Why do they put GPS in new AC WISP radios nowadays?

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."
