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

    Why do they put GPS in new AC WISP radios nowadays?
    <https://i.postimg.cc/dtFnFCrX/speedtest26.jpg> WISP AC PRISM uses GPS

    I was helping a friend set up a Verizon femtocell way out in the boonies
    <https://i.postimg.cc/x17ChVzf/speedtest25.jpg> Verizon femtocell setup

    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."
