Company Overview

LG U+ (LG유플러스) is a mobile network operator and telecommunications service provider in the Republic of Korea (South Korea). The company was founded in July 1996 following the Korean government's decision to privatise Korea Telecom and subsequently open the telecommunications market up to the private sector. LG Electronics secured a CDMA operating licence under its subsidiary LG Telecom and launched a national digital cellular network. To improve its whole-of-business offerings, LG merged subsidiaries LG Dacom and LG Powercom in July 2010, and rebranded the new entity as LG U+.

The company has provided CDMA services since 1997 over the 1800 MHz band, and has opted not to develop a 3G UMTS network.

LG U+ launched 4G LTE in July 2011 using a 10 MHz channel of B5 (850 MHz). A dual-carrier network was developed in July 2012 with the addition of B1 (2100 MHz), with LTE-A 2C carrier aggregation implemented July 2013 supporting DL rates up to 150 Mbps. Following the August 2013 auction, LG U+ secured an additional 40 MHz of 2600 MHz spectrum and implemented B7 (2600 MHz) in mid-2014, permitting peak data rates of up to 225 Mbps using 2C aggregation of the new band.

The company became the first South Korean operator to implement 3C aggregation (300 Mbps - CA_1A-5A-7A), deploying the feature nationally by July 2014. LTE-Advanced Pro was tested in November 2015 achieving 1.2 Gbps using both 4X4 MIMO and 256QAM technologies. LG U+ has also tested LTE-U LAA, 4C aggregation, and UL 2C CA.


LG U+ formed a partnership with KT and Huawei to begin deploying a joint national NB-IoT network shared between the two networks. The network was commercially launched July 2017 using a 200 kHz channel in the B3 (1800 MHz) band.

LG U+ 5G

The company has performed extensive 5G testing with its partner Huawei. The tests include a dual-band network comprising n78 (3500 MHz) and n257 (28 GHz), demonstrating peak data rates in excess of 20 Gbps. After securing 80 MHz of 3.5 GHz spectrum in the June 2018 auctions, along with 800 MHz of 28 GHz spectrum, LG U+ launched its 5G network in April 2019 over the n78 (3500 MHz) band. The initial network launch comprises over 10,000 Huawei 5G base stations.

News & Developments

[Seoul, Korea, November 24, 2017] During the 4th Global 5G Event, LG U+ partnered with Huawei to complete the world's first large-scale 5G network test in a pre-commercial environment in Gangnam District, Seoul. This network consists of both 3.5 GHz and 28 GHz base stations.

[Seoul, Korea, October 19, 2017] LG U+ and Huawei have successfully completed ‘Dual-Connectivity’ technology verification during a 5G field test in Seoul. ‘Dual-Connectivity’ technology provides a 20Gbps downlink rate by linking a 3.5GHz base station with a 28GHz base station. This verification showcases a major achievement made by LG U+ and Huawei in 5G joint innovation.

[Seoul, South Korea, September 12, 2017] In the Sangam area of Seoul, a hotspot for digital and media businesses, LG U+ and Huawei successfully completed the first phase of their 5G intensive urban field test. This 5G field test was designed as commercial-oriented and realized by an end-to-end 5G network with 5G gNodeB, Ng Core and a 5G mobile bearer network.
