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.

Maybe someone else was having an

First I have to find out if there are
channels in this area.
Then I have a passive repeater to deal
with...
Not a simple path to engineer.

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.
