There's 2 diplexers per side, so that would be 2 channel pairs, right?
2xTx 2xRx? MIMO-FD?

AF11X actually has two internal radios if my understanding of
the platform is correct. It is Full Duplex + MIMO.

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. We had serious trouble trying to even get 256QAM
on a relatively modest distance link.

I will take a crack at it... just to make sure that My
understanding is correct too.
In licensed radio world, the default lingo is as follows:-
A single channel is actually two channels, one
channel is used to Transmit and the other channel is
used to receive.
and each of these channels pair can be either in V
polarity or H polarity (but not mingled).
XPIC is used to describe a radio where you can mount
two radios together, one using the H polarity and the
other using V polarity, but the same channel...
But still only one channel (H + V) is used to transmit
and the other channel is used to Receive. (Thus Full
duplex)
MIMO...., = One Channel, both H & V polarities are
used, and either one can be used for Tx and Rx (thus
half duplex)
AF11x = Traditional Licensed radio... one
channel/polarity for TX and one channel/polarity for RX
Mimosa B11 = Disruptive... a very odd animal... can
be configured as...
Use one channel (both polarities) for TX and one
channel (both polarities) for RX
or ... Use Two Channels,
both polarities in each channel, and use either one to
TX & RX (more like a dual channel MIMO)
AF5 = Uses one channel (both polarities) for Tx
and one channel (both polarities) for RX
AF24 = can be used as
One Channel (Dual Polarities) for TX and one Channel
(Dual Polarities) for RX
or can use the same one channel (dual polarities) for
Tx and Rx.
Hope this is as clear as mud !

What's so much different between XPIC and MIMO?
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.

modulations would be sensitive enough where
the X-pol isolation isn't sufficient?
Okay, a vendor can if they're more technical
than salesy.
I'm not meaning to imply John was salesy.

Hi Ken, the Lynx and Orion are largely
identical. 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.

Jeremy, I’m trying to remember, can you
upgrade that Lynx to 2+0 with a license
key as long as you don’t need XPIC?
Trango doesn’t spell it out very well on
their website, but it looks like the major
differences between Lynx and Orion are
buffer size, XPIC, and maybe the interface
and powering options? So that you could
still double the throughput as long as you
can license a different frequency pair for
the other polarization. And the issue of
the wired interface speed.

I don't know who has the biggest or best,
but my 6GHz Trango Apex Lynx has been rock
solid for going on four years now. It
does 700Mbps FDX. I believe that the
Trango Orion has XPIC up to 1.5Gbps in a
56Mhz channel.

Well you can only use 60MHz
channels max. That helps make
it more competitive.
6GHz most likely precludes
higher modulations… you just
won’t have the link budget.
Also depends if you’re going
all outdoor or
split-mount/all-indoor.
I’d be shocked if there is a
winner here – I’d go with the
solution your most comfortable
with.
My guess is you will end up
with Ceragon/Cambium or SIAE.
DragonWave Harmony Advanced is
certainly worth a look,
although I’m not sure about
6GHz availability since it
just started shipping.
Chuck feel free to contact me
offlist and we could look at
some things.
