In our earlier posts we talked about how Wi-Fi 6 is being promoted by South Korea's ministry and also how mmWave has not been very successful in Korea. Having said that, earlier last year, Samsung Electronics announced that it has signed contracts with all three South Korean operators to supply its 5G mmWave network solutions and boost connectivity for passengers on the Seoul subway system:
Over 3.6 million passengers use the Seoul subway daily across over 300 stations. With a population of 9.6 million, Seoul is one of the world’s most densely populated cities, with its subway serving as one of the major means of public transportation for the busy metropolitan area. The subway system is expansive, resembling a spider web network that connects Seoul and the surrounding areas, carrying over 30 percent of the city’s population.
While the Seoul subway system has already been providing stable 5G (3.5GHz), 4G and Wi-Fi services, mobile data demands in subways continue to rise exponentially as Korea’s monthly average 5G data consumption reaches approximately 25GB per person.

Later this year, Samsung’s 5G mmWave solutions will enable the subway’s Wi-Fi services to meet increasing data demands by leveraging mmWave’s wide bandwidth, extensive capacity and massive throughput. Subway passengers will be able to enjoy bandwidth-intensive applications such as high-speed, superior-quality streaming for live sports games, movies, mobile games and video communications. These will be delivered at Wi-Fi speeds up to ten times faster on average than currently provided.
In addition to transforming the daily mobile experience for subway users, Samsung’s advanced 5G mmWave solutions will drive a diversified range of use cases and business opportunities for new entrepreneurs, app development startups and consumers. Utilizing mmWave bandwidth can not only bring to life next-generation services such as the metaverse, cloud gaming and Extended Reality (XR) remote learning, but it can also be expanded beyond transportation to industries like retail, medicine, media and entertainment.
A key component of the Seoul subway commercial deployment is Samsung’s mmWave 5G radio solution, Compact Macro, which brings together a baseband unit, radio and antenna in a single form factor. Optimized for mmWave 5G, it uses in-house modems, radio frequency integrated circuits (RFICs) and digital analog front end (DAFE) ASICs.
