Table 1: Summary of articles included in the review. Figure 2: Publications per year related to the topic. Regarding the origins of the studies, the country with the highest number of relevant works was China, with 31.80% (\(n=14\)) of the total. This was followed by a considerable contribution from India, 20.50% (\(n=9\)). The US was in third place, with 6.70% (\(n=3\)). Spain, the United Kingdom, Taiwan, and Pakistan were in fourth place, each with a contribution of 4.50% (\(n=2\)). Other countries, such as Brazil, Indonesia, Tunisia, Saudi Arabia, Japan, Bangladesh, Italy, Greece, and Finland, presented individual contributions of 2.3% (\(n=1\))--that is, only one article each. It should be noted that the countries mentioned above are \begin{table}

Table 1: _Cont._mostly developed countries. In addition, several of them have 5G networks. On the other hand, from the South American continent, we found only one study (Brazil), which implies that most countries in this region have not yet implemented a 5G network, so research on this topic is limited.
