Abstract:
This study conducted a design simulation for a microwave radio link for the extension of the bandwidth from the Point-of-Presence facility. The microwave radio link design was simulated using the Pathloss tool and the modulation technique of 128 QAM modulation. Different antenna dimensions of 1.8m, 1.2m, and 0.6m were used in order to perform design simulations to correlate stated variables that are characterized for the microwave link. Based on the design simulations, Design Simulation 3 with the smallest antenna dimension of 0.6m resulted in a minimal link unavailability of 0.08 minutes and had the highest link availability of 99.99998%, which translates to a reliable radio link that is within the reference of the acceptable range of values for link availability. As the dimensions of the antenna were changed, there was a significant change in the link unavailability time. Small diameter antennas are favorable to use, when possible, because of their small aperture for wind and tower, which results in considerably less tower leasing costs.
