"South Korea's 5G Dreams: A Reality Check"

South Korea, which led the world in the rollout of 5G, has not seen the promised advancements in network speeds and new technologies. While the country boasts the world's fastest 5G speeds and high adoption rates, the network has fallen short of its initial promises. Technical hurdles and cost constraints have limited the deployment of faster 5G speeds on a wider scale. South Korean telecom firms chose not to use the high-frequency millimeter-wave band, which offers extreme boosts in speed but has limited coverage. The lack of killer apps and low market demand have also hindered the widespread adoption of 5G services.
