Tropospheric influence on dropped calls in mobile networks

It is common knowledge that tropospheric variables affect signals, thereby distorting coverage. Since the major factor affecting dropped calls coverage and penetration depth of signal strength transmitted by a wireless system determines its coverage, therefore, there tendency for to calls. This research investigates effects relative humidity, wind speed, rainfall temperature on four mobile networks (MTN, Airtel, Globacom 9mobile) in Cross River State, Nigeria. Six years data weather collected from Nigerian Meteorological Agency (NiMet), State six Drop Call Rate (DCR) obtained telecommunications regulatory body, Communication Commission (NCC), was used this study, both spanning January 2015 December 2020. From data, graphs were plotted and, each case, DCR dependent while independent variables. Also, regression models forecast network, provided variable at given period known. Finally, correlated give picture how related networks. For MTN 9mobile networks, low positive correlation highly speed lowly negative temperature. Airtel moderately exists between humidity/temperature relationship existed rainfall. However, observed speed. humidity respectively temperature/wind against DCR. result will be very useful meteorologist, network planners operators.
