Abstract:
Microwaves are widely used for point to point
communications, because their small wavelength allows
conveniently-sized antennas to direct them in narrow beams,
which can be pointed directly at the receiving antenna. This
allows nearby microwave equipment to use the same
frequencies without interfering with each other.
The aim of the thesis was to provide microwave radio link
operating at microwave frequencies Jimma main and Agaro
campuses, with the minimum objective reliability 99.999%.
The designed link depends on Geo context-profiler for path
profile analysis, Feko suite 5.5 for rectangular waveguide
design, and link budget calculator. In the analysis there are
parameters, which are significant in design of microwave link
establishment: free space loss calculation, path profile
analysis, fade margin, frequency planning, attenuation, rain
fading predictions, reflection points calculation, , tower
heights, Signal to Noise Ratio, Fresnel zone and link budget
calculation. Fresnel zone clearance was considered at least at
60% of the first Fresnel zone
