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 in a tri-band WiFi network
Slower devices like printers, older computers, or an IP camera connect to the 2.4 GHz band.
Having 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 dif
ferent bands, each device gets a larger share of the available WiFi
bandwidth. The computers in Figure 8, A tri-band network has two dedicated 5 GHz
bands on page 57 have a 1,300 Mbps capacity. They share a 5 GHz WiFi band, and each
has a WiFi connection speed of 650 Mbps, compared to 325 Mbps shown in Figure 7,
Dual-band WiFi network with one 5 GHz WiFi band on page 56.
• Smart Connect directs WiFi traf
fic 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 have to share your WiFi connection with as many devices.
