Figure 8. A tri-band network includes two dedicated 5 GHz bands
In this tri-band network, the first 5 GHz band provides a speed of 200 Mbps, and the second 5 GHz band provides
a speed of 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 three mobile devices are on one 5 GHz band with a combined maximum
speed of 200 Mbps, and the other 5 GHz WiFi band is used for the faster 802.11ac 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 640 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 prevents overloading a single 5 GHz band and ensures that both the WiFi
bands are utilized and device connections are spread across the two bands.
For example, if three mobile devices are connected to one 5 GHz band, the fourth device is automatically connected
to the other 5 GHz band.

Figure 9. Load balancing
Slower devices like printers, older computers, or IP cameras connect to the 2.4 GHz band. The presence of two 5
GH bands prevents overloading when many devices use WiFi at the same time.
Benefits of Tri-Band WiFi
The tri-band WiFi network outperforms the dual-band network in several ways:
•
More bandwidth is available.
Even with more devices connected to the network, because the connections are spread across two different
bands, each device gets a larger share of the available WiFi bandwidth.
•
Smart Connect directs WiFi traffic to the appropriate lane.
With Smart Connect, older devices do not slow down faster devices.
•
The router uses load balancing to avoid network congestion in each WiFi band.
With load balancing, you don’t need to share your WiFi connection with as many devices.
Smart Connect
Smart Connect balances your 5 GHz WiFi connections into two different radio bands: the 5 GHz radio 1 band and
the 5 GHz radio 2 band. The router uses Smart Connect to choose the best radio band for your device to give you
the best WiFi performance.

iTunes Server lets you play music with your Windows or Mac iTunes app from a storage device that is connected
to the router.You can also use the Apple Remote app from an iPhone or iPad to play music on any AirPlay devices,
such as Apple TV or AirPlay-supported receivers.
Figure 10. Smart Connect
For Smart Connect to work, both 5 GHz radio bands must use the same WiFi network name (SSID) and network
key (password). That means that when you connect to the router with WiFi, you see only one 5 GHz SSID that
connects to both 5 GHz radio bands.
If you enable Smart Connect and the SSID and passwords for both 5 GHz radio bands do
not match, the WiFi settings for 5 GHz radio 1 overwrite the WiFi settings for 5 GHz radio 2.

Beamforming
Beamforming means that your router actively tracks clients and directs Wifi to the client, rather than just blasting it
out in all directions. This means better WiFi range and performance for your WiFi devices.
The router uses explicit and implicit beamforming to improve WiFi performance. Explicit beamforming requires the
client to support beamforming. Typically, 802.11ac clients support beamforming. Implicit beamforming means that
the router can support beamforming even with clients that do not support beamforming.This router supports implicit
beamforming for both 2.4 GHz and 5 GHz clients, which means that it will provide beamforming benefits of better
range and performance for all WiFi devices, even older 802.11a/b/g/n devices, not just the latest WiFi clients.
Enable or Disable Implicit Beamforming
Implicit beamforming means that the router can use information from client devices that support beamforming to
improve the WiFi signal.
To enable or disable implicit beamforming:
1.
Launch a web browser from a computer or WiFi device that is connected to the network.
