A walkie-talkie is a portable device that helps you communicate during emergency situations with the availability of different channels. It offers seamless communication in the absence of a network. This portable communication equipment works on the push-to-talk technology, which allows only one person to talk at a time. There are many benefits of walkie-talkies and having one at your disposal can offer you an efficient and affordable way of communication.
How Do Walkie Talkies Work
Radio signals
The push to talk button helps you communicate by converting your voice to radio signals in long-range walkie-talkies. These radio signals are part of the electromagnetic spectrum and travel at the speed of light to reach the channel towards which the signal has been aimed.
In some situations, you might also experience interference in the communication which happens because too many frequencies can be communicated at once. The message becomes difficult to pass through in such situations. Walkie-talkies have improved with the advancement in technology now. You can also transmit messages seamlessly through jammed airways with many advanced models.
FRS/GMRS radios
Family radio service and general mobile radio service are the two frequencies that have been allotted for public use and operate at 460 MHz in wireless walkie-talkies. FRS operates at low power and works well for short-range communication. GMRS on the other hand is more powerful and offers long-range communication. The message also transmits farther using repeaters. The BaoFeng BF-F8HP has got positive reviews for its VHF range of 136-174 MHz(Rx/Tx) and UHF range of 400-520 MHz(Rx/Tx).
CTCSS/DCS
The continuous-tone code squelch system and digital coded squelch technologies are used in industrial walkie-talkies. In these, encoding takes place to eliminate the mixing of voices. Sometimes you might hear a stranger’s voice on the device when you are on the same channel. CTCSS/DCS technology prevents this from happening.
The devices like Winehouse Walkie Talkies are kid's toys that are waterproof and include 3*AA1000mAh batteries. They have got good reviews for Auto-squelch technology that reduces interference.
What Are The Components of Walkie Talkies?

How to Use Walkie Talkies?
A walkie-talkie is a two-way radio communication device that you can use to communicate with your group of friends or mates. It has different frequency bands, called channels. All individuals have to switch to the same channel to be able to communicate with each other. The loudspeaker stays on by default and switches to the microphone when you press the push-to-talk button for speaking. You can give your message by pressing the PTT button and other members in the same frequency channel will get the message.
This device is half-duplex which means only one individual can speak at once. This is because a single channel sends single only in one direction. Other members will have to wait for your message to get over first. This is not the case in full-duplex devices like the telephone, where you can speak and listen at the same time.
How Long Do Walkie Talkies Last?
Most walkie-talkies last for about 18 to 24 months with their batteries losing their charge. The rechargeable batteries can last for up to 12 hours on a single charge.
