Application of Two Way Radio

How Two Way Radio work?

Walkie talkies are considered to be simplex two-way radios. There are usually two different types of two-way radios, simplex and duplex. Simplex two-way radios are classified as radios that use one channel to transmit information. This means that at any time, only one person in the conversation can speak and be heard. The most common two-way radio is a handheld radio or walkie talkie, which usually has a ‘push to talk’ button to initiate transmission from one unit to another. At the same time, duplex two-way radio uses two different radio frequencies at the same time, creating the ability to conduct continuous conversations. A common example of this type of two-way radio is a product that many people use in their daily lives, such as cordless phones or cellular phones
