Abstract:

This study aimed to provide a microwave communications link design connecting PLDT-Brgy. Casmisehos and PLDT-Brgy. Maduya. This design could also be used as a communication link for the companies located in the two sites because PLDT-Brgy Casmisehos, Canlubang, Laguna is now turning into an industrial park and PLDT-Brgy. Maduya is already located inside the People’s Technology Center (PTC).

A descriptive research method was used in the study to determine the factors that could affect the design. These include the path profile, link budget, land elevation, azimuth, and analysis of atmospheric condition that might affect the reliability of the design. In addition, calculations were done based on the gathered data and suggestions of the company. The company recommended using the 6- 7GHz band in the microwave link. On the other hand, the ITU-R recommendation of 7.25-7.55 GHz was used.

The microwave link design had a path length of 12.62 km. The line of sights could be poor if there would be any obstruction higher than the elevation of both sites. These obstructions were only assumed and were based on the topographical map. The computations that were necessary for achieving the target reliability which was 99.999% were made to prove the feasibility of the design.

All the expenses for the design were discussed and computed in the economic study. The study was able to prove that the link design connecting PLDT-Brgy. Casmisehos and PLDT-Brgy. Maduya for data and voice transmission is feasible.
