## Appendix D
So the factors F are calculated according to the following equation:  
\[F_{x}=\left(\frac{NoIn_{U\text{A}x}\cdot\text{F}_{In\text{x}}}{NoIn_{State }}+\frac{BDP_{U\text{A}x}\cdot\text{F}_{GDP}}{BDP_{State}}+\frac{NoNTN_{U \text{A}x}\cdot\text{F}_{Roam}}{NoNTN_{State}}\right)\]  
where is:  
* NoInhUAx--The total sum of the population in each UAx (x = 1, 2, 3, 4 and A)
* NoInhState--The total population of that country,
* FInhx--Factor that describes the value of individual UAx for the potential of the telecommunications market ma (x 0 1, 2, 3, 4 and A),
* GDPUax--The sum of gross domestic product that is collected in UAx areas,
* GDPState--Gross domestic product in the country,
* FBDP--A factor that describes the importance of the income of business users in the telecommunications market of that country,
* NoNTNUX--Number of nights of foreign guests/tourists in UAx settlements (x = 1, 2, 3, 4 and A),
* NoNTNState--The total number of nights spent by foreign guests/tourists in the country,
* FRoam--The importance of roaming, that is, the income generated by foreign users in the country,
* FInh + FBDP + FRoam = 1. The factors F\({}_{\rm Inh}\), F\({}_{\rm GDP}\) and F\({}_{\rm Roam}\) are fixed and defined in advance depending on the indicators of their calculation and can be corrected on an annual basis. These factors represent the ratio of the financial value of the inhabitants' segment, the GDP segment and the guest users' segment to the total value of the telecommunications market and differ from country to country. According to the analyses carried out in B&H in 2021 (after the COVID-19 pandemic), the total factor values are F\({}_{\rm Inh}\) = 0.69, F\({}_{\rm GDP}\) = 0.26 and F\({}_{\rm Roam}\) = 0.05. The total sum of these three factors is one (1). The values of these factors are different in other countries, and if an analysis of the telecommunications market in those countries is carried out, it will be necessary to calculate them based on the available data. The seventh item in this area (the second item of the fixed subsection) gives the value of the telecom operator's potential with regard to accessibility to private users via fiber optic lines. In this item, the access speeds provided to users are not counted, but only the optical fiber infrastructure is analyzed. Internet access speeds (download/upload) can be increased simply by changing the terminal (end) equipment, but it is necessary to have a fiber-optic infrastructure that supports high Internet access speeds, and through such an infrastructure telecom can offer all new and advanced services to private users without speed restrictions transmission and signal delay. Because of these reasons, this item analyzes only the availability provided by telecom to private users through the fiber optic infrastructure. The equation is simple to calculate:  
\[QoFTTH=\left(\frac{NoFTTH}{NoHOMES}\right)\cdot 0.1\]  
where is:  
* QoFTTH--Quality of connection of fiber optic infrastructure to homes (private users),
* NoFTTH--Number of households connected by fiber optic infrastructure (FTTH--Fiber to the Home),
* NoHOMES--The total number of households (estimate if there is no exact number) in the observed area--can be an analysis on the territory of one city, region or the entire country. It is important to emphasize that when the development of this model started, this item was significantly different because it included the analysis of fiber optic infrastructure to buildings (FTTB) and to cabinets (FTTC--which were a link for several buildings or other facilities). As new services progress significantly (and users were reached by copper pair or coaxial cable, which is already a limitation for some advanced ICT services) and increasing demands are made for access bandwidth, these two items (FTTB and FTTC) were also deleted. From the equation, respectively, the factors F that defined their value have approached and equaled zero, and these parts are no longer taken into account during the calculation of this item.
