The designed project was intended to give Philippine Long Distance Telephone Company (PLDT) a reliable fixed microwave link design from Crossing, Calamba to Nuvali, Sta. Rosa, Laguna. The study would provide link from PLDT Crossing, Calamba, to Nuvali, Sta. Rosa, with the use of microwave for the implementation of Enhanced Data Rate for GSM Evolution. The link is designed to have a reliability of 99.9998% in view of all the probable attenuations.


The study meant to create a microwave link design that includes the requirements of a reliable taking into account the requirements given by the National Telecommunications Commissions and other standards in relation to microwave propagation. Descriptive type of research was used in this study in order to describe the specification of a reliable microwave.


The design consists of a single hop microwave design with a PL4-65-P7A/F, 1.2 meter antenna, vertically polarized, 6.425-7.11 GHz, gray antenna; EWP63S super premium elliptical waveguide, and the Harris Truepoint 6500 microwave radio.


Economic study was conducted to determine the cost effectiveness of the system. The estimated total investment cost is Php. 9,541,317.44 with a Php. 59,429,444.44 as the project’s annual income. The total outlay has a rate of return of 309.599% which can be acquired after four months and three days of function.
