Feasibility Study

To design a microwave system for optimum performance, you need to complete:

• a reliability analysis
• line-of-sight (LOS) analysis
• centerline optimization calculation

A reliability analysis determines the predicted outage time per year, and the corresponding percentage of reliability for a given path. These are critical factors that will determine the successful operation of your path.

The line-of-sight (LOS) analysis determines whether the path clears a user-defined percentage of the first Fresnel zone and is therefore usable. The LOS analysis may be performed during the site selection process or during this feasibility step.

The centerline optimization(CL) calculation is an extension of the LOS analysis. It provides the minimum antenna centerline heights needed to ensure LOS clearance of a user-defined percentage of the first Fresnel zone.

There are several options available for these analyses.

• Comsearch can perform these services for you. Request a quote for a reliability analysis.
• To perform the LOS/CL optimization yourself, you need the ground elevations or path profile between two points.
• You can also utilize a software tool to conduct the analyses. Learn more about Comsearch's path design software product, iQ·link^®.
