中文摘要：

针对无线局域网测试的信道采样问题，提出了一种新的采样策略：带最小时间的PTF采样策略。通过仿真与分析，说明了现有策略的不足，新策略可以满足不同应用的需求；结果表明带最小时间的PTF采样策略能够胜任所有状况的无线网络信道采样。

英文摘要：

Aimed at the question of channel sampling in wireless LAN test, a new sampling strategy： PTF sampling with minimum time is introduced. Through simulation and analysis, the result illustrates the inadequacy of current strategies. The new strategy can meet different application requirements. It is shown that the strategy of PTF sampling with minimum time is competent enough to all states of the wireless networking channel sampling.
