Like a police officer’s handheld radio is able to transmit to another unit let’s say 10 miles away, and he’s able to do that with ease. How is this possible? How come handheld radios that we have access to can’t do that? I know this probably sounds dumb to most of ya’ll but

Police carry around a big heavy radio that weighs 3-6 times what a small phone or radio weighs. They use that weight to get a more powerful signal, like a phone vs a Bluetooth speaker. They also use lower frequencies, which carry farther for the same power, like a boom box vs a water bottle size speaker. To get even farther they network those radios together like a Sonos, so you can hear from everywhere.
