Samsung is working on speeding up Wi-Fi services in subways, and it recently demonstrated how 5G mmWave technology can boost legacy Wi-Fi network speeds in these environments.

Samsung trialed the technology in parts of Seoul Metro, and more specifically, the test covered five stations in major downtown areas. Samsung used its 5GmmWave Compact Macro solution for the test, which was installed along the railways.

The system achieved ~25x faster speeds than current solutions

According to Samsung, the current average network speed achieved in the Seoul Metro network is 71Mbps. But after testing the 5G mmWave Compact Macro solution as a backhaul, the company claims to have reached a transfer rate that is 25 times faster than the current solution.

In telecommunications terms, a backhaul is a network component that links the core network to smaller subnetworks.

Samsung reached Wi-Fi downlink speeds of 1.8Gbps on a moving subway train using the Galax S21 Ultra and the Compact Macro 5G mmWave solution. The Compact Micro was introduced in June, and as the name implies, it’s a compact 5G solution that includes a baseband unit, radio, and antenna in a single device.

The Korean tech giant’s 5G technologies are also used to boost network speeds in crowded areas such as stadiums, shopping malls, and hospitals. And with the first test run complete, the Samsung Compact Micro could soon bring 5G to your mobile device in subways outside of South Korea.
