Your home DOES NOT need a Tri-band router.

1 band router → 1 RF transmitter

Dual-band → 2 transmitters

Tri-band (2.4 + 5 + 6 GHz) → 3 transmitters

Quad-band WiFi 7 → 4 transmitters

That’s 4 radios blasting 24x7

For 99% of households,

A simple router is enough.

2.4 GHz to go farther,

5 GHz to go faster.

End of story.
