Feasibility Analysis the Implementation of the Dual Spectrum Licensed and Unlicensed Enhanced License Assisted Access (ELAA) on LTE Networks with the Techno-Economic Method

Each year, internet user traffic is growing, causing a surge in data service traffic while spectrum availability is increasingly limited, which results in gaps in capacity requirements. Telecommunications service providers can respond by improving quality in anticipation of an increasingly high demand spectrum. Enhanced License Assisted Access (eLAA) technology on Long Term Evolution (LTE) networks that utilize unlicensed spectrum technology as an additional channel, is expected to be a solution in increasing capacity and throughput. In this research, an enhanced license assisted access implementation planning scenario is implemented using the dual spectrum method with spectrum licensed 900 MHz, 1800 MHz, 2100 MHz, 2300 MHz, and 5 GHz unlicensed spectrum. The dimensioning capacity method is used as a technical analysis method to get the number of cells and eNodeB. The NPV, IRR, and payback period methods are used as a methodology for measuring financial feasibility. In this study, obtained the most suitable scenario to be implemented is the second scenario, the frequency used is 1800 MHz and 5 GHz frequency with a bandwidth of 20 MHz with an initial investment of $ 1,602,487.48, resulting in an NPV of $ 496,543.49, an IRR of 16,385%, and a 3 year 3 month Payback period.
