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.

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 FSPL calculator provides the attenuation or loss of a signal as it propagates through free space. In this post we have also provided an example of how to use the calculator. Calculator To calculate the FSPL, enter the following: Frequency of operatio
Introduction SNR, RSSI, EIRP and Free Space Path Loss Signal to Noise Ratio The power level of the RF signal relative to the power level of the noise floor is known as the Signal-to-Noise ratio or SNR. It is the ratio of signal power to the noise
