Performance Evaluation of 4G Mobile Wireless Network in Nigeria

The Fourth Generation (4G) of mobile wireless networks introduced significant improvements in terms of speed, reliability, and capacity compared to its predecessors. This study presents a comprehensive performance evaluation of 4G Long-Term Evolution (LTE) networks in urban environments using Free Space Path Loss Model and COST 231 Hata Model. Metrics such as pathloss, signal power and signal-to-noise ratio were determined through simulation. The results show that while 4G networks meet basic broadband requirements, performance varies significantly depending on factors like frequency, location and so on. The results also show that, out of the three selected mobile networks in Nigeria, Globacomm performs better than MTN and Airtel by 1.9% and 3.5% respectively with the application of Free space path loss model, and by 7.8% and 14.8% on application of COST 231 Hata model.
