Hi,
I am being told by Cambium local support that GPS in ePMP or PMP is for clock synchronization.
QUESTIONS:
1. why not using NTP, if it still not accurate. I'll install local NTP
2. because GPS need extra cost. In what situation is mandatory to use GPS
3. other than clock. what other function of GPS sync
tq
GPS sync and NTP (network time protocol) are two totally different things.
GPS sync provides a common 1pps timing platform for all of your radios to synchronize with each other, which allows an operator or multiple operators to use frequency reuse and/or reduce self interference.
If you are deploying only a few radios at a site, and there's plenty of clean spectrum, then you might not need to use GPS sync.
The NTP client on the radios provides accurate time/date stamps for logs and events generated on the radios.

They are not talking about a clock in the terms of telling time. They mean a clock as in frequency generation and synchronization. NTP is useless for this type of "clock".
