I won't even bother replying to the rest.
In other words you got called out on your BS and refuse to back it up. Gotcha. I think you're the kind of person who knows just enough to be dangerous. Case in point:
Some towers, where regulations permit, and where sufficiently high enough to avoid a safety hazard, also use microwave links to nearby central offices.
"Safety hazard"?!? How much power do you think microwave links need? Hint: With good antennas and a clear LOS you can go miles with a power output measured in milliwatts. TV stations broadcast with power levels measured in kilowatts, and people live right next door to the transmitters while suffering no health effects whatsoever. You might want to familiarize yourself with the inverse square law and the basic fundamentals of RF engineering....
BTW, that link you gave the other poster doesn't even mention the word "T1" in any context, never mind validating your absurd claim that they're feeding 4G base stations with T1s.
