We cannot deny the importance of communication. In every aspect of our life, we communicate with each other. Not only for a long range but also within a specific area, we established various types of communication system. If you look around then you will find out the result.
Almost every person in this world uses at least a mobile phone or another kind of communication device for communicating. Except for mobile phones, there are other communicating device works almost like a mobile phone. You may hear about the walkie takie.
In 1937, the inventor of walkie takie names Donald Hings introduces this device to us. From that time this device gets popular.
It was a great invention at that time for communicating in some specific range and frequency. According to the working process and design, we can say that it is totally a cross of a mobile phone and a radio.
In people, there is some curiosity for this device. They exactly do not know how walkie talkie works. Basically, this device uses for receiving and sending data.
Let’s discuss it in details to know the working process. We can describe it in four basic ways and these are.
- Active status: For working this device perfectly it must be powered and turned on. You may see that many people, especially police talking in walkie talkie. Because it works as a transceiver. There is no connection needed for operating it like electricity because it is totally powered by heavy batteries.
- Transmission: If you are not a user of a walkie talkie then you may do not know about the information transmission system. This transmission system, also known as half duplex. There is some transmission signal is available for working this device. The half duplex used for sending or transmission the signal. This signal uses some specific channel. But there is one condition and that is a only happened at any given time. There is some obstacle will arise if you want to send the message at the same time. So you cannot connect with it. There are two options you will find in a specific time. One is listening and another is talking. But the modern technological advancement is giving more option for a walkie takie. Now you can use multiple channels to avoid the interference which gives you much opportunity to get free space to communicate with others.
- Push Button: In things for this device, making works. Without this device, you cannot communicate with other device. So you need a push button. Most of the user knew this button as PTT (Push to talk transmission). It is also describes press to transmit. This button works in two ways.
- Send signals: To send the radio signal you need to engage with the transmitter. For this, you need the push button. When you are holding the button, then you are engainging the transmitter. Now you will be able to send the radio signal to another device which are ready to receive it. After pushing the button the radio will be quite from receiving other signals which coming through the loud speaker. After talking in the fort of this device, all the words you spoke converted into some signals like radio waves. This wave beamed and search for the destination. The destination should be a prearranged or configured channel.
- Receive signals: If you are a receiver of the radio signal than you do not need to push the button. Because multiple devices can receive the message at the same time. To receive the signal you have to release the button, otherwise, you can’t receive it. After sending the signal you must let the button go. It will release the engaging situation of the device. Then you will be free to hear the signal sending from the other device. The most important thing is you can also receive another message from another unit or device which is in the range in that channel which is available for your work and in online.
- Frequencies: You may know about this thing. A walkie talike do not need any kind of dial button. Because it works on and anyone operates it with frequencies. But you have to keep it in mind while using this device is the range of frequencies. The common frequency range for a walkie talkie is 27 MHz. There are some frequencies also used for this device. These frequencies know as ultra an frequency which is starting from 400 to 500 MHz. For the frequencies, that is used for working band for a walkie talkie not operated by any kind of tower. You can use this device behind any kind of obstacle. Because of the clear signal path this device works smoothly. Science proves that radio wave is an actual part of the electromagnetic spectrum that means it has a great speed to send the signal and it almost equal to the speed of the light which is 300000 km per second. That’s the reason a receiver can receive the wave sent from another walkie talkie receive instantly.
There are another facts also liable for a walkie talkie work and that is given below.
- Distance: May any kind of obstacle cannot hamper the frequencies or signal, but the range or distance can do it. If you are out of the range of a walkie talkie then the frequencies will break. In short, distance this device works perfectly. Most of the walkie talkie woks smoothly in the range of 40 miles. Some works far more, but not far.

Most of the people think that this device going to obsolete within a short time, because there are lots of alternatives are available in the market. But this thing as an old school piece is made for the long run. May be we are going to use this device for the next 20 or 50 years. But the unique mechanism and application make this device immortal to us. Most of the industries and groups are still using this device.
