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覆盖范...

Free-space path loss describes the attenuation of signal strength that occurs as an electromagnetic wave travels through open air or a vacuum. Free space path loss is fundamental in wireless communications and radio frequency engineering applications. While free-space path loss primarily affects wireless...
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 in dB Assume a transmitter is located at(1000,250,10)in the global coordinate system. Assume a target is located at(3000,750,20). The transmitter operates at 1 GHz. Determine the free space path loss in decibels for a narrowband signal propagating to and from the ta...
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...
