The initial establishment of a wireless system is very expensive and time consuming process. Due to this it is require to develop a mathematical model before establishment of such type of systems. The calculation of path loss, link budgets etc. are in the part of wireless system designing. Radio propagation is profoundly site specific and varies considerably depending on topography, frequency of operation, speed of mobile terminal, interface sources and other dynamic factor. To predict signal coverage and achieve data rates, it is important to characterize radio channel through key parameters and a mathematical model.
