10-4
We have done 71mile shot with 4ft dishes spatial diversity with ptp600.
Lots of loss to overcome at that distance and professional dish install
is what it took
to work. Link was 99.9987 @ 10Mbs using 5Ghz. Rain fade did not become
an issue until you couldnt see your hand in front of your face and the
link barely disconnected.
Bottom line goal was accomplished with very little down time at all.
I think I will look at that same shot again and see how much throughput
can now be pushed over that link.

Can one do it with 5ghz, answer is YES, but will it allow you to sleep
well at night day after day for long periods of time... chances are NO....
Whatever you can do with 5ghz, you can do with licensed 6ghz (take
this a bit loosely) yes the costs may be a wee bit different.
FWIW, talk to the folks who are most likely have done something similar.
Cambium
Exalt
and possibly Radwin.
Ceragon (licensed)
These folks have deep roots in working with Telco world, and as such
most likely have done long links over water.
Just my 2 cents worth.

That's interesting. Using multiple frequency and hope ducting
affects only some of them? How many DB loss from the multiplexer?

We did a link from across the bay in Corpus Cristi with
Tsunami 5Ghz radios using 4 ft. Dishes using horizontal
polarity. 5 story building on one side and 120 ft.
Tower at other side. These were 10mbps radios and we got
almost 100% across. All the other links on same roof and
other water as well used vertical polarity and had ducting
issues. With MIMO and all kinds of polarity options I am
sure you can find a solution. Antenna diversity must be
engineered for path and conditions. Where are you trying
to shoot from?

Did SAF try 6GHz? Or did they only try 5GHz?
Seems a 2+0 at 6 would probably work at that
distance.. although seawater is a factor I dunno about

Well here's SAF response:
/My link planning team confirmed SAF does not have
a viable 5GHz radio that can achieve your
objective for this path./
Trango:
/rough calculation suggests that even using space
diversity will yield a 3 - 4 'nines' link
(predicted reliability) at around 200Mbps FDX.
The use of space diversity will also add
considerably to the cost (a complete link might be
upwards of $50K)./
I'll ask SIAE...

SIAE AlfoPlus2 6 GHz 1024QAM dual polarity
link. Or two pairs of alfoplus1 1024qam
(single polarity) radios running in parallel,
opposite polarities, equal OSPF cost between
routers.
Or Trango's 1024QAM 6GHz radios.
Why not SAF? I thought there was a 6 GHz
version of the Integra now.

Hello everyone,
What would you guys use for a 60 miles PTP
link? 400Mbps. Oh and it's over
seawater... 20k$ budget.
SAF, Trango both said sorry, can't do.
Mimosa B5C with space diversity and 3k$ maybe.
We do have a working AF5x with a 34dbi
dish doing 150Mbps aggregate.
The link gets bad sometimes because of
ducting/reflection.
How could I use two parabolics dish on
different polarity with the AF5x for space
diversity? Splitter?
Should a B5C perform better or worse ?
