What is it?

Wireless 802.11.x is the Wireless standard to how two wireless devices use radio waves to communicate with one another. 

Common Types of 802.11.x

802.11.n

Wireless Standard with a maximum speed of around 900mbps and capable of dual band wireless both 2.4 GHz and 5 GHz frequencies.

802.11ac (latest)

Wireless standard with a maximum speed of around 1300mbps and support for dual band wireless of both 2.4 GHz and 5 GHz frequencies.

Why Have Dual Band Wireless?

A lot of common routers nowadays feature dual band capabilities with both 2.4 GHz and 5 GHz. This is aimed at reducing interference, as a lot of electronic devices use 2.4 GHz bands such as microwaves, wireless keyboards and mouse, radios, mobile phones and tablets, making the frequency congested and slower. 5 GHz on the hand is used by fewer devices and has a greater speed due a shorter wavelength. However, this does decrease the range capabilities of 5 GHz.

Dual Band gives devices a mix, when in short range it can connect to faster 5 GHz signals while in long range it can connect to slower but more reliable 2.4 GHz connections.
