Microwave Link Design Between Two Business Locations: Case Study of Irrua Specialist Teaching Hospital and Ambrose Alli University Main Campus, Ekpoma
This paper presents the design of microwave link between two business locations. The objective was to analyze a point-to-point microwave link between Irrua Specialist Teaching Hospital and Ambrose Alli University. The Saf-Path Calculator was used in this study, the design is limited to the Saf-Path Calculator for antenna feed design. The path round walk was conducted to verify the line-of-sight clearance, reflective potential surfaces; such as flat terrain, and water bodies and manmade obstructions. The planning of the link took into account cost, equipment availability frequency planning; link budget, rain fading, fade margins, outages and availability calculations. Differences were observed in the fade margin at antenna height (40, 50, 60, 70, and 75 m). Between 40 and 50 m, the signal quality is the same and the fade margin is different. Antenna heights 40 and 60 m have similar fade margin and different signal quality while that of 50 and 70 m have different fade margin and signal quality and antenna height 70 and 75 m have different signal quality and different fade margin.
