Description: This study mainly aimed to: investigate different settings and parameters that should be done in each technology, conduct different simulations in different scenarios similar to practical environment and scenarios, find the best options that can be used to achieve the optimum performance level of the network in each technology, draw a general guideline for future works based on realistic simulation results, clarify the pros and cons of deploying each technology which can be helpful for telecom companies to review their options and decisions. The methodology of the study depended on discussing the specifications of each technology, then it presented the citied requirements and parameters of each technology, then it presented the initial settings and results, and finally it presented the steps of optimization process. The study presented results that were gotten after the optimization process, and it compared it with the results that were gotten before the optimization process. Each result was discussed in term of cause and effect style. The study has come up with many findings. The most important findings state that; deploying 5G NR networks requires a cost and an effort that is much higher than the required cost and effort of deploying LTE networks, and this is a result of many factors and parameters that are different in 5G NR, deploying 5G NR networks requires a larger number of cells that cover areas that are smaller than these used in LTE, deploying 5G NR networks requires paying a higher level of attention to the terrains of the area and the obstacles within the area, and this is because the small wavelength that is used in 5G which does not a good ability of penetration through obstacles, transmitters in 5G perform better when they are mounted on towers with a lower height than the height used in LTE. The study has came up with many recommendations. The most important recommendations state that; transmitters must be mounted on a height of 40m in the case of LT
