Optimum Parameter Analysis of Microwave Link Design in Tripoli

الملخص

The development in communications science is considered one of the most technological developments in the modern era, and microwave wireless communications receives wide attention from communications site designers because of its strong and direct impact on the quality of communications. This development not only led to good performance, but also caused some optimization problems because some standards of several world regions were used jointly without sufficient investigations in sufficiently specific models or regions. In Libya these common standards related to microwave links have not yet been improved, as Libya is calculated according to the classification or division of the countries of the world by the International Telecommunication Union (ITU) with in one region symbolized by the symbol D, which creates or generates some mathematical problems for the rain attenuation, therefor errors in microwave link budget. This research presents how to adjust the design the design parameters of microwave links based on the analysis and actual readings recorded by Al-Madar Al-Jadeed Company on the microwave link in Tripoli as practical example of conducting these analysis. This analysis supported by actual results and within of the specific climate and geographical region, helps predict the performance of microwave links in communications systems and other systems in the future.  In fact, this study can be referred to as a reference for making the necessary changes in the standard values currently in effect in design procedures and taken from (ITU), and thus achieving optimal performance effectively.
