This paper details the simulative analysis of a high-speed microwave point-to-point link boasting a data rate of 474.62 Mbit/s over a distance of 47 km. The paper considers University of Port Harcourt (UNIPORT) as Site A and Rivers State University (UST) as Site B. The aim was to devise a robust communication system to facilitate seamless communication network between these two university campuses. The design process involved meticulous consideration of factors such as antenna selection, modulation scheme, and link budget analysis. These considerations were tailored to suit the geographical and environmental characteristics of the chosen sites. Radio link planner simulation tool played a pivotal role in evaluating the system’s performance across various scenarios, taking into account terrain obstacles and weather conditions. The results conclusively demonstrate the feasibility of establishing a reliable microwave point-to-point link between UNIPORT and Rivers State University. The study includes calculations of Signal-to-Noise ratio (SNR) of 1.09 × 10-4dB, percentage reliability of 99.9999964% and an assessment of the Bit Error Rate (BER) graph to gauge signal quality effectively. These findings underscore the system’s capability for high-speed data transmission, thereby fostering improved connectivity and collaboration between both of the academic institutions.
