LG Uplus is applying the 'CoMP (Coordinated Multi Point)' function, a cooperation technology between base stations that improves speed quality in base station boundary areas, to its 5G commercial network for the first time in the world.

COMP is a base station cooperation technology that eliminates frequency interference in boundary areas between base stations and enables simultaneous data exchange with multiple adjacent base stations. Because the same data is received redundantly, the signal strength increases, improving speed quality.

Smartphone terminals exchange data with a single base station that has a strong signal strength, but base stations using the same frequency create boundary areas where frequency signals overlap, and frequency interference occurs in these boundary areas, causing a decrease in speed.

An official from LG Uplus stated, “This is the world’s first application of the COMP function to a commercial 5G network,” adding, “We have confirmed that download speeds improved by approximately 20% in boundary areas between base stations where speed quality had previously degraded.”

LG Uplus plans to first apply the COMP function to base stations in the Seoul metropolitan area and then expand it nationwide.

Park Song-cheol, Head of the NM Development Group at LG Uplus, stated, “Building on the improvement of quality in border areas through the application of the COMP function, we plan to continuously expand 5G coverage while simultaneously developing and commercializing quality improvement functions.”
