ANALYSIS ON PREDICTION OF PATH LOSS FOR MOBILE NETWORK IN JNEC, DEWATHANG AT 1800 MHz

Abstract

As the mobile cellular subscription is constantly increasing, the demand for good network and data traffic, remains to be high. In order to achieve that, proper network planning is important to enhance reliable mobile network and optimization. Path loss modelling is extensively used in the initial feasibility studies for the proper deployment of telecommunication. Prediction of path loss helps to indicates the field strength of the radio propagation. Path loss is the weakening of signal strength during propagation and can be determined by using different models. Largely affected by the complex terrain, buildings, trees, generally, the path loss is caused by reflection, refraction and diffraction. The evaluation is performed at 1800 MHz frequency which is the operating band of Long-Term Evolution (LTE) 4G network service in the region. A comparative study is done between different types of path loss models used in LTE networks in MATLAB. Analysis of path loss for irregular terrain in the region is also being simulated using Radio-mobile. With this study, a person can predict the mobile signal quality and a proper network can be planned.
