MUMBAI, India, Nov. 7 -- Intellectual Property India has published a patent application (202514017961 A) filed by Xiamen Lanxu Intelligent Technology Co. Ltd., Fujian, China, on Feb. 28, for 'communication method, medium, module, photovoltaic cleaning device and networking system.'
Inventor(s) include Jingci Li; and Lijun Huang.
The application for the patent was published on Nov. 7, under issue no. 45/2025.
According to the abstract released by the Intellectual Property India: "The present invention discloses a communication method, a medium, a module, a photovoltaic cleaning device and networking system. The method includes: S1: dividing a plurality of frequency point information in the frequency band used by a node device to report data to obtain a plurality of frequency point sets; where each node device corresponds to a frequency point set, each frequency point set includes at least one frequency point information, and frequency point information contained in different frequency point sets is different; S2: when the node device accesses a gateway, randomly selecting one frequency point information from the frequency point set corresponding to the node device as the frequency point information corresponding to the current node device; S3: reporting relevant data of the current node device through the selected frequency point information at the preset period. Through the above solution, since different node devices can share the same frequency band but use different frequency points in the same frequency band, uplink data does not interfere with each other, and the multiplexing of the gateway is improved."
