China, for example, is a world leader in 5G deployment, having rolled out extensive 5G infrastructure in major cities and rural areas. South Korea was the first country to launch nationwide 5G services in 2019, and it continues to expand its network coverage. Meanwhile, the United States has seen multiple telecom giants like Verizon, AT&T, and T-Mobile invest billions of dollars in building out 5G infrastructure.
2.2 The Role of Government Regulations
Governments worldwide have recognized the strategic importance of 5G for both economic growth and national security. Regulatory bodies have been working to allocate the necessary radio spectrum for 5G use and to facilitate the deployment of the required infrastructure.
For instance, the Federal Communications Commission (FCC) in the U.S. has auctioned off valuable spectrum licenses to companies wishing to build 5G networks. Similarly, in Europe, regulatory agencies have worked to streamline the rollout process and ensure fair competition among network providers.
However, the deployment of 5G networks also comes with geopolitical challenges. For example, the U.S. and its allies have raised concerns about the involvement of Chinese companies like Huawei in the deployment of 5G infrastructure, citing potential security risks. As a result, some countries have placed restrictions on Huawei’s participation in 5G deployments.
