Contention-free pollable (CF-Pollable) is a state of operation for wireless networking nodes. The condition is saying that the node is able to use the Point Coordination Function, as opposed to the Distributed Coordination Function, within a wireless LAN.

A device that is able to use point coordination function is one that is able to participate in a method to provide limited Quality of service (for time sensitive data) within the network.{{cite web|title=Point Coordination Function (PCF)|url=http://www.wireless-center.net/Building-Wireless/2768.html|publisher=wireless-center.net|accessdate=2008-02-16|archive-url=https://web.archive.org/web/20090206233942/http://www.wireless-center.net/Building-Wireless/2768.html|archive-date=2009-02-06|url-status=dead}}{{cite web|title=802.11 Medium Access Methods|url=http://www.wi-fiplanet.com/tutorials/article.php/1548381|publisher=wi-fiplanet.com|accessdate=2008-02-16|archive-url=https://web.archive.org/web/20061111215717/http://www.wi-fiplanet.com/tutorials/article.php/1548381|archive-date=2006-11-11|url-status=dead}}
