Walkie-talkies are one of the most favorite childhood toys we loved to play with. There would be hardly anyone from the 1990s who hadn’t used a walkie-talkie in their childhood. The two-way communication back then was like magic and the game was so much exciting.
After the common use of mobile phones, the charm may have died a bit but still, the walkie-talkies are one of the attractive toys and good gadgets to play with your mini-war zone and army uniform and children enjoy it a lot.
Generally, walkie-talkies are used within short distances and don’t require any special equipment and license but due to their application in military and authoritative zones, there are some legalities in their use in certain areas and countries.

How walkie talkies work
Unlike all other radio types, a walkie-talkie is a two-way radio i.e. you can transmit as well as receive through your radio set on a single frequency band. The device was developed in 1930 and back then what makes it so popular was that it was wireless and you can walk and talk with it and thus it was named walkie talkie.
The handset consists of a transmitter and receiver, an antenna, a push-to-talk button, and a loudspeaker. For communicating the handsets are set to be on the same frequency and then one is set to sender while others on receiver mode. When the speaker presses the push to speak button the speech is converted into electromagnetic radiations and transmitted while receiving at the other end where they are again converted into speech.
Only one end can transmit at one time once the sender says over the other one can start talking. The range of walkie-talkies is short and interference can occur between different users so modern systems have multiple channels so that transmitters can send signals on different frequencies.
Allowed frequencies for public use
Different types of walkie-talkies are allowed to use in different countries in certain distance ranges.
- PMR446 is a European standard used in Europe and UK with 8 channels and at 446 MHz frequency and can’t have a range more than 2 mile and 500mwatt transmitting power
- In the US and Canada FRS and GMRS standards are used with 14-22 channels available on frequency 462 and 467 MHz
- In India, these frequency bands are allowed to use on walkie talkies
- 957 MHz to 27.383 MHz (Citizen Use Band)
- 335 MHz (remote controls for cranes)
- 4 GHz to 2.4835 GHz (for WIF, Bluetooth)
All these bands are restricted to be used in specific countries and no two standards are allowed in one country neither you can have inter-country communication on them.
Some countries may have restrictions due to security threats for example you are not allowed to use walkie-talkies in France so you may take proper information and permission before operating one or you might be risking legal implications.
The best walkie-talkies of the year are regularly reviewed by tech websites to bring you the most current and feature-rich examples on the market. Just keep in mind the allowed frequencies in the country you are using the radio.
Walkie-talkies are fun for all gadgets and you can have super fun with your family with these walkie-talkie sets. But to make your fun time safe and free from any kind of legal hassle we have listed the allowed frequencies for public use and the power ranges, keep them in mind and use the sets with care so that you may not get into any trouble.
Is tuning into restricted frequencies can cause legal problems?
Yes, the military or the authorities are keeping an eye on the radio frequencies, and in case they catch your signal on any restricted frequencies they can track you down and you may have to face questioning about your action
How children will know which frequencies to use or not?
Normally the kids’ handsets or general use walkie-talkies are given only the frequencies in the allowed band so there are fewer chances of tuning into unallowed channels.
