## 3 The Proposal
### Determining Grids Based on 17 Indicators
There are 1938 districts on this island, counting 17 Grid #1 districts, 810 Grid #2 districts, 857 Grid #3 districts, and 254 Grid #4 districts, as illustrated in Figure 9.  
Java Island has six provinces named Banten, East Java, Yogyakarta, Central Java, West Java, and Jakarta. There are 2143 districts on this island, none of which are Grid #1 districts, but 232 districts are Grid #2, 1209 districts are Grid #3, and 702 districts are Grid #4, as illustrated in Figure 9.  
Kalimantan Island has five provinces named North Kalimantan, East Kalimantan, South Kalimantan, Central Kalimantan, and West Kalimantan. The number of districts on this island is 619, among which 23 districts are Grid #1, 264 districts are Grid #2, 260 districts are Grid #3, and 72 districts are Grid #4, as illustrated in Figure 9.  
Sulawesi Island has six provinces named West Sulawesi, Gorontalo, Southeast Sulawesi, North Sulawesi, Central Sulawesi, and South Sulawesi. The number of districts on this island is 1021, among which 25 districts are Grid #1, 548 districts are Grid #2, 376 districts are Grid #3, and 72 districts are Grid #4, as illustrated in Figure 9.  
The Lesser Sunda Islands comprise three provinces, namely East Nusa Tenggara (NTT), West Nusa Tenggara (NTB), and Bali. The number of districts on this island is 483, among which 15 districts are Grid #1, 225 districts are Grid #2, 176 districts are Grid #3, and 67 districts are Grid #4, as illustrated in Figure 9.  
The Maluku and Papua Islands have four provinces named West Papua, Papua, North Maluku, and Maluku. The number of districts on this island is 1028, among which 505 districts are Grid #1, 379 districts are Grid #2, 121 districts are Grid #3, and 23 districts are Grid #4, as illustrated in Figure 9.  
As demonstrated in Tables 11 and 12, the following conclusions were drawn from the validation results. Supplementary Material File S8 contain 1 figure (Figure S13) provides information on the verification procedures used to confirm the results. The accuracy ranges from 89 to 95.5%. falls into, we developed a novel multi-stage statistical approach involving 17 indicators of telecommunications network and socioeconomic factors. This paper's application of the proposed framework yields a grid representation of 7232 districts distributed across Indonesia's six major islands. This framework was applicable on a global scale for future work seeking to resolve the issues of disparity in access to telecommunications between the \"rich and poor\" groups in \"urban and rural/remote\" locations. With the assistance of this grid framework, telecommunications signals can be made available in all regions, thereby enhancing the global economy's efficiency and competitiveness, allowing for improved public service delivery (such as health and education) while providing the underprivileged with new employment and income opportunities. The comparison between study topics and important findings are presented in Table 13.  
The concepts of connectivity and digital development encompass many variables, perspectives, and areas of emphasis. In order to summarize the many variables that contribute to connectivity and digitalization, we propose a framework that can be used as a reference for the Indonesian government for constructing the nation's telecommunications infrastructure. Since this paper is full of academic research approaches and mathematical model perspectives, we expect that the results of our work will become valuable input for further policy development in Indonesia. As such, the creation of such policies will be enriched by an academic perspective, completing the typical socio-political considerations of policy development. It is also believed that our proposed framework has a very significant and potentially practical impact that could be replicated in multiple developing countries where millions of people are not yet covered by mobile telecommunications services.
