Techno-Economics Analysis for Dynamic Spectrum Sharing (DSS) Implementation of 5G Non- Standalone Networks at Frequency of 2100 MHz using Sensitivity Analysis Method

5G New Radio (NR) is the next generation of mobile cellular networks following 4G Long Term Evolution (LTE). 5G technology is becoming increasingly popular, which encourages telecom operators to be able to provide 5G services to customers. With the limited number of 5G users, the investment to provide 5G services is very high. Operators can provide seamless services to 5G subscribers by interworking with 4G networks. 5G interworking with 4G not only provides speed and seamless coverage but also viability solutions for the operator. The development of the 5G NR network requires additional frequency spectrum or uses the same frequency as the previous technology. Dynamic Spectrum Sharing (DSS) is a solution where operators can share spectrum between two different technologies. 5G DSS network planning is carried out using the coverage and capacity planning methods, followed by a business feasibility analysis and a sensitivity analysis. In Techno’s analysis for the deployment of the 5G DSS networks in Bandung, based on the results of coverage and capacity planning, 362 sites are identified that are needed to serve customers until 2029. In economic analysis, the NPV is 35.389 billion rupiah, the IRR is 13%, and the payback period is 5 years and 9 months. In the calculation of the sensitivity analysis, the data obtained shows that the user parameter, packet data price, and payload projection have a sensitive value of -4%, whereas the sensitivity for Capex is 22% and the sensitivity for Opex is 9.30%.

I. Introduction

5G technology is increasingly popular and encourages telecom operators to be able to provide 5G services to customers. With the limited number of 5G users, the investment to provide 5G services is very high. In the early stages of development, 5G service coverage is limited to the coverage area.
