You posted the thread in the wrong section, he moved it to Networking for you

B is old, no one uses it 11 mbps max

 

G is still old, not much is limited to g 54mbps max

 

N is failry new, lots of stuff uses it 450mbps mas(approx)

 

AC is newest in use, 1800mbps(for today) max, most new phones and laptops use it

So there a few reasons you'll want to use AC access points: It allows you to use a wider spectrum, which means the bandwidth increases. 
In order to increase the bandwidth even further, more efficient modulations like QAM256 are used, but since those are more noise-prone, you'll want to use multiple wired access points, on lower transmission power with a min-RSSI for clients configured, with non-overlapping 80mhz-channels configured to ensure you'll have maximum throughput per access point and client. Nowadays access-points can serve multiple streams over multiple antennas in the same wifi band (2.4 ghz (the  crowded, noise legacy-band) or 5ghz (the newer, wider band you want to use)), this feature is called MIMO, multiple-input and multiple-output, in order in increase the speed even further. The newest generation of access point, is able to deliver MIMO to multiple users, called MU-MIMO. 

Smaller AC access points usually provide 2x2MIMO, while enterprise models provide up to 4x4MU-MIMO on up the 160 MHz channels.

This allows you to move multiple gigabits over the air.
