Whenever new cellular technology is considered for mass deployment hundreds of its RF parameters go through tuning process with a view to find out optimum value. And usually, it costs a lot of time and money. Consequently, extensive simulation becomes meaningful before commercial deployment. System can be facilitated in numerous ways and cost would be greatly minimized. With the path loss and propagation model, the radius of the site, the sites spacing and the coverage area of the site can be calculated. The system characteristics of LTE FDD and the link budgets for LTE FDD and WCDMA are calculated in this paper.
