I was helping a friend set up a Verizon femtocell way out in the boonies

And in the debugging process I noticed that new WISP radios nowadays have a
GPS light when I checked the signal strength indicators on the transceiver.

My rooftop radios do NOT have GPS - what is the use of GPS in WISP today?

Seems like precise timing for TDMA slot alignment to avoid collisions, etc.

"GPS for Superior Co-Location Performance Precise GPS frame
synchronization enable co-located Rocket Prism 5AC Gen 2 radios to
transmit and receive data without interfering with each other, allowing for
better frequency reuse and increased network stability."

"Ubiquiti's HDD mode combined with the GPS Sync technology allows all
co-located radios to simultaneously transmit. This is extremely
effective in minimizing co-location interference."

Clearly you need a KS-15676 in your collection:
