An ultra low power wireless node () sends () a packet on at least two radio channels to a network of backbone nodes (). Which of the radio channels are listened for at the backbone nodes is allocated () according to detected reception performance. The allocating is coordinated for different ones of the backbone nodes. By combining sending on multiple radio channels with dynamically allocating the listening channels according to reception performance and with coordinated allocations for different backbone nodes, the spatial diversity and channel diversity of the separate receiving locations can be exploited. This can make the system more resilient to time varying location specific interference or channel specific interference for example.

Radio channel allocation for wireless interface using ultra low power nodes

A wireless system () comprises an initiator device () and a plurality of responder devices (-) which can bind with the initiator device (). The method comprises, at one of the plurality of responder devices, receiving () a discovery request from the initiator device and forming a discovery response and sending the discovery response to the initiator device. The step of forming a discovery response comprises: collecting () at least two parameters indicative of the initiator device wanting to bind with the responder device; computing () a score using the at least two parameters, the score being indicative of a likelihood of the initiator device wanting to bind with the responder device; and including () the score as an element of the discovery response.
