These are two-way-radio devices that are portable and handheld and provide for instant wireless communications on a single frequency band by using radio waves.
These devices are vastly used in a variety of businesses and industries where instant and reliable communication is required between staff members. These include construction, manufacturing, or security services, to name a few.
They are also extremely popular for the use in leisure activities such as hiking, camping or skiing.
Basically, two-way radios are devices that can both receive and transmit radio communications. Walkie-Talkies are Two-way-radios that are portable and can be handheld.
In a short answer, yes!
Walkie talkies all support the same standard set of frequencies either GMRS, FRS, or a combination of the two. Therefore, they use the same frequencies, so they are fully compatible with each other.
If we take as a reference a business walkie-talkie operating in normal conditions, the coverage is about 2 km (1 to 1.5 miles).
Walkie-Talkies are basically portable two-way radios therefore then can receive and send radio communications. Each battery-powered device has incorporated a receiver/transmitter and an antenna (for receiving and sending radio waves). It also has a loudspeaker that usually is also used as a microphone when you talk into it and a push to talk button (PTT).
In order to sync two walkie talkies, you must ensure that in both devices the private code numbers are set to the same number. After that is done, you can set both radios to the same channel (most radios have 22 to choose from). You can see in the display what channel your device is on for you to save it.
Walkie talkies transmit through radio waves, so it is only normal that communications aren’t always as clear as if you were talking to the other person face to face. To achieve clear communication, you should speak more slowly, using short, precise phrases and speaking at a slightly higher pitch than normal, pausing when necessary.
There is a standardised code that most people use to facilitate communication using these devices that you should learn.
With walkie talkies, only one person is able to communicate at one time so saying “over” is the way to tell the other person that you have finished talking and that is their turn to speak.
