A:Answer Tri band uses a third frequency on the 5Ghz channel (5.8 GHz), which typically has less traffic. This band is usually used in Wi-Fi 6 mesh system between mesh point devices. Tri band 5 and 6, I guess is what you’re referring to Wi-Fi tri band? similar concept, except newer standards, ax vs ac chips, with faster connection, more devices, etc, and better for “home automation” I think.
