### Economic Impact of 5G-mmWave Private Network in Industrial Areas  
Translating the I-O model to our case, the input is the total CAPEX and OPEX cost of deploying 5G-mmWave private networks that will impact economic output. To do so, we first calculate the total CAPEX and OPEX cost in the industrial area over a 10-year period. The total CAPEX and OPEX cost of deploying 5G-mmWave private networks is determined by the following factors: base station core network construction, installation, and maintenance, optical fiber installation and maintenance, and spectrum usage fees. We then estimate a 10-year capital expenditure schedule from 2021 to 2031, with the assumption that all costs are fixed costs [51]. In Table 7, row (15) defines the final total CAPEX and OPEX cost of deploying 5G-mmWave private networks in each industrial area. The values result from our calculations applying the engineering economic method [24] to each industrial area. The input for the I-O model is the cost of 5G-mmWave private network deployment We assume that the impact can be ascertained in the 17 sectors officially defined by the Indonesian government [46; 52]. These 17 sectors should be affected by the input of the 5G-mmWave private network deployment cost listed in Table 7, column (1) rows (2-18). The sectors range from agriculture to health services, taking in various miscellaneous sectors. Table 7, column (2) defines the value of the multiplier. The multiplier is the proportional increase or decrease in the final income that results from an injection or withdrawal of spending. Table 7, columns (3) and (4) list the results of the I-O model that yield the output, or economic impact, due to the input of the 5G-mmWave private network deployment cost. Table 7, columns (3) and (4) indicate the impact on the 17 sectors when the 5G-mmWave private network is deployed in the Pulogadung and KBN industrial areas, respectively. The overall sum of these sectors is listed in row (19). \begin{table}
