Re: [Cambium-users] ePMP 2000 GPS not working after firmware upgrade

[Gabriel Rincon]

Hello everyone.

I had a GpS doing the same thing on a epmp 1000 and I replaced the external gps 
with another one and it came back up.

Where can I get the firmware fir the GPS?

Re: [Cambium-users] ePMP 2000 GPS not working after firmware upgrade

[George Skorup]

Hmm. Yeah, I'd open a ticket with Cambium and let them poke around in it 
and possibly RMA. If it was a bad receiver flash, maybe they can recover it.

[George Skorup]

This looks like the classic issue where the GPS is locked up, which is 
obvious because it's not even seeing the receiver version/info. 
Power-cycle the radio and see if the GPS comes back. If it does, then it 
should say if an update is needed. If it's 3.20_8174, it needs 5.1_8174. 
It's just a GlobalTop GNSS and I imagine Cambium has been working with 
them to resolve the lockups. In fact, read the 3.5.1 release notes where 
it talks about the GPS update to address the lockups. The GPS firmware 
is in the same 3.5.1 release package and you just upload that for a GPS 
update. The GPS firmware is NOT updated when you upgrade the radio 
software. It's a second manual process. The 2k's all have the 
GPS+GLONASS GNSS and are much more reliable. Could very well be a h/w 
issue though, but try the power-cycle first.


I have APs not even using the external puck and they're tracking 10+ 
sats just fine. Primary sync is a PacketFlux injector. Remember, the 
receiver itself inside the case has an internal antenna.

[Jason Wilson]

What version of GPS firmware do you see?  Monitor > GPS Status?  Should be 
reading AXN_5.1._8174

Just grasping at straws.

Re: [Cambium-users] Cambium 900i Performance

[George Skorup]

Back when the 900 450 first started shipping, we discovered a couple bad 
SMs. Linktests were in the dirt no matter what. I don't remember if the 
modulations were always low or not. I'm thinking everything looked 
normal which was why we were so confused. But we put another SM in place 
and it went from something like 4Mbps aggregate to over 20. And repeated 
this at a couple locations. So we set those aside and moved on.


As others have said, what do linktests look like? And what about uplink 
and downlink modulations? What are the power levels? Hotter than -40dBm 
is too much.


My question would be, why are you using 900 for LOS and/or extremely 
short range? I'd put up an ePMP 2k on an omni and call it done.


Also keep in mind that the 900 450 SMs do NOT have the filtering that 
the 450i AP does. They're just that, a standard 450 SM. So if you're 
running zero guard band on your cluster, a really close SM could 
definitely be seeing adjacent channel interference.

We have a problem with 900PMP450i.  We have 4 APs on a tower.  We have 
a customer that is very near (1/10 mile) with clean LOS.  But for some 
reason, the customer can’t get any speed.   We speculated that perhaps 
the SM was seeing too much signal from different APs?   We’ve tried 
locking the SM down by frequency to no avail.  Note; all APs on the 
tower have the same color code.  Note; this is actually happening with 
two different customers each connected to different towers not in 
proximity with each other.


Any theories?

Re: [Cambium-users] ePMP 2000 GPS not working after firmware upgrade

[can...@believewireless.net]

​We've had issues at sites with high ~900MHz interference. If you are using
the new 2k sectors, you can run the GPS
cable in the channel on the side of the antenna with the puck stored in the
top. This has worked for us.​

There was an issue with the previous version of GPS antennas, that came with 
early EPMP1000's.  If the GPS antennas you are using are the ones that came 
with an E2K then you should have the newer model though.  In any case way back 
when there was an issue that the old antennas had in high noise environments.  
We experienced that first hand.  We haven't see the issue since replacing the 
GPS antennas though.  I think we still have the holdover timer set pretty high 
though which might help you in a pinch until a real resolution is found.

Re: [Cambium-users] ePMP 2000 GPS not working after firmware upgrade

[Kristian Hoffmann]

I recall that the newer pucks helped some, but weren't the final fix.  
And yes, we set the holdover to 5 minutes now, so thanks for bringing 
that up.

There was an issue with the previous version of GPS antennas, that

ones that came with an E2K then you should have the newer model 
though.  In any case way back when there was an issue that the old 
antennas had in high noise environments.  We experienced that first 
hand.  We haven't see the issue since replacing the GPS antennas 
though.  I think we still have the holdover timer set pretty high 
though which might help you in a pinch until a real resolution is found.

Re: [Cambium-users] ePMP 2000 GPS not working after firmware upgrade

[Chadwick Wachs]

We fought this for months with a couple ePMP 1000 APs. We changed out 
pucks, tried GLONASS vs old style pucks, changed APs, tried firmware, 
etc. Nothing solved it until we shielded the cable between the puck and 
the AP. Once we put that in a conduit (for as far as we could) the 
problem you describe stopped.  One of these was on our tower with lots 
of FM, AM, UHF. We chocked that up to RF interference (our Mimosa B5 
can't grab GPS either). The other AP was on a mini-pop on a residential 
house with no other RF interference around that we could discover. But, 
as soon as both APs had their GPS cables shielded, problem never returned.

[Cambium-users] Cambium 900i Performance

[Phil Lambert]

We have a problem with 900PMP450i.  We have 4 APs on a tower.  We have a 
customer that is very near (1/10 mile) with clean LOS.  But for some reason, 
the customer can't get any speed.   We speculated that perhaps the SM was 
seeing too much signal from different APs?   We've tried locking the SM down by 
frequency to no avail.  Note; all APs on the tower have the same color code.  
Note; this is actually happening with two different customers each connected to 
different towers not in proximity with each other.

Any theories?

Regards,
