What is the difference between "g" and "n"?

What is the difference between “g” and “n”?
There are a number of standards for wireless networks (802.11b, a, g and n). The “n” standard is the latest and fastest of these. The “n” standard distinguishes itself from its predecessor “g” by offering a wireless speed which is up to 12 times faster and a range which is up to 4 times greater.

What is the advantage of n?
Nowadays, wireless networks are not only used to surf the Internet or to send e-mails. With the 802.11n draft 2.0 solutions, users can enjoy unprecedented performance in terms of speed and range for demanding applications, such as streaming HD audio and video, Voice over IP, multiplayer gaming and transferring large quantities of data. “N” meets the demand for faster wireless speeds and delivers impressive performance when, for example, downloading files, viewing videos on YouTube or playing your favourite online games with speeds of up to 300 Mbps.

Why is it so easy?
With “n”, you enjoy unprecedented performance in environments with multiple users and demanding applications. Furthermore, all the Sitecom 300N solutions have “out of the box” protection with the latest WPA2 security standard. Thanks to the OPS function, you can create a wireless network with the press of just one button without the need for a complicated installation procedure.

The 300N solutions are backwards compatible and can be used in combination with 802.11b/g devices.
