This chapter explains how the router manages WiFi connections for its WiFi bands and how you 
can control the relevant router settings.

Tri-Band WiFi
Tri-band WiFi delivers 3.0 Gbps combined WiFi speeds through three dedica\
ted WiFi 
bands—a 2.4 GHz band, plus two 5 GHz bands. This additional 5 GHz WiFi band allows you 
to double the WiFi bandwidth for dual-band devices.

Figure 7. Tri-band WiFi doubles the available bandwidth for dual-band devices
Smart Connect intelligently selects the best WiFi band for each dual-ban\
d device to optimize 
connection speed and performance based on that device’s speed and performance. The 
router automatically manages your WiFi connections, performing load bala\
ncing across the 
two 5 GHz radios. This additional WiFi bandwidth combined with the intelligence to segrega\
te 
traffic based on WiFi speed and load balancing provides the best performance\
 for multiple 
wireless devices in the home.
How Tri-Band WiFi Improves Speed and Performance
Tri-band WiFi increases the available WiFi bandwidth for your network to \
reduce network 
congestion. 
Typically a dual-band WiFi router shares bandwidth among all connected de\
vices that are  downloading data at the same time. So if you are watching a Netflix movi\
e on your 
Internet-enabled large-screen 

TV while your kids are watching a YouTube video on a 
smartphone, the router shares the bandwidth across these two devices. This is particularly 
unfair for the faster 802.11ac devices or three-stream (3x3) 802.11n devices because their 
speeds are reduced to the speed of the slowest device in the network. Ev\
en one slow device 
can bring down the entire network speed.
In this simplified example, the 5 GHz band is capable of a maximum speed\
 of 1300 Mbps, but 
the actual speed could be limited by the device capability
 . For example, an Apple MacBook 
Pro with support for three streams is capable of the maximum 1300 Mbps b\
ut the 
						

							Tri-Band WiFi Connections 69
 Nighthawk
 X6 AC3000  Tri-Band WiFi  Router
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 wh\
ich 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 b\
y 5, as shown in the 
following figure.

(150 + 300 + 150 + 1300 + 1300) ÷ 5

Figure 8. Dual-band WiFi network with one 5 GHz WiFi band
That means that in the network shown, the effective connection speed of a computer with a 
1,300 Mbps is 160 Mbps (
1300 5 ), 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 ba\
nds. 

That’s like

Figure 9. A tri-band network offers two dedicated 5 GHz bands
In this tri-band network, the first 5 GHz band is 200 Mbps, and the spee\
d of the second 5 
GHz band is 1,300 Mbps. 
The slower and faster devices are separated in different WiFi connections to ensure that you  get the best speed on each device. So in the previous figure, all the th\
ree mobile devices are 
on one 5 GHz band with a combined maximum speed of 200 Mbps, and the oth\
er 5 GHz WiFi 
band is used for the faster 802.1

1ac devices with a combined maximum speed of 1300 Mbps. 
Effectively both slower and faster devices can run faster and the overall \
network speed 
increases by more than two times, from 450 Mbps to 1500 Mbps.
Load Balancing
The router uses load balancing to distribute WiFi connections among all \
three WiFi bands to  ensure that both the WiFi bands are utilized. Load balancing avoids over\
loading a single  
5 GHz band and ensures that both the WiFi bands are utilized and device \
connections are 
spread across the two bands.
