Kidding right? I think all of our APs are sync over power excepting
PTP450, which only does timing port sync. We've just found sync over
power to be most reliable.

Why even mess with Poe sync?

Forrest,
Cambium has admitted there is a problem with GPS sync over power
dropping for no reason on the ePMP APs with some software versions,
and it is a cross-platform problem. It doesn�t seem to be any worse
on our PacketFlux gear than it is on the LMG CTM-2M � and we only see
this on ePMP, never with PMP 100, 320, 430, or 450. Luckily, we did
deploy the puck antennas on all of those AP�s, and they seem to work
just fine with the built-in sync. Cambium is expecting to fix it in a
future software release.

I'll let others speak to the stability (as a couple already have).
A few months ago there was an issue with a mutual customer of mine
and cambium's which was having sync problems with an epmp radio. To
date, I don't know if the problem was with the epmp, or with the
injector, or with a gps lock, or whatever. I can't say that
sync is a perfect thing - from time to time, gps modules act weird,
injectors don't inject, and AP's don't work right - no matter which
product you have. When sync does bad things, it behaves badly. For
all I know, in this case my product *might* have been at fault. Or
not. It's not important for the rest of the story....
In any case, somehow this problem morphed into a statement that
somehow the SyncInjectors had some sort of systemic issue which lots
of wisps were experiencing. I was not particularly amused by this,
particularly since I had no communication from cambium at all in
relation to this.... After some back and forth with my internal
contact at cambium I was informed that a) that they were tracking
some *potential* issue with external sync (usually with a
syncinjector) on the ePMP and b) that they hadn't had the time to
figure out if it was packetflux-specific or a general issue yet, and
that if they determined it was related to my product they'd contact
me back. So far, no call back, and I haven't heard any more similar
complaints - and I've had interactions with a lot of people who use
this regularly with ePMP with no known issues. I also haven't seen
anything sync-related in the release notes since that time.

General question here. I saw something in the Cambium forum
questioning the reliability of Packet flux Sync Injectors.
If you use them, are your GPS syncs stable and is power output
reliable on the 450 and ePMP gear?
