Abstract:

The study aimed to provide a microwave communication link design connecting Philippine Long Distance Company (PLDT) and Light Industry and Science Park I (LISP I) through Imoc Relay Station, PLDT’s main repeater station located in Calauan, Laguna. The link would serve as PLDT’s secondary connection or back-up in case of failure in their existing fiber optic link.

To comply with the reliability requirement of at least 99.9998%, the study used qualitative method in determining necessary factors that could affect the design. These consist of the path profile, link budget, and azimuth. The calculations were accomplished based on the gathered data and suggestions given by the experts. The selection of radio equipment was based not only on the system requirements but also as recommended by PLDT.

It was proven that the link design was feasible for PLDT’s data and voice transmission. It was also proven that using Siemens Digital Radio equipment best fits the requirements needed by the client-company as it satisfies both reliability and economic analysis. The study, therefore, recommended this microwave communications link design to Philippine Long Distance Company as it was proven reliable after obtaining an overall system reliability of 99.9999%
