Hi,

Do you possibly have ideas how to adjust wireless-regdb package
to support also automotive use cases as described in:
https://www.efis.dk/documents/44659

Best Regards

Let's take 5150 - 5250 MHz as an example. It is ok to use it in in the
Cars if EIRP is limited to 25mW,
These regulations applies to EU countries as well as all the countries
which recognize EU rules.
Currently the only solution is to update db.txt to reflect these
regulations by OEM/Tier 1. There is no
generic solution that would cover various applications (e.g. in
automotive) where Linux kernel is used.

Yes, ok, hmm. No good ideas here.

But DE for example specifies

        (5150 - 5250 @ 80), (100 mW), NO-OUTDOOR, AUTO-BW

now?

Perhaps it might make sense to have the db.txt processed by the (C)
preprocessor, and add something like

#ifdef COMPILE_FOR_CAR
...
#else
...
#endif

and then you can build your own binary for the in-car environment, yet
share the sources with the community?
