===Regulatory domains and legal compliance===
IEEE uses the phrase ''regdomain'' to refer to a legal regulatory region. Different countries define different levels of allowable transmitter power, time that a channel can be occupied, and different available channels.<ref>{{cite web|url=https://standards.ieee.org/standard/802_11-2007.html|archive-url=https://web.archive.org/web/20180915002138/https://standards.ieee.org/standard/802_11-2007.html|url-status=dead|archive-date=15 September 2018|title=IEEE Standard 802.11-2007|page=531}}</ref> Domain codes are specified for the United States, Canada, [[ETSI|ETSI (Europe)]], Spain, France, Japan, and China.

Most [[Wi-Fi|Wi-Fi certified]] devices default to ''regdomain'' 0, which means [[least common denominator]] settings, i.e., the device will not transmit at a power above the allowable power in any nation, nor will it use frequencies that are not permitted in any nation.{{citation needed|date=November 2011}}<!-- is this even possible? No ''regdomain'' 0 behavior shows up in 802.11-2007 that I can find -->

The ''regdomain'' setting is often made difficult or impossible to change so that the end-users do not conflict with local regulatory agencies such as the United States' [[Federal Communications Commission]].{{citation needed|date=January 2021}}
