How Do Two-Way Radios Work?

Today, two-way handheld two-way radios operate on two frequency bands:

Family Radio Service (FRS) and General Mobile Radio Service (GMRS). People often refer to two-way radios as walkie-talkies. Each radio has a transmitter and receiver to send an accept information. When two people communicate on two-way radios, the voice signals are transmitted as radio waves and then converted back into sound for the recipient’s antenna. This is an instantaneous process and allows two users within a certain radius and using the same radio channel (or frequency) to communicate quickly and easily.
