Note about this update, while I do not have access to the release notes, I do know one thing about this update and this comes from my experience and talking to Mimosa earlier this week.

I had a sector automagically switch to a 6 GHz channel when I made a mistake in channel selection earlier this week. When I asked Mimosa they said 2.5.1 would be out soon to fix this issue. If you do not update to 2.5.1 soon I would recommend adding 5.926 GHz through 6.200 GHz as excluded channels on ALL United States Licensed 5 GHz Radios in your network, This could get you into a lot of hot water with the FCC and there are many private Licensed PTP links in that spectrum that, if you mess with, they will come at you with lawyers and cost you lots of money. We have several 6 GHz PTP Links and if anyone messed with us we would come after them, I can understand unintentional mistakes, but many companies will not when you effect their bottom line and their service adversely. TLDR:DO NOT OPERATE ANY MIMOSA EQUIPMENT IN THE 6 GHz SPECTRUM IN THE UNITED STATES.

A5 stuff:

  • Blocked use of 5.925 GHz through 6.200 GHz by the A5. (This is all I know about ATM)

As far as I know, that’s the only change with 2.5.1

Correct, that is the only change between 2.5.0 and 2.5.1. Please use the 2.5.0 release notes with 2.5.1. Thanks!

Awwwe, No new notes! WHAT AM I GOING TO DO WITH MYSELF!!11!!!

Coo coo cachoo! Thanks guys.

why not just update the notes and version on the pages.

Does this change affect other countries than the US? Poland Licensed in my case, and I pay our regulatory authority to use part of the 6GHz band (in fact, the advertised frequency range “up to 6200MHz” was the specific reason why I started with Mimosa A5/C5 in the first place, as other low cost radios could only work up to 6100).
BTW, after upgrade from to 2.5.0 I see the TX power of the A5 reduced from 30 to 24 dBm - is the power really reduced by 6dB, or just reduced displayed values to better match true TX power? And, still no 75/25 split.

Hi @Marek2,

This change was only for US Licensed mode. Also the TX power wasn’t reduced, it’s just be changed to show TX power per port – to match true TX power.

75/25 is still coming, but probably in the next few months.

@Joshua2, first off, I don’t work for Mimosa, one of my jobs at my company is to summarize patch notes for various manufacturers and send them to my coworkers. Mimosa did one or two notifications a while ago about their updates, but stopped, so I decided I would do my own. It doesn’t take much extra time for me to copy and paste what I already get paid to do.

Secondly, yes, I kinda would like a patch-notes, but @DustinS has been pretty busy so that it hasn’t come out yet is understandable. Especially because it is so small.

Where do i download the latest firmware and can i go from straight to 2.5.1 ?

login to your Mimosa Cloud account, you will find downloads under “Manage” >> “Update Firmware” (In the Left Menu) >> “Download Firmware” (A tab to the right of the first tab open that says “Update Device Firmware”

Going from straight to 2.5.1, I think it would be fine. I am pretty sure all of the latest firmware updates are good to go if the firmware is above 2.0.0
