As 5G technology advances, the network throughput could improve from 3-4 Gbps to 5-6 Gbps.

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.

This case study is part of the GSMA 5G Transformation Hub, demonstrating the world’s most innovative 5G solutions.
