I think its link to the part 15 PDF on the fcc.gov site is wrong though - here's a (currently) good one: http://www.gpo.gov/fdsys/pkg/CFR-2009-title47-vol1/pdf/CFR-2009-title47-vol1-part15.pdf An index for all of Title 47: http://wireless.fcc.gov/index.htm?job=rules_and_regulations Some official IEEE specs: 802.11a, revised 2003: http://standards.ieee.org/getieee802/download/802.11a-1999.pdf 802.11n spec, adopted about 10 months ago: http://standards.ieee.org/getieee802/download/802.11n-2009.pdf Note that both of those should take you to a page where you have to choose what type of user you are (e.g. academic/student), then click Accept/Begin. Even IEEE members cannot download specifications for free until at least 6 months after approval (well, Standards Association working group members get the drafts on which they vote), though we do get a discount.
