"The Ministry of Science and ICT said it wanted to add up to 2,640MHz of bandwidth by 2026 to the currently allocated 2,680MHz for use in 5G networks. the additional bandwidths will be to prepare for the traffic explosion and use in new industries that will be 5G-based.
5G-based industrial applications will require massive amounts of data traffic that has not been seen before. As 5G expands into the market, carriers will seek out a broader spectrum to provide reliable services." – Sujeong Lim
