In 2017, when KT introduced the Wave 2, it was marketed as a "pre-5G WiFi" experience. The core advancement was its adoption of the standard. At the time, this was a cutting-edge technology found only in premium, expensive routers. By integrating it into a home router, KT made enterprise-grade features accessible to the average household, promising a more stable and faster wireless environment.
2x2 MIMO (Multiple-Input, Multiple-Output) external high-gain antennas
Beamforming detects the physical location of connected devices and focuses the wireless signal directly toward them. Instead of broadcasting Wi-Fi in a generic circle, the targeted signal improves range, penetrates walls more effectively, and eliminates dead zones. Smart Band Steering
The primary advantage of KT GiGA WiFi Wave 2 is its speed. It supports theoretical speeds of up to . This makes it more than capable of handling high-speed gigabit internet plans offered by KT. kt giga wifi wave 2
Cons
While newer Wi-Fi 6 (802.11ax) and Wi-Fi 7 routers are now available with speeds up to 4.8 Gbps or higher, the GiGA WiFi Wave 2 remains a reliable standard for users with 500Mbps or 1Gbps internet plans . Comparison Table: KT GiGA WiFi Generations GiGA WiFi (Wave 1) GiGA WiFi Wave 2 (2.0) 867 Mbps - 1.3 Gbps 1.73 Gbps (Theoretical up to 3.4 Gbps) MIMO Support SU-MIMO (Single User) MU-MIMO (Multi-User) Channel Width Max Connections 128 - 256 users 256+ users Primary Use Standard Home Use High-Speed Public/High-Density Home Practical Usage Tips
: Focuses the wireless signal directly toward connected devices rather than broadcasting in all directions, which improves range and stability . Performance vs. Newer Standards In 2017, when KT introduced the Wave 2,
The "Wave 2" in the name is not marketing fluff. It ensures the router can handle the full 1 Gbps fiber connection that KT provides.
