my expensive ham radio won't quite get up to 5G but it will do 10 watts of power on 1.296 GHz which is lol it's incredibly inefficient and difficult to generate microwave RF this thing is a blowtorch if i want to just willfully interfere with people i have a 600 milliwatt ubiquiti bullet i can use to make 2.4ghz unusable for a half mile radius

magnetrons are a very coarse firehose of RF on a general range of frequencies. if you want to transmit actual information you need a really accurate oscillator driving everything, which is why my good microwave rig has a 10.000000 MHz clock input meant to be strapped to a GPS-disciplined clock source

the stock stability is 0.5 PPM which sounds great until you realize at 1296 MHz that means you have 650 hertz of wiggle in either direction, which is absolutely intolerable for precise modes when you're bouncing RF off the moon or whatever. strap a GPSDO to it and you're locked down to 10, 20 hertz. much better!

cell base stations all use GPS for clock sync which is why hams will calibrate their radios to LTE carrier signals. it's not really easy to get tighter sync than that. GPS is amazing.

Sagebrush posted:are there ANY actual advantages to all this 5g poo poo (higher data rate to consumer devices doesn't count, at this point that's like selling 8k tvs) or is it entirely a marketing thing to get people to buy new phones the current installation of law enforcement radios are the last ones that will not be on 5G. We will be moving to a shared network where cops can commandeer tower capacity for whatever they want, cutting off ordinary people from access. That has huge benefits in a protest situation.

Sagebrush posted:what's the right kind of portable radio to carry in a protest situation you either run $1200 encrypted motorola radios or $25 baofengs. Both have their strengths and weaknesses.
