Before a microwave link can be installed, an analysis and calculation of the microwave link must be made first. The analysis should take place before the site survey itself to get a clear idea about the dimensions of the antennas. The analysis consists of the following steps:
Free space loss calculation
Link budget calculation
Rain attenuation
Multipath fading
Fade margin
Fresnel zones calculation
This chapter explains the individual steps and an example of link design is given at the end.
