A6 Product Page, Design Tool, Mar2023 and Jan2023 Data Sheet Discrepancy

I’ve noticed on the Mimosa Product page (https://mimosa.co/product/a6) it says the A6 antenna gain is 24dBi but on the current Data Sheet it is listed at 16dBi and in the Design Tool it is listed as 17dBi? Also, the Design Tool will only allow the A6 to be set to a maximum of 24dBm but I have a Data Sheet from January 2023 that says output TX power is 29dBm max? Since writing this I decided to look at the current datasheet on the product page and see the data sheet has changed since I downloaded the data sheet in January and the current one now says 24dBm TX Power with 16dBi Antenna and the one I have from January says 29dBm TX Power and 24dBi antenna. These are very large differences… So now what does the A6 actually have that’s on one of my towers so I know what to expect (Received December 2022)? What’s going on with the changing of advertised product specs?

This is one of my biggest complaints with manufacturers. When they make tons of promises “*in a future firmware update” but after having sold several hundred thousand, they remove those lines from the spec sheets. IE: Ubiquiti LTU removed OFDMA, 100Mhz+ channel sizes, and various other minor features.

Note: I have not seen this from Mimosa to this point but it’s scary when other changes to the spec sheets start taking place.


For sure it is becoming unfairly common place in the WISP industry. UBNT’s LTU scale back of OFDMA and 100MHz channels was a big surprise for us too and subsequently we stopped moving forward with it. I haven’t seen Mimosa do that yet either but unfortunately here we are. I dont think its right but I can somewhat understand an over ambitious software dev team thinking they could bring features to market with firmware overtime. What’s bothering me in this case is the specs advertised that have changed are physical components of the antenna and radio so I’m not understanding how something was advertised with 29dBm output power and 24dBi integrated antenna and has now become 24dBm output radio power with a 16dBi integrated antenna but is the same physical product that was advertised.

The antenna gain is 16dBi + beamforming makes it the 24 you see in the datasheet. Some of that was updated because of confusion. The 29 to 24 thing was a typo that didn’t get noticed by those folks until after it was posted.

Design tool I’ll make sure that’s corrected. Thank you

Thanks for the clarification Dustin. The antenna was my main concern as going from 24dBi to 16dBi was a large decrease but with the explanation of beamforming bringing that to 24dBi I understand now.
