WLAN (Wireless LAN) also called Wifi.



This was the first standard in the 2.4 Ghz spectrum. It featured 13 channels in Europe (11 in the USA and Canada). And had speeds up to 11 Mbit/s.


Again in the 2.4 Ghz frequency this achieved bandwidths up to 54 Mbit/s. The bandwidth used required a footprint of 3 channels so it's logical to use 1, 6 and 11 so that no overlapping occurs.


Achieved speds up to 150 Mbit/s and with bonding 300 Mbit/s. This would ultimately take up 6 channels in the 2.4 Ghz spectrum. Also available in this is 5 Ghz spectrum.


Near gigabit speeds, very new in 2013.
