A WLAN regulatory domain can be defined as a bounded area that is controlled
by a set of laws or policies. Currently, there are governing bodies in many countries around the world.
Many countries follow standard set by FCC, ETSI, Japan, Israel etc.
Please note: While all these countries follow FCC /ETSI rules, the validity period of type approval certifications varies as does the necessity of involving a local representative. In some countries additional requirements that complement FCC rules need to be followed up. For example, Australia follows standards set by FCC and it also follows the standards set by ACMA (The Australian Communications and Media Authority) to meet its standards within the region.

List of countries that follow main regulatory domain. Please note that many of these countries also have their regulatory governing body as shown in the below section.
Note: The regulations of Singapore and Taiwan for wireless LANs are particular to these countries only for operation in the 5 GHz band. Singapore and Taiwan are therefore only regulatory domains for 5 GHz operation; for operation in 2.4 GHz, they fall into the ETSI and FCC domains, respectively.
