This specification has expected multi-station WLAN throughput of at least 1 gigabit per second and a single link throughput of at least 500 megabits per second (500 Mbit/s).
There are two cards to match what is inside your Mac. The Macbook air's have two internal antenna's, that's why we call it a qCard 2 and the MBP 15" Retina's have three antenna's thus qcard 3 Utilizing the same chipset and drivers as the new MacBook Air/Pro model, this new PCIe card can be used to upgrade PCIe Mac models to the newly announced Wi-Fi standard of 802.11ac! The Blue Tooth 4.0 LE are also added and use the same number of internal antenna's as the lattest generation of Mac's with 10.10.x its just plug and play.
All you have to do is take the old AirPort card out and put the new one in. As long as you have an OS of 10.8.4 or greater, your PCIe Mac will recognize it instantly, giving you access to 802.11ac speeds at any compatible wireless access 802.11a,b,g,n,ac
If you are somewhere that does not have a wireless access point in the AC spectrum, don't worry. The QCard is fully backwards compatible, allowing you to connect to any wireless network.
There are two versions of the Qcard: a two port for the MacBook Air and the three port for the MacBook Pro.
