Successfully connected wirelessly between base station and test terminal in accordance with 5G international standard specifications

LG Uplus announced that it successfully demonstrated data communication based on the 5G international standard at Nokia in Finland, together with global equipment manufacturer Nokia and terminal chipset manufacturer Qualcomm.

This demonstration was conducted based on 'NSA (Non-Standalone)', which was approved as a 5G standard by '3GPP', the international 5G standardization organization, in December of last year. NSA is a method of transmitting data by combining 5G and LTE. Following the NSA standard, 3GPP is preparing the first standardization of 5G in the first half of this year, and various telecommunications and equipment companies around the world will develop 5G base stations and terminals in accordance with the 3GPP standard specifications.

Meanwhile, large global operators have often experimented with their own specifications rather than the 5G standard. In addition, the test was conducted only through a wired connection between the base station and the terminal, which was different from the actual wireless communication environment.

However, this time, not only did they proceed with the 5G international standard specifications, but they also successfully tested the base station and test terminal by wirelessly connecting them, thereby establishing a foundation for various equipment and terminal manufacturers to conduct field tests in an environment identical to the actual one together with LG Uplus in the future.

This demonstration utilized commercial base station equipment based on the 5G standard specifications currently being developed by LG Uplus and Nokia and Qualcomm test terminals, and demonstrated 5G services such as ultra-high-speed data communication and ultra-low-latency VR and video games in the 3.5 GHz and 28 GHz bands, which are the 5G standard frequencies.

These three companies agreed to begin developing equipment and terminals based on the 3GPP standard specifications last year and have been developing related equipment and terminals. LG Uplus plans to install standard-based 5G equipment in the 5G test field and upgrade equipment software and hardware for early commercialization of 5G.

Kim Dae-hee, executive director in charge of 5G strategy at LG Uplus, said, “We have achieved technologically advanced results through cooperation with global telecommunications companies such as Nokia and Qualcomm,” and “We will secure technological leadership by seeking cooperation with various domestic and foreign operators for early commercialization of 5G.”
