Update the frequency ranges and power limits according to the current Ecuadorian norm [1],
corrected 5GHz maximum bandwidth since there are no legal restrictions in this subject.
Note: 60GHz channels 1 to 3 are allowed without license for Point-to-Point links but
they aren't for Point-to-Multipoint links so they were omitted in this patch.

It looks like 5150-5250 MHz also requires DFS.

5250-5350 and 5470-5725 MHz require TPC. Since Linux does not support
TPC the power limits need to be reduced by 3 dBm, which puts them at 125
mW.
I also don't see any DFS requirement for 5470-5725 MHz.
Thanks,

Yes, I tried contacting ARCOTEL without success to get a clarification
from them because other countries don't require DFS for 5150-5250 MHz.

Thanks for the heads up, I forgot there was a TPC requirement.

Section 2.1.6 says that users of 5250 - 5350 MHz and 5470 - 5725 MHz
should apply the interference mitigation measures mitigation measures in
Recommendation ITU-R M.1652 to ensure compatible behavior with
radiodetermination systems.
ITU-R M.1652 norm section 1.1 recommends the usage of DFS for
5250 - 5350 MHz and 5470 - 5725 MHz, so I inferred the DFS
requirement for 5470 - 5725 MHz as well.

In the absence of any clarification we should stick with the rules as
documented. The database can always be updated later if it turns out DFS
is not a requirement.

Ah, yes, I missed that.
