Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

Does anyone know what type of forward error correction coding is used in 802.11g?
At 54 Mbps, the 802.11g standards documents states a 3/4 coding rate.
Where can I get more information on the coding using for 802.11g? Is it implementation (chipset) specific?
Thanks for any information!

It's a normal convoluational code at 1/2 rate. other rates are achieved by puncturing data. You can check the 802.11 standards or any digital communication text books for details. The encoder is standard and the decoder is implementation specific.
