THE COMPARATIVE ANALYSIS OF WEIBULL AND RAYLEIGH DISTRIBUTIONS UNDER STOCHASTIC APPROACH IN 4G AND 3G CELLULAR NETWORK

The aim of this paper is to investigate and compare the stochastic parameters of the received signal in a cellular network between UMTS (3G) and LTE(4G). Drive test measurements are conducted on a street having the high rise building on both sides wherein the line of sight from the cell tower to mobile devices is not clear. Therefore, the street (120 meters long) between block-7 and block-8 (Lat: 8.3162452/8.3162767; Long: 35.559375/35.5597058) in the Mattu University (Ethiopia) has been chosen for this. Insinix hot.9 smartphones with an “Android 7+” operating system and “cell info” software were used during the observations and measurements in Ethio-telecom coverage. Collected received signal strength is used to plot the Weibull [1] and Rayleigh [2] distribution with help of Easy Fit software. Consequently, the statistical data of the random variable (received signal strength) in a stochastic behaviour like mean, variance standard deviation, coefficient of variation, and skewness will be calculated and compared.
