Title:
METHOD FOR CHANNEL SWITCHING IN WIRELESS MESH NETWORK, AND WIRELESS DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/136062
Kind Code:
A1
Abstract:
Disclosed is a method for channel switching in a wireless mesh network. The method comprises: any slave node in a wireless mesh network receiving a channel switching command broadcast by a master node to perform channel switching; the slave node determining whether the channel switching is successful; and if successful, searching for the master node or a network containing the master node for networking; otherwise, exiting the current invalid mesh network, and scanning for a mesh network after the channel switching, and joining the detected mesh network. According to the present application, after channel switching is performed, a mesh network of a slave node is automatically configured, thereby making up for the defect of an existing mesh network protocol not supporting switching between different frequency bands, and realizing automatic re-establishment of a mesh connection after the channel switching is successful.
