A WLAN regulatory domain is a set of laws or policies that control a bounded area.
Currently, there are governing bodies in many countries around the world, like: FCC, IC, RED, Japan (TELEC), Korea (KCC), Brazil (ANATEL), SRRC (China), Australia (RCM)
The main limitations depicted by the regulatory domains affect the available frequencies and the maximum RF power.
=== Linux setup ===
=== DWS WiFi device ===
The WiFi module supplier provides the embedded FW and the driver SW for assuring that support the DWS WiFi device are is relesed for good wireless operation for almost all generic WIFI use-cases. '''NOTE:''' during the Certification tests, the regulatory domain setup (frequencies and power) should be verified against the limit and power level for the selected country. ==== Debug ==== To debug the actual settings made by the driver, the user should edit the config file <code>/lib/firmware/wlan/qcom_cfg.ini</code> to enbale the log traces, before the insertion of the driver module. At the start of the file enable the WDA and SME logs:<pre>#Host module debugvosTraceEnableHDD=0vosTraceEnableWDA=255vosTraceEnableWDI=0vosTraceEnableSME=255vosTraceEnablePE=0vosTraceEnableWMA=0vosTraceEnableVOSS=0</pre> This operation will taint the kernel console with many debug messages.
