Upgrading Airport Card to 802.11ac

Hi,

I have a MacBook Pro 17" Unibody A1297 (EMC 2352) 2.8 GHz (Mid 2010).

I have CenturyLink Fiber Gigabit service to my house and would like to upgrade my Airport Extreme card to 802.11ac to improve my speed. Is this possible?

If so, can you recommend the proper part that I would need?

Thanks
