Enhanching Data Rate and Coverage in Private 5G Network: A Comparative Study of 4×4 MIMO and 8×8 MIMO Antennas

Private 5 G is a promising wireless network technology providing wide ranging of new opportunities for mobile operators to allow customers to have enhanced capacities and end-user experiences in order to deal with the growing data demands. Nonetheless, prior to the installation of Private 5G, it is necessary to properly prepare the base, especially in selecting the most appropriate antenna and Radio Frequency (RF) band. This study aims to analyze the implementation of $4 \times 4$ MIMO and $8 \times 8$ MIMO antennas on the Private 5G Network in the industrial area of Greater Jakarta, covering an area of 35 km2, at a frequency of 2300 MHz and a bandwidth of 40 MHz. The research was conducted using data rate measurement scenarios and the number of sites was calculated based on the variations of modulations used. The results showed that using an $8 \times 8$ MIMO antenna obtained a higher data rate that was 2 times of the $4 \times 4$ MIMO antenna and only needed fewer sites of 0.25 times the $4 \times 4$ MIMO antenna. The coverage planning simulation also showed that the $8 \times 8$ MIMO Antenna had better SS-RSRP and SS-SINR values than the $4 \times 4$ MIMO Antenna with -93.27 dBm and 18,560 dB.
