5G MMWAVE技术承诺能力为4G的10至100倍。但是，MMWave链接对发件人和接收器之间的直接视线非常敏感，由于短暂的阻塞和阴影褪色，其容量急剧波动，这可能会大大降低TCP的性能。 TCP切片代理（SPEP）通常用于改善无线链接的TCP性能。我们使用Monroe1测试台研究了当前的操作员SPEP（用于4G LTE网络）。我们为城市峡谷场景介绍了MMWave仿真模型，并使用它来评估当前的操作SPEP如何影响性能。我们来自包括四个运营商和三个国家在内的实验的结果表明，对于5G mmwave而言，SPEP比在LTE中更为重要。当前的4G SPEP在类似于MMWave的条件下提供了显着的（尽管不是最佳），从而使它们被用作网络过渡到5G技术。
5G mmWave technology promises capacities 10 to 100 times that of 4G. However, mmWave links are very sensitive to having direct line of sight between sender and receiver, with dramatically fluctuating capacities due to transient blocking and shadow fading, which can substantially degrade TCP performance. TCP-splitting proxies (SPEPs) are often used to improve TCP performance over wireless links. We investigate current operator SPEPs (used in 4G LTE networks) under mmWave-like dynamics using the MONROE1 testbed. We introduce a mmWave emulation model for an urban canyon scenario, and use it to evaluate how current operational SPEPs impact the performance. Our results from experiments including four operators and three countries, indicate that SPEPs will be even more important for 5G mmWave than they are in LTE. Current 4G SPEPs provide significant, though not optimal, benefits under mmWave-like conditions, allowing them to be utilized as the network transitions to 5G technology.
