The WiFi family of standards (IEEE 802.11) is used for Wireless Local Area Networks (WLANs). Its first ver- sion from 1997 has been extended by many amandments such as IEEE 802.11n-2009 (now part of IEEE 802.11- 2012). 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 cor- rection as minimum requirement. LDPC codes are op- tional but because of their superiority over convolutional codes they are widely used today. The Creonic IEEE 802.11 LDPC decoder is a high per- formance implementation for WLAN and further applica- tions and supports all LDPC codes as defined by the standard.
