Problems solved by technology

This often also leads to system limitations, since interference from other transmission nodes in the mesh network or such as from other transmission nodes in other mesh networks often results in higher and higher bit error rates when data packets are transmitted

Abstract

Disclosed is a station of a mesh network, wherein the station is configured to transmit and receive data packets comprising a header which comprises a mesh mode channel switch announcement element anda mesh channel switch parameter element. The station also comprises: a controller, which is configured to initiate communication with at least one second station on a first communication channel; a transceiver, which is configured to transmit and receive data packets to and from the at least one second station on the first communication channel; a counter, which is configured to monitor an amountof lost data packets. If the amount of lost data packets exceeds a drop threshold, the controller is further configured to determine if at least one communication criterion is fulfilled. If the controller determines that the at least one communication criterion is fulfilled, then the controller is configured to move the communication from the first communication channel to a second communicationchannel during the remainder of the communication. The movement of the communication from the first communication channel to the second communication channel is unrestricted in time or time scheduled.A method for a mesh station as well as a computer program product is also disclosed.

Description

technical field [0001] The present invention relates generally to the field of mesh networks. More specifically, the present invention relates to interference-free communications in mesh networks. Background technique [0002] A mesh network consists of nodes (also denoted stations in this disclosure) that are typically connected to neighbors within the radio link range of the node (ie how far its communication signals can travel). The range of a radio link is usually determined by parameters such as the output power and sensitivity of the radio transceiver used for communication. However, in large dense mesh networks, several nodes may be within range of the same radio link. This often results in limited connectivity and capacity in mesh networks due to interference between nodes. [0003] Another challenge of mesh networks is generally to ensure that nodes are heard by enough neighbors (also denoted peers in this disclosure) that all nodes can connect directly or via mu...
