调查是否增强的访问点 (AP) 功能,特别是多用户MIMO (MU-MIMO),可以支持密集的VR部署.
识别限制在VR环境中Wi-Fi性能扩展的瓶.

主要方法:

开发了一个高保真模拟框架,使用ns-3来估计VR流量的网络容量.
评估了AP和STA天线数量,MU-MIMO调度,频道发声时间和频道条件的影响.
分析了性能扩展,增加了AP天线数量.

主要成果:

在多用户VR场景中,Wi-Fi性能可扩展性不是线性的.
在典型条件下,将AP天线从8倍增加到16倍只能增加35%的容量.
确定了防止无限期性能扩展的关键瓶,使用更多的AP天线.

结论:

仅仅增加AP天线,即使使用MU-MIMO,也不足以支持密集的VR部署.
了解和解决已识别的瓶对于为Metaverse和沉浸式VR设计下一代Wi-Fi系统至关重要.
这项研究为优化 Wi-Fi 网络设计,为未来的 VR 应用提供了关键的见解.

Energy Stored In A Coaxial Cable

Energy Stored In A Coaxial Cable

A coaxial cable consists of a central copper conductor used for transmitting signals, followed by an insulator shield, a metallic braided mesh that prevents signal interference, and a plastic layer that encases the entire assembly.
In the simplest form, a coaxial cable can be represented by two long hollow concentric cylinders in which the current flows in opposite directions. The magnetic field inside and outside the coaxial cable is determined by using Ampère's law. The magnetic field inside...

Propagation Speed of Electromagnetic Waves

Electromagnetic waves are consistent with Ampere's law. Assuming there is no conduction current Ampere's law is given as:

Maximum Power Transfer

Maximum Power Transfer

Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.
By substituting the entire circuit with...
