Cell Coverage Area and Link Budget Calculations in GSM System

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. In This paper we discussed the parameters which are affecting the communication performance and the coverage range of the cell. The coverage starts within the cell, by estimating the affecting parameters on the signal power level in the uplink and downlink at the practical circumstances that means at the mobile station at the cell boundary, or in a high fading region, taking into consideration the factors causing fading and other losses is the signal power.
