iPhone 5S with support for only single-stream 802.11n can achieve a maximum WiFi speed
of only 150 Mbps. As more devices connect and begin downloading, the bandwidth is shared
among them as well.
The following example of shared bandwidth shows a dual-band router in which the GHz WiFi
band has a fast 640 Mbps capacity. If only one computer or device connects, the router can
allocate a speed of up to 640 Mbps to that connection, assuming that the device is capable of
that speed. When more devices connect to the 5 GHz 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.

Total bandwidth: 640 Mbps
(150 + 300 + 150 + 1300 + 1300) ÷ 5

That means that in the network shown, a computer with a 1,300 Mbps capacity has an
effective WiFi connection speed of 160 Mbps (
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, having two 5 GHz bands means that the router has dedicated 5 GHz bands. That's like
