Netgear R8000 - Nighthawk X6—AC3200 Tri-Band WiFi Gigabit Router Manual Do Utilizador

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.

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.

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. The computers in 

73 have a 1,300 Mbps capacity. They share a 5 GHz WiFi band, and each 

72. 

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 have to share your WiFi connection with as many devices.
