Abstract
In embodiments of distributed channel sampling across a mesh network, a commissioning device propagates a scanning request, which includes a number of scanning parameters, to nodes in a mesh network, causing the nodes to perform energy detection (ED) scans using the scanning parameters. The commissioning device receives energy measurements in scanning reports from the nodes and analyzes the measurements to determine an operating channel for the mesh network. The commissioning device updates the operating channel in network configuration information that is sent to a leader device in the mesh network, for propagation to the mesh network.
