Abstract: Based on the current lack of accurate test methods for wireless end-to-end delay, this paper proposes a wireless communication one-way delay test scheme for the sender or receiver. Aiming at the internal clock timing, a key factor affecting the delay test results, a clock linear compensation strategy is proposed to achieve linear compensation within seconds and a multi-source high-frequency clock correction strategy to achieve CPU high-frequency clock replacement. According to the test scheme, the test terminal is developed based on the four-layer structure, and the test verification of one-way delay and jitter value of wireless network is completed in the demonstration area.
