U+ Applyes '5G DU' to Commercial Network for Twice the Data Processing
Published2019.08.01 14:415G base station equipment is becoming smaller.
LG Uplus announced on the 1st that it has developed a high-capacity 5G Digital Unit (DU) capable of processing more than twice as much data as existing ones by promoting the lightweighting and integration of base station equipment to efficiently and easily secure 5G coverage, and has started applying it to its commercial network.
The 5G DU performs the role of converting signals received through the AAU (Active Antenna Unit), which exchanges wireless signals with smartphones, into digital signals and transmitting them to core equipment.
The high-capacity 5G DU doubles the AAU capacity compared to the existing one, allowing 36 AAUs to be connected to the DU, up from 18 as before. This is the first time in Korea that a high-capacity 5G DU commercial network capable of connecting 36 AAUs has been applied.
In addition, the subscriber traffic processing capacity has been increased 2.5 times from 20Gbps to 50Gbps due to the increase in AAU capacity, allowing customers to continue using the service without speed degradation in areas where high-capacity 5G DUs are deployed.
By increasing the integration density and reducing the weight of the equipment during the DU design, the AAU capacity was doubled, yet it was developed to be the same size as the existing equipment, thereby increasing the efficiency of the national office space.
Power consumption has also improved. The existing DU requires two units to accommodate 36 AAUs, with each unit requiring 1.33KW of power, for a total of 2.66KW. The new high-capacity DU requires only one unit and reduces power consumption to 0.89KW, enabling a power saving of over 66% compared to the existing system. By reducing power consumption, it has become possible to install more environmentally friendly equipment.
Lee Sang-heon, Head of Network Development at LG Uplus, said, “We have started building 5G high-capacity DUs centered on Seoul and the metropolitan area,” adding, “This has enabled us to expand coverage and provide services more efficiently and quickly in line with the increase in subscribers.”

SKT and Samsung Electronics Take First Step Toward Commercialization of 5G SA Service
SK Telecom announced that it has successfully achieved data communication using a pure 5G system by interconnecting a 5G SA packet switch, which is Korea's first 5G standalone standard equipment, and core equipment together with Samsung Electronics. A packet switch is an essential gateway through which all voice and data traffic generated from mobile devices such as smartphones must pass in order to access the internet network. The current 5G network operates in NSA mode, which partially shares equipment with LTE. 5G SA, which configures the network with 5G equipment only, requires significant time, cost, and resources for standardization and development. The 5G SA presented this time demonstrates data processing efficiency three times higher compared to the existing 5G NSA. It can efficiently control large-scale traffic and provide optimal communication performance for next-generation services expected in the 5G era, such as AR/VR, autonomous driving, smart factories, and smart farms.

SK Telecom First Applies AI-Based Network Operations at Gwanghwamun K-Pop Concert
SK Telecom announced that it applied an AI-based network operation system for the first time at a large-scale K-pop concert held in the Gwanghwamun area of Seoul on March 21st, managing communication quality throughout the event. Mobile data usage during the three hours before and after the concert reached 12.15TB, approximately doubling compared to the same time slot the previous weekend. SK Telecom monitored traffic using the AI system 'A-One' in five-minute and 50-meter units to respond to potential overload situations, while also operating temporary communication facilities and on-site personnel in parallel. This case is interpreted as confirmation of the practical applicability of AI-based autonomous network operation in an environment where demand from dense events and foreign users increases simultaneously.
