i dont find any docu to this new setting in wireless interface (AP)
installation=outdoor/indoor/any
What is the impact of this setting ?
best regards, RIchard
It has to do with regulatory rules relating to power & usage of transmission frequencies. Indoor regulations are usually different from outdoor.
Been mentioned recently by Tik personnel on this forum.
so should i leave it to “any” or switch to “indoor” … (i only use WLAN indoor) ?
thx, Richard !
If you set it to indoor (and have frequency=auto) your device might use some frequencies which are allowed only for indoor. If you set it to outdoor, your device might use higher power on certain frequencies (or lower, I’m not sure which) … If you leave it to any, then some black magic will do its job.
Wondering if “any” wouldn’t be the worst, as it would need to comply with any conditions, so apply all restrictions…
Edit: Normis clarified below
I use (RB4011iGS+5HacQ2HnD-IN):
2,4GHz G/N, Freq. 2437, 20/40MHz XX, Installation any, Gain 3, regulatory-domain, austria
5GHz A/N/AC, Freq. 5180, 20/40/80MHz XXXX, Installation any, Gain 3, regulatory-domain, austria
So should i go to indoor ? i am confused 
Richard
“any” might indeed be the worst … but then the RB4011 has no idea when Richard is out skiing and when he’s in a Stube having a beer or two with friends so RB should really apply all the worst limits all the time.
I’m confused mkx, do you think he is an athlete or a chain smoking alcoholic. Please make up your mind. 
so switch to indoor ?
Its a flat in the 3rd floor…not a house near the ski slope 
Richard
Richard, surely the flat has some terrace … that might qualify as outdoor
Seriously … these settings are more or less stuff for people who don’t have knowledge to make manual selections. As I already wrote, I suspect that setting affects automatic selection of frequencies … and probably affects max Tx power on some of frequencies. When you set frequency manually, it will prevent from setting it (if it’s illegal to use it in given context) and set Tx power to legally allowed value (which is more or less the case already).
For example: as you’re in Europe, setting it for outdoor will prevent you from using frequencies from 5150 MHz to 5250 MHz (marked as indoor in wikipedia list of channels). I’m not sure if there are some channels that are allowed to use in both indoor and outdoor, but the EIRP limit is different?
MikroTik devices are certified for both, you can use “any”, so more frequencies will be available. Check with local regulations for more details on how you are allowed to operate. Most likely, when using the device outdoors, you should set it to “outdoor”. The command “/interface wireless country-info spain” (for example) will tell you which are the indoor frequencies. This mostly affects the users in European Union.
ok, thx ! all clear now
Richard
Hey @normis, is “any” the most loose setting then, requiring administrator to make sure regulation is not broken, or the most strict one complying with any regulation?
yes that’s right.
Er…?
It was an " or " question.
Did you mean “yes, “any” is the most loose setting”?
setting any will allow all, as not to break existing setups.
