Wireless networking is covered by the 802.11 standard. See:
http://en.wikipedia.org/wiki/802.11
For 802.11n specifically, see:
http://en.wikipedia.org/wiki/802.11#802.11n
Currently, the most commonly used are b, g, and n. The differences are roughly:
type . . . typ speed . . . max speed . . . distance
. b . . . . . 4.5 Mb . . . . . . 11 Mb . . . . ~35Meters
. g . . . . . 19 Mb . . . . . . . 54 Mb . . . . ~35Meters
. n . . . . . 74 Mb . . . . . . 248 Mb . . . . ~70Meters
Yes, 'wireless-N' is better than 'g' or 'b', but usually slower than wired.
Note that the 'speeds' are in Mbits per second. Divide by 8 to get approximate MBytes per second. Normal wired network connections run at 10, 100, or 1000 Mb, (100 is currently the most common)
Also note that you never get the max speed (that is shown on the box). The 'typical' speeds in that table are more realistic. Actual speed varies by distance and many other factors.
Usually, devices that support 'n' will also support 'g' and 'b', falling back to those if the device with which it is communicating does not support the faster standard.
Hope this helps.

802.11n (the "geek" name for it) is the next standard in wireless technology. While the rule for it have not officially been accepted, they are standardized enought that 802.11n devices are beginning to appear on the market.
They promise speeds of up 270 mbps (compared to 54 for the current 802.11g). Also a longer range. (about twice the current 300 feet, depending on the gain type used)
If you are purchasing a new router, and the "n" is available, go for it. If you have a working router, I would probably wait 6 months to upgrade it, just in case they make a last minute change to the standard that might reduce the life of the early, pre-release devices.

wireless network is better for mobility and convenience, but it has limited area of coverage, a normal wireless LAN has a speed of 54Mbps, while the wired network has 100Mbps. for speed as of now wired network is better...
High speed wireless router are not yet available commercially..
