无线网络可用带宽测试技术方案研究

摘要

With the advent time of LTE age, faster data transmission rate was provided. However, the disadvantage of traditional FTP testing method such as over-consumption of data traffic and impact on user makes it insufficient to fulfil the current testing need. It indicates a method based on impulse sample technology. Compared to FTP testing method, the method has the ad-vantage of a smal consumption of data traffic, less impact on network, higher sampling precision and less affected by testing equipment with the similar testing result which has been verified by comparison test.%随着LTE时代的到来，无线网络提供了越来越高的数据传输速率，但是传统的FTP速率测试方法存在流量消耗大、对现网用户影响大等缺陷，已越发不能适应当前测试工作的需要。详细阐述了一种基于脉冲采样技术的可用带宽测试技术方案，在与FTP测试结果基本接近的前提下具备流量消耗小、现网侵扰度低、采样精度高、受设备影响小等优势，并通过实际测试数据进行了对比验证。
