Netgear R7900 - Nighthawk X6—AC3000 Tri-Band WiFi Gigabit Router 사용자 설명서

Tri-band WiFi delivers 3.0 Gbps combined WiFi speeds through three dedicated 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.

Smart Connect intelligently selects the best WiFi band for each dual-band device to optimize 
connection speed and performance based on that device’s speed and performance. The 
router automatically manages your WiFi connections, performing load balancing across the 
two 5 GHz radios. This additional WiFi bandwidth combined with the intelligence to segregate 
traffic based on WiFi speed and load balancing provides the best performance for multiple 
wireless devices in the home.

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 devices that are 
downloading data at the same time. So if you are watching a Netflix movie 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. Even 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 but the
