Research and Design of Wireless Network Time Synchronization Module Based on IEEE1588 Protocol

Abstract

Wireless network systems have many problems, such as low data transmission rates, limited coverage, limited measurement node capacity, and low time synchronization accuracy, especially the millisecond-level time synchronization accuracy can no longer meet the needs of the market.Therefore, it is urgent to find a more accurate time synchronization technology solution. At the same time, the accuracy of the time synchronization of the IEEE1588 protocol in a distributed wired network can reach the nanosecond level, so it is extremely important to introduce it into a wireless network to achieve more accurate time synchronization in the wireless network. This paper is the research and design of high-precision time synchronization module for wireless network based on IEEE1588 protocol. It mainly uses ARM + FPGA + WLAN structure to design time synchronization module. According to the actual test of the module, it can be known that the time synchronization accuracy that the wireless network time synchronization mode can achieve is as high as 150ns, which can fully meet the needs of the wireless market for time synchronization accuracy.
