"Download a 2GB high-definition movie in 0.5 seconds."
Transmission speeds 100 times faster than 3-band LTE_A

LG Uplus announced that it has successfully demonstrated for the first time in Korea a download transmission speed of up to 31 Gbps, which is over 100 times faster than the current 3-band LTE-A technology, using a test 5G base station at the technology lab in its Doksan-dong, Geumcheon-gu, Seoul building.

When LG U+'s 5G base station is commercialized, you will be able to download a 2GB high-definition movie to your phone in just 0.5 seconds.

This technology demonstration was conducted in collaboration with Huawei, a global network equipment manufacturer. LG Uplus's success in demonstrating a speed of 31 Gbps was due to the ability to apply 'Massive MiMO,' a key 5G network technology, to Huawei equipment capable of supporting ultra-wideband up to 1 GHz in the ultra-high frequency (mmWave) band.

Massive MIMO (Massive Massive Multiple-Input Multiple-Output) is a next-generation network technology that increases the number of digital signal transmission antennas connected to a single base station from 2-3 to over 100, enabling data transmission to multiple users simultaneously or large amounts of data to specific users.

By applying ultra-wideband support equipment for Massive MIMO, it is possible to provide high-speed 5G services to all users without any speed degradation even when multiple users are connected to a single base station at the same time, which will play a very important role in ultra-high-speed streaming services such as virtual reality (VR), augmented reality (AR), and ultra-high-definition (UHD) broadcasting.It is expected to be.

LG Uplus explained that this demonstration was significant in that it was conducted based on a 5G test base station and test terminals, and that it used the 28GHz frequency, which is being strongly considered as a 5G frequency in Korea.

LG Uplus is conducting service quality measurements and coverage tests in outdoor commercial environments in addition to laboratory tests to commercialize the 5G network as soon as possible once it secures 5G frequencies in the future.

LG Uplus's active participation in the early commercialization of 5G base stations in partnership with global equipment manufacturers is intended to flexibly respond to rapidly increasing data traffic while securing leadership in 5G networks through the introduction of next-generation network core technologies.

LG Uplus Network Technology Division Head Kang Jeong-ho said, "Ericsson previously demonstrated speeds of up to 26 Gbps through a 5G test base station, but the 5G technology-based base station and equipment demonstrated by LG Uplus in this demonstration can achieve speeds that are even faster than previously developed base stations." He added, "We expect this to greatly contribute to the activation of high-definition services such as 4K, 8K UHD, and VR in the future."
