毫米波通信是一种非常有前途的技术，可以为下一代无线局域网（wlan）提供每秒千兆比特的传输速率。为了在室内场景中实现这种超高吞吐量性能，视线（LoS）连接成为一项关键要求。先前的工作已经提出将接入点（AP）移动性作为改善LoS条件的方法，从而实现最佳毫米波WLAN性能。在这项工作中，我们对线性AP迁移进行了全面的模拟研究，研究了各种维度，包括移动AP的数量、移动AP平台的位置和平台的长度。结果显示了WLAN性能在这些维度上的变化，并将结果与不同数量的静态ap进行比较，以量化从移动性中获得的性能增益。结果表明，即使是2或3个移动ap也可以显著优于大量的静态ap，并且在一个房间中部署多达3个移动ap可以带来可观的性能提升。
Millimeter-wave communication is a highly promising technology to deliver multi-gigabit-per-second transmission rates for next-generation wireless LANs (WLANs). To achieve such ultra-high throughput performance in indoor scenarios, line-of-sight (LoS) connectivity becomes a critical requirement. Prior work has proposed access point (AP) mobility as an approach to improve LoS conditions and, thereby, approach optimum mmWave WLAN performance. In this work, we present a comprehensive simulation study of linear AP mobility that investigates various dimensions, including the number of mobile APs, the placement of the mobile AP platforms, and the length of the platforms. The results show how WLAN performance varies across these dimensions and also compares the results against a varying number of static APs to quantity the performance gains achievable from mobility. The results show that even 2 or 3 mobile APs can significantly outperform a much larger number of static APs and that deploying up to 3 mobile APs in a room brings substantial performance gains.
