With three-stream 802.11ac technology, the AirPort Extreme Base Station takes Wi-Fi speeds over the top. You can reach data rates of up to 1.3 Gbps - triple the previous 802.11n standard. Which means up to three times faster Wi-Fi. 2 You also get double the channel bandwidth, with 80 MHz-wide channels providing more room for more data to flow faster than ever. And if you have 802.11 a/b/g/n devices, AirPort Extreme maximizes that connection as well. What you do with all that extra speed is up to you.
AirPort Extreme features simultaneous dual-band 802.11ac Wi-Fi. That means it transmits at both the 2.4 GHz and 5 GHz frequencies at the same time. So no matter which band your wireless devices use, they will automatically connect to the best available band for the fastest possible performance.
