Hello, Our project team is planning to use hostapd to create a wifi access point at the oilfield, but we've been having questions and concerns related to regulatory compliance, as this will be enterprise use, not personal use. I guess, we weren't able to find clear information on how hostapd deals with the country settings and how the regulatory compliance information is being updated. So far I see at least 4 levels of where the impact can happen: - NIC hardware - supported channels and modes - NIC firmware - Linux drivers (in our case brcmsmac) - Hostapd configuration (uses nl80211 to configure the driver) 1. When we set a country and dot11CountryString, does hostapd use a certain database with current regulatory details for the country and translate to driver commands? 2. Where is this database stored and can we update it if some unusual country decides to change regulations (which happens quite rarely though)? 3. Is it possible that hostapd will report the country as set correctly, but the driver will not accept all of the settings, so resulting frequencies on the NIC will not be compliant? 4. I think, worldwide regulatory domain is set on our NIC by default. Will hostapd always be able to change it using the Country setting? If not, will it impact the regulatory profile? 5. What troubleshooting commands can be helpful to make sure the right profile is applied? (e.g. iw reg get, iw list, etc.) Appreciate any guidance on this topic. Thank you very much.
