This is the first time in Korea that specialized design tools have been introduced for 5G in-building design, and LG Uplus achieved download speeds of over 1Gbps with 5G in-building equipment last October.
Since 5G frequencies (3.5GHz) are high-frequency bands with high signal and penetration losses, high-quality services can only be provided by undergoing accurate design and simulation processes starting from the in-building coverage construction phase.
LG Uplus collaborated with Ivy Wave to discover 5G in-building design standards and construction methods, and carried out 5G network design at Samsung Lions Park in Daegu, Changwon NC Park, and Daegu World Cup Stadium.
In addition, the quality of the 5G in-building dedicated small cell, which was pilot-installed and operated at Gangbyeon Technomart in Gwangjin-gu, Seoul, was measured using the National Information Society Agency (NIA) app, and it was confirmed that the 5G download speed improved by an average of 37%.
The equipment in question consists of several connected to the antennaBy enabling the simultaneous construction of transmission lines, it became possible to implement a 4x4 MIMO environment inside a building, which was previously difficult to implement indoors, thereby increasing download speeds. Since the antenna output and propagation efficiency are higher than those of existing in-building equipment, it is also possible to provide service to a wider area.
In addition, since the antenna cell settings can be remotely adjusted, it is possible to respond quickly by distributing users by antenna even when there is a surge in users, while minimizing downtime to ensure smooth service provision.
Park Song-cheol, Head of NW Technology Operations Group at LG Uplus, said, “Based on our LTE in-building design know-how, we have implemented an optimal design using Ivy Wave to install new in-building equipment in the right places and secure a solution that enables perfect use of 5G services even indoors,” adding, “We plan to continue doing our best to improve in-building 5G quality.”
IvyWave is a specialized in-building design tool that predicts user coverage by considering the building's internal structure, interior materials, and living spaces through radio wave simulations in indoor environments.

LG U+ Commercializes World's First 5G Wireless Network Remote Optimization Technology
LG Uplus has become the world's first company to commercialize '5G wireless network remote optimization' technology, which enables remote adjustment of the service coverage and direction of 5G base station antennas to optimize wireless networks. To this end, LG Uplus has independently developed a system that automatically collects 5G wireless network quality data and automatically detects locations with poor service from the collected data. This enables quality optimization without on-site dispatch and accelerates the time required to optimize 5G wireless network quality.
