The WiFi family of standards (IEEE 802.11) is used for Wireless Local Area Networks (WLANs). Its first version from 1997 has been extended by many amandments such as IEEE 802.11n-2009. This amendment was developed in particular for high throughputs of 600 Mbit/s on the air interface. The standard uses convolutional codes for forward error correction as minimum requirement. LDPC codes are optionial within the standard but because of their superiority over convolutional codes they are widely used today. The LDPC codes defined in IEEE 802.11n-2009 are also used in the current draft of IEEE 802.11ac. This draft intends to increase the data rates of the WiFi standard to up to 6.93 Gbit/s.
