Field tests conducted in the 3.5GHz and 28GHz frequency bands

LG Uplus announced that it has opened a new 5G test base station near Gangnam Station in Gangnam-gu, Seoul, and has started testing 5G technology and services in a real-world environment using the 3.5GHz and 28GHz frequency bands.

The Gangnam area is useful for testing 5G technologies and services targeting users in an urban environment with high population density, large-scale data usage, and many obstacles that make it difficult to bypass radio waves, due to the large floating population and high-rise buildings.

LG Uplus plans to establish a 5G cluster centered around a new 5G test base station to serve as a hub for preparing 5G technology and services.

First, utilizing the 3.5GHz and 28GHz frequency bands, which are likely candidates for 5G frequencies, we will test the coverage and inter-frequency interference of 5G technology and conduct field tests on transmission speeds so that the most efficient 5G network can be configured without dead zones.

Last September, LG Uplus successfully demonstrated a field test of dual connectivity technology that combines 3.5GHz and 28GHz to provide a transmission speed of 20Gbps, the first of its kind in Korea.

In addition, we plan to conduct interoperability tests with frequencies such as 800MHz, 2.6GHz, and 1.8GHz, which are currently being used to provide LTE services.

5G buses will also be introduced and operated. The 5G bus will be equipped with 5G test terminals and will drive through a 5G cluster to conduct mobility tests for providing seamless 5G services between base stations and terminals.

In particular, at the '5G Global Event' to be held in Seoul from November 22 to 24, LG Uplus is set to play a leading role in promoting the excellence of its 5G technologies and services by providing VIPs from around the world attending the event with the opportunity to experience dual connectivity technology, which enables high-speed transmission speeds by combining 3.5GHz and 28GHz frequencies while on the move, as well as real-time IPTV services based on FWA (Fixed Wireless Access).

"We are steadily making preparations not only in technical aspects but also in service aspects, such as recently succeeding in demonstrating core 5G technologies and services like frequency aggregation technology," said Kim Dae-hee, Senior Vice President of 5G Strategy at LG Uplus. "We plan to lead the way in 5G, just as we did with LTE, by consistently preparing for 5G that all citizens, not just a select few, can enjoy."
