Performance Evaluation of Microwave Link: Comparative Case

Purpose: To investigate the impact of climatic and environmental variations on microwave link performance, with a focus on evaluating the accuracy of rain attenuation models provided by the International Telecommunication Union (ITU) compared to real-world measurements.

Materials and Methods: This study conducts a comparative analysis between theoretically calculated rain attenuation based on ITU standards and actual measured data obtained from microwave link records of Al-Madar Company in Benghazi. The methodology relies on analyzing real operational data within a specific geographical and climatic context to assess discrepancies and performance implications.

Results: The findings reveal noticeable differences between ITU-based calculations and measured attenuation values, indicating that applying generalized international standards without local adaptation may lead to inaccuracies in microwave link budget estimations and overall system performance.

Conclusion: The study highlights the necessity of incorporating region-specific climatic data into microwave link design. It demonstrates that adjusting ITU standard values based on local measurements can significantly improve the accuracy and reliability of communication system performance predictions, making this approach valuable for future network planning and optimization.
