Let's not confuse "borrowing from fiction" with "predicting the future."
Star Trek Communicators need no tel-com infrastructure to talk locally, to the other side of a planet or to a ship in orbit. They have perfect full-duplex 'speaker phones' that can be heard over and through loud background noise, and can instantly establish a private link with one party or a group of people.
The ONLY thing they have in common with real cell phones is that the flip design of some cells was inspired by them. Might as well say that Star Trek predicted the travel shaving mirror, because I have one them that flips open, too.
The Tazer, similarly, was named to sound like the Star Trek phaser, but it has nothing else in common with the technology.
