Document Type and Number:
WIPO Patent Application WO/2023/096098
Kind Code:
A1
Abstract:
A system for time synchronization between a server and an IoT device according to the present invention comprises: a server for broadcasting a time point synchronization signal including absolute time point information; and an Internet of Things (IoT) device that receives the broadcast time point synchronization signal, and calculates absolute time point information by using the absolute time point information included in the time point synchronization signal, information about the computation time of an internal operation, and information about the transmission time required to receive the time point synchronization signal.
