序言 在无线局域网中,主要的性能除了吞吐量之外,另外一项比较受人关注的就是覆盖范围,而为了计算Wi-Fi的覆盖范围,我们首先要梳理其链路模型。本文我们基于基本的自由空间传输损耗模型(Free-space path loss),对802.11中的链路模型进行分析。 注:在该文之后,我们会基于在理解链路模型的基础上,继续讨论如何计算无线的...

The free-space path loss,L, in decibels is: L = 20log10(4πR/λ). This formula assumes that the target is in the far-field of the transmitting element or array. In the near-field, the free-space path loss formula is not valid and can result in a loss smaller than 0 dB, equiva...

Free-space path loss (FSPL) describes the attenuation of signal strength that occurs as an electromagnetic wave travels through open air or a vacuum.
The free space path loss is used to predict the strength of a RF signal at a particular distance. This is a theoretical value, as in the real world, there are many obstacles, reflections and losses which need to be accounted for when estimating the signal at a location. However the FSPL...

The free space path loss in decibels is approximately 197.5 dB. Alternatively, you can compute the loss directly from Loss = 2*pow2db((4*pi*tgtrng/lambda)^2) Loss = 197.4635 Propagate Linear FM Pulse Waveform to Target and Back
将“free space path loss"翻译成西班牙文 FSL, atenuación en el espacio libre, atenuación en espacio libre是“free space path loss"到 西班牙文 的最佳翻译。 译文示例:With the above two Free Space Path Loss equations, we can find out the Distance in km. ↔ Con las dos ecuaciones de...
