Is there a User/Harware Manual for the BR1 that mention specifically the BR1 LTEA?
Nope. what do you want to know?
Or rather yes https://download.peplink.com/manual/pepwave_max_firmware_manual-fw8.0.0.pdf page 31
We are starting the process to obtain the “NOM”, or Mexican Homologation certification for the BR1. And the Government test labs, is requesting a user or hardware manual, from the vendor, where it illustrates the LTE and LTEA option or each one characteristics.
Are You. Telling mi that the BR1 MK2 is the BR1 mini LTE-A?
No.
I’m saying the BR1 MK2 is the LTE-A version of the BR1 because your original post said:
First time you’ve mentioned the BR1 Mini - which is obviously a completely different model. The BR1 mini look exactly the same if its the LTE version or the LTE-A version (pg 35):
It does have a different ordering code if you pick the LTE-A version though. Typically in homogenization processes they will accept separate model numbers combined with the more generic user guide / manual.
