On the ip20 if you add another set of radios(with proper interconnection to the master and calculated spatial diversity) you double your throughput. That’s the mimo function Ceragon sells, don’t know if Cambium its marketing it. SIAE has it in their roadmap

Cause the term MIMO its being used differently by manufacturers of Licensed and Unlicensed Gear: UBNT AF11x its a XPIC full duplex radio, meaning you can use the same channel pair in both polarities (if licensed). You cant use different channels in different polarities -UBNT might call it MIMO because of its traditional marketing for its unlicensed gear Ceragon IP20 and Cambium 820 are a dual RF Core true MIMO radios as you can actually double your Bandwidth by adding a spatial diverse 2nd antenna and radio. For example: You can do XPIC with the same channel pair as the AF11X and then double your throughput by adding another link (with antenna) in the same channel pair in the same path, so you end up with 2 ODUS and 2 antennas per end, installed at a calculated distance in the tower to double your speed. Mimosa its a different radio at its a hdx unit with a pseudo-mimo. It uses the same channel at both ends, using both polarities at the same time. AFAIK you cant operate it in single pol/SISO.

The Mimosa is a very strange duck. Even using 2 channels and 2 polarities, there is no way to actually run it full duplex. The high-latency half duplex is pretty much baked in. IMO, it squanders air bandwidth at the expense of cheapness. And it's highest modulation rate is still only 256QAM.

I'm asking because I guess I'm just ignorant. MIMO = single carrier (is OFDM implied?), dual streams? And XPIC = dual carriers (is single-carrier QAM per channel implied?) and independent streams that are aggregated in hardware, perhaps as simple as a LAG on the internal switch? Or does XPIC add some more magic? So then what is the UBNT AF11X considered? Or the AF5 and 24 for that matter since they're also capable of FDD.

The biggest difference between the two is that the Orion supports XPIC where as the Lynx does not. Keep in mind that either model can be set up for 2+0, but only with the Orion can both radios operate on the same channel. Other than that, the Orion does offer higher TX power (for certain frequencies) compared to the Lynx. However with 6 GHz, the TX frequency for Lynx and Orion are the same. Orion also features SynchE/1588 functionality which is not found on the Lynx. Both models now support buffer size up to 8 MB.
