from a parent node of the at least one family, the request being sent by the parent node when its set of spare frequency channels is empty, and to provide the new frequency channel to the parent node. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A method of managing radio frequencies within a wireless or hybrid mesh communication system, comprising the steps of:
-
assigning an in-use frequency channel to each local family of nodes, distributing spare frequency channels among the local families of nodes, changing the in-use frequency channel of at least one selected local family of nodes to a new frequency channel selected among its spare frequency channels, if any, or among the spare frequency channels of another local family of nodes if the at least one selected local family of nodes has no spare frequency channels. - View Dependent Claims (18)
