Abstract
The present disclosure provides a communication method of an electronic shelf label system, a system, a computer device and a storage medium. The method includes: configuring, by a server, an offset of each of base stations in a corresponding synchronization sub-network based on neighboring relationships between all the base stations in each of the synchronization sub-networks, so that each of the base stations calculates synchronization frame transmission time in a predetermined signal transmission cycle based on the offset; calculating, by each of the base stations, idle time in a synchronization channel based on the synchronization frame transmission time, so that each of the base stations receives a target synchronization frame sent by a superior base station in the idle time of the synchronization channel. According to the present disclosure, the synchronization frames sent by all the base stations has central and adjacent feature in time.
