Unlike Wi-Fi 5, which handles one device at a time per channel, the F6640 uses (Orthogonal Frequency Division Multiple Access). This allows the router to communicate with multiple devices simultaneously. If your household has 20+ connected devices (smart TVs, phones, tablets, security cameras), you will notice significantly less lag and buffering.
Why the vertical design? ZTE engineers have optimized this for thermal dissipation. Unlike flat routers that trap heat, the F6640 uses convection currents to pull cool air in from the bottom and expel hot air out the top. For users putting this in a cabinet, this is a breath of fresh air.
