A lesson I learned from Ceragon and Telrad both: If they give me a port,
I'm putting a cable in it....even if I don't connect it to anything on
the ground.
It was driven home when Telrad wanted to fix a firmware issue and
requested access through a local management cable which wasn't
connected. A Ceragon IP10 failed one day and the vendor wanted console
access. A hundred extra Cat5's is still cheaper than one extra tower
climb in the rain IMO.
And yeah, the quick config wizard was a godsend. I imagine it must have
saved Cambium a lot of support labor. Hey does the IP20 have that? If
you needed another reason that might be it.

like that, I’m sure they got pressured into the setup wizard by
frustrated customers.
If you do buy a PTP820 and intend to use Inband Management (IBM), talk
first to someone else who has done it. Or at least get it working on
the ground first. If you misunderstand how they do IBM and how they
use VLAN IDs, you can end up carrying a laptop up the tower unless you
have a separate management cable. I made the mistake of leaving the
VLAN ID at 1 which is the default, only to find that a Mikrotik
RB1100ahx4 won’t let you use VLAN 1. You’d think no problema, just
change it. Nope, can’t do that over IBM, need management port
access. Not a big deal unless you only find out after the radio is up
on the tower.

Yes, once you get your first one configured its not bad, I had an
issue as well with the first link.

Support.
One thing about the IP20/PTP820 is that it's not obvious how to
configure it correctly. Plan to spend some time with the manuals
or plan to call support. I put in a ticket to Cambium support and
they set my link up for me and I didn't have to do anything and
never had to touch it since. --and I ended up paying about the
same price as I would have paid Ceragon. I don't know what
Ceragon support is like in general, but when I called them about
an IP10 some years ago and I didn't have a support contract they
wouldn't even provide firmware. I'm sure they're awesome when you
pay them.

PTP820 - why buy from Cambium instead of direct from Ceragon?

56mhz throughput data capacities vs 80mhz throughput data
capacities is a significant factor. Plus can the AF11 do
ACCP (Unless yo use 2 dishes or a custom combiner)? We
had a link recently with only 80mhz channels available on
vertical. Getting to 4096 QAM is not easy on longer links
(Probably anything over 4-5miles) IMO. I am a huge fan
of Ceragon IP/20/Cambium PTP820 very reliable radios with
a great feature set. The only thing they are missing is a
SFP+ port (Which I believe is coming on a new version)

Well, the efficiency isn't quite that bad. at 1024QAM
(they actually do support 2048QAM now too) they can do
somewhere around 350-375Mbps per polarity using a
56mhz channel, which is about the same as what our old
SAF Lumina can do at 256QAM... of course if you figure
that as an 80mhz channel, rather than 56mhz, it's
pretty bad. I'm pretty sure that it doesn't meet the
FCC efficiency requirements at the lowest modulations,
but you'd have to have a pretty poorly engineered link
for that to be a problem.

If I remember right the biggest spectral
efficiency problem with the AF-11x is that it uses
both polarizations yet only gets the throughput of
a single pol link. Could be difficult to license
if you can’t get both polarizations. Good news,
if you’re successful getting the license, you
should be able to modify the license and upgrade
to a true 1.3+ Gbps full duplex radio from SIAE,
Aviat, Cambium, etc. Bad news, if you’re pushing
the distance such that you can’t run 1024QAM or
better most of the time, you may not meet the FCC
minimum spectral efficiency requirement.

Yeah, but the AF11 actually has to use an 80mhz
emission designator, even though it's really only
using 56mhz... so theoretically, if you upgrade
the link to radios that can handle 80mhz, you
shouldn't have any problems licensing it.

You license an emission designatior... not a
channel per se.
When you license 56MHz of spectrum you use the
80MHz channel plan but there isn't 24MHz of
unused spectrum sitting there... it gets used
up pretty quickly for other paths, etc.
So moral of the story... don't do that.

No, that's not allowed. You need to
license two 40MHz channels.
