In this section, we demonstrate proof of concept by testing the new formula for calculating the spectrum usage fee in Indonesian industrial areas. The calculation is for a 10-year license fee in the mmWave spectrum band with a bandwidth of 100 MHz. To ease reading, all the values have been rounded without displaying the decimal values. We take study cases focusing on the Jakarta region in two industrial areas: Pulogadung and KBN. Jakarta is the capital city of Indonesia, which may be considered an ideal example of 5G-mmWave private network vertical industry implementation. The Pulogadung industrial area is in Jakarta and is jointly possessed by the Republic of Indonesia and the Jakarta provincial government. It covers 500 ha (5 km\({}^{2}\)) and is home to 400 companies, while KBN is an Indonesian state-owned enterprise engaged in managing industrial areas located in Jakarta that cover 800 ha (8 km\({}^{2}\)). In 2020, the government of Indonesia held 73.15% of the company, while the Jakarta provincial government held the rest. The data about both industrial areas are shown in Table 6, in which columns) (3,4) are the names of the areas and rows (2-5) list basic information about them. We calculate the spectrum usage fee using the new formula, as shown in rows (6-10) of Table 6. These rows show the results for each type of industry--namely, chemistry, food and drink, automotive, textiles and clothing, and electronic. The total sum of all the industrial types is indicated in row (11) of Table 6.  
The explanation below demonstrates how to obtain such spectrum usage fee values. The calculation example is for the chemistry sector in the industrial area of Pulogadung. \begin{table}
