People often tend to consider walkie-talkies and two-way radios to be interchangeable with one another. However, if you want to be specific about it, these two are different from one another. A two-way radio works by receiving and sending, which is why it’s called a two-way radio and also why it has another name, which is the transceiver.
Now, this definition is where the confusion comes in because a walkie-talkie is simply a portable version of two-way radio. You can walk around and use a walkie-talkie, hence its name, but it has limits in distance too. Technically, a walkie-talkie is a two-way radio, but not all the two-way radios are portable so they’re not all walkie-talkies.
