band, they must share the bandwidth. If four devices connect, then the router divides its 640 Mbps capacity by 5,
as shown in the following figure.

That means that in the network shown, a computer with a 1,300 Mbps capacity provides an effective WiFi connection
speed of 160 Mbps (13005 ), and other devices would also see their WiFi speeds divided by 5.
Tri-band WiFi adds a second 5 GHz WiFi band to the network. This increases the available WiFi bandwidth, which
can be compared to widening the road. In addition to widening the road, using two 5 GHz bands means that the
router has dedicated 5 GHz bands. That’s like tri-band WiFi connections using two lanes in the wider road instead
of one. The router automatically uses Smart Connect to allocate the fastest devices to the fast lane.
