Case Study: How High-Capacity 5G Could Transform Subway Travel

South Korea’s Ministry of Science and ICT (MSIT) is looking to dramatically improve the Wi-Fi available on Seoul’s subway trains by using high capacity 5G networks to connect access points to the Internet. By harnessing 5G networks operating in high-frequency millimetre wave (mmWave) spectrum, MSIT expects to enable subway passengers to watch videos in 4K resolution on their mobile devices – something that isn’t possible with the in-train Wi-Fi coverage today.
