A la velocitat d'1 Mbps, es transmeten 11 chips de codi per cada bit de dades al codificar amb la seqüència de Barker (10110111000). Cada xip de codi es transmet al medi amb una modulació DBPSK (1 bit per símbol). La mateixa seqüència es fa servir per a 2 Mbps, amb DQPSK, el que permet 2 bits per cada símbol. En comptes de la seqüència de Barker, CCK fa servir una sèrie de codis anomenats Codis Complementaris. Es fan servir 64 vectors complexos (QPSK) per 11 Mbps i 4 per 5.5 Mbps. Per tant, es codifiquen 6 i 2 bits de dades respectivament. En fer servir DQPSK, 2 bits més són utilitzats per modular els símbols. Per tant, per cada 8 (4) bits de dades, en surten 8 de codi per 11 (5,5) Mbps. És a dir, 1 (1/2) bit de dades per chip a 11 Mcps resulta 11 (5,5) Mbps. </p> <div class="mw-heading mw-heading2"><h2 id="Referències"><span id="Refer.C3.A8ncies"></span>Referències</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=IEEE_802.11b&action=edit&section=3" title="Modifica la secció: Referències"><span>modifica</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="reflist {{#if: | references-column-count references-column-count-{{{col}}}" style="list-style-type: decimal;"> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><a href="#cite_ref-1">↑</a></span> <span class="reference-text"><span class="citation" style="font-style:normal">«<a rel="nofollow" class="external text" href="https://web.archive.org/web/20070623173728/http://www.ero.dk/documentation/docs/docfiles.asp?docid=1737">FTA/ETS 300 328 - Documentation files</a>».
