Sensitivity Options of 5G 700 MHz Network Deployment in Urban Models: A Simulation for Emerging Countries

Abstract

As one of Indonesia’s major urban cities, Bandung is seeing rising demand for high-speed wireless connectivity; this research performs a techno-economic analysis to evaluate the feasibility of deploying a 5G network to meet this need by utilizing the 700 MHz spectrum in the city. Capacity and coverage studies are conducted to determine the required number of base stations (gNodeB) and optimal network configuration for Bandung. Economic factors are analyzed, including cost structures, feasibility, and sensitivity parameters. Network simulations demonstrate that the 700 MHz band provides good coverage across Bandung, with an average SS-RSRP of-92 dBm and SS-SINR of 9.21 dB. The economic assessment shows a positive trend, with a net present value of $11.9 million, an internal rate of return of 33.09%, and a payback period of 3 years. However, 142 gNodeBs require substantial upfront investments of $2.7 million per site. In addition, the number of gNodeB is identified as the most sensitive parameter influencing project feasibility. While deploying 5G at 700 MHz offers good propagation and indoor penetration to serve Bandung, significant infrastructure funds are needed. By adopting long-term strategies, telecom operators can realize the technological and economic potential of 5G in Indonesian cities.
