Wireless communication services have been growing at a rapid pace in recent years. As the number of mobile communication users’ increase, the demand for a more reliable mobile network also increases. Therefore, there is an important need for overall improvement in mobile network performance using Multiple In-Multiple Out (MIMO) antenna diversity technique to mitigate the gross effect of signal loss. The field data measurement from a transmitting base station was collected using data analytics tools such as spectrum analyser, network planning tools and global positioning system (GPS) gadgets. The distances of the measurement points from the transmitting base station was recorded using GPS, while the received signal strength and signal-to-noise-ratio (SNR) calculation was done with the spectrum analyser and network planning tool. In this project, the received signal strength of SISO, SIMO, and MISO base station antenna systems were obtained from the simulation result of the field data; this showed high signal loss, while the result obtained using MIMO 4 x 4 antenna diversity resulted in 200% high signal gain and increased network coverage.
