LOL. Guessing radio tech isn't something you're into. Think the name comes from one to one radio communications. 🤷♂️
simplex is sending and recieving on the same frequency. no repeater.
duplex is send on one frequency, recive on second. a repeater reverses the two frequencies. broader reach with less hardware required on the users part.
