FDD would lower round trip latency for one thing. Frequency re-use is
still achievable with FDD. For example if two devices on the tower are
listening on the same channel, then neither is talking on that
channel....therefore neither one interferes with the other. You'd still
have to watch out for stations hearing two AP's on the same channel, but
(for example) back to back re-use should be ok with or without sync.
The trouble with FDD in 802.16d was lower throughput. You had to use
smaller channel sizes to get sufficient separation between tx and rx.
In an unlicensed band you could do something like 2.4 tx and 5.x rx. Or
5.1-5.2 for rx and 5.7-5.8 for tx. In those cases you've got a big
enough band to use a whole 20mhz channel.
I don't know why nobody's done it already....there are probably
challenges I don't understand. Or maybe it just costs too much.

Why would you want to run FDD for PTMP? Wouldn't that prevent using
sync for frequency re-use?

If the announced stuff happens (I am not sure with this as UBNT failed

present and past) it will be different than 450m.
What is most interesting to me that they claim it to work TDD or FDD.
Then it will be the first affordable FDD PTMP Platform. This is
nothing 450 can do. If Ubnt will do massive mimo is questionable. They
talked „advanced mimo patterns“ but who knows.
I have learned to see and use what is buyable. Vendor promises are
„might happen“. Seen this with cambium, mikrotik, ubnt, mimosa,
mercurynets, …

LTU should be a PMP-like platform at a lower cost. It should check
lots of boxes. It won't be a 450m, though.

Elevate, as far as I can tell, is designed to provide a non-forklift
migration path to ePMP. I don't see either Elevate or ePMP playing
to the same market is the AirFiber LTU or the 450-derived platforms
(including Medusa).
My best guess from everything I've read and heard is that the AirFiber
LTU is going to live in the spot between the ePMP/802.11 derived
radios and the 450m, both in price and performance.
Put differently: 802.11<ePMP<AirFiber LTU<450i<450m. (Or maybe
switch 450i and Airfiber LTU, or change < to =)

It's called Airfiber LTU the AP will have a SFP port they designed

And working sync obviously from the Motorola guys the win cambium is
having with epmp elevate is going to be very short lived tables about
to turn on cambium in a big way and I think that's why they are
taking a huge risk of getting into legal trouble from UBNT but I
don't think Robert cares as he already knows he won the end game

So, more then a month out and no 450M operator with raving
