5G Core Equipment that Restores and Transmits Attenuated Signals
Plans to Apply to Commercial Networks Upon Completion of Performance Verification

LG Uplus and Nokia jointly developed the 'Wireless BackHole Node,' a key 5G equipment, and unveiled it at MWC 2017.

This equipment relays radio waves by bypassing obstacles to ensure seamless data reception when users are far from the 5G base station or when radio signals are blocked by obstacles such as buildings during the transmission of UHD videos and other content from 5G base stations to smartphones.

The wireless backhaul base station not only amplifies radio signals but also restores attenuated signals during transmission to their original state and transmits them, extending the coverage range and improving data transmission rates.

Additionally, since radio signals are transmitted from other base stations, no separate wired cables are required, reducing construction costs. Compared to LTE base stations, it is lighter in weight and smaller in size, making it easy to install on traffic signals or telephone poles.

Meanwhile, Nokia unveiled the wireless backhaul equipment at the MWC event in Barcelona, Spain. LG Uplus plans to consider applying the equipment to commercial networks according to the 5G service schedule once performance verification is completed.

Park Song-chul, Senior Executive of LG Uplus's Network Technology Group, stated, "LTE base stations are built so densely nationwide and repeater prices are inexpensive, so the necessity for developing wireless backhaul equipment has not been high until now. However, with the advent of the 5G era, the utilization of this equipment, which enables efficient coverage acquisition, is expected to increase significantly."
