One of the standout features of the KT GiGA WiFi Wave 2 is its support for MU-MIMO (Multi-User, Multiple-Input, Multiple-Output) technology.

MU-MIMO allows the Wave 2 router to communicate with multiple devices simultaneously. This means one person can stream 4K video while another plays competitive online games without either experiencing lag or buffering.
