On the same tower we have 10 APs-
All are with GPS sync
There are no rules!
It loses GPS sync even though it hears enough satellites with a good signal.
Sometimes one, sometimes three never all.
Setting GPS sync maintenance to maximum time may solve the problem on two APs.
On ten devices, some of which are in the shade and some in the sun, it doesn’t work very well. Due to the difference in temperature, the oscillators start to slide.
An internal oscillator with 10 ppm can hold it for a few minutes, up to half an hour.
After that, the performance on a device that has lost sync due to the temperature slip of the oscillator begins to fall sharply, and causes a problem for the AP and also for others.
We tried all the logical positions of the external GPS antenna. The problem still exists.
Two antennas next to each other one maintains GPS for ubiquiti Airfiber (GPS signal is three years j constant)
Second on the Cambium AP 2000 (record 3 months with GPS holding in one piece).
Scenario…
He calls the client and says I don’t have internet or network service.
We look at its primary AP lost GPS sync, catastrophe and secondary also.
Even worse disaster second secondary ordered a huge number of clients once and 120.
That doesn’t work at all then.
I look at the other APs on the same tower, they hear the satellites and the GPS constantan.
Reboot, firmware change restore it and it works.
Then wait for the time when the clients are asleep.
All those clients who migrated to another AP manually one by one to return to the preferred ap, it’s a lot of time.
Of course everyone is asleep but their frustrations over the disconnection have already poured out on me.
Then a similar scenario is waiting for the AP, which worked ok this time.
And why all this?
The magic solution in writing a firmware that should be done would solve a lot of things.
-
To take a closer look at that GPS sync.
-
To add an option in the radio settings: “In so many hours scan the spectrum and search for your primary AP and associate with it” or do it every hour two.
That solves the problem quite a bit.
Perfection would be if it was done like this.
Because all APs on the same tower are an integral part of the same network.
Or dislocated again in the same network are irrelevantly connected one way or another.
scenario.
The AP that returned to the broadcast received GPS or power should be sent over the network identification to other APs. hello here I am.
Other APs forward this to ether subscribers and they know it is primary in function.
Then I could sleep too.
You need to add this as an option that will bring relief not only to me but to many others as well.
We lost patience. It no longer occurs to us to talk on the phone with anyone from the technical support. What is the firmware, what antenna, what do you have nearby, etc.
The problem remained, and every now and then we lose customers due to the loss of GPS sync.
And of course it costs money.
Best regards
