What is a walkie talkie

A walkie talkie is a two way radio transceiver that is handheld and portable. Its development has been credited to a large number of developers, first among them Donald L. Hings, Alfred J Gross and an engineer at the Galvin Manufacturing Company. (There changed name and became Motorola, as it is still today). Characteristics of Walkie talkies are that they look like typical handset with a built-in speaker at one end and a microphone at the other end, they may be slightly larger than normal, but may be less if the speaker also acts as a microphone. They are a single device with antenna mounted on top of walkie talkie. There is usually a push-to-talk button that starts the transmission and it is a special feature of these devices. Talkie talkies are meant to speak between two or more parties, each having their own device. These handheld transceivers can be used to communicate between each other, or a vehicle-mounted receiver or base stations. They can only be used in a limited area, as the range is usually few kilometers. The frequency range is usually 446.0-446.1 MHz, with eight channels allocated for voice usage, each with a bandwidth of 12.5 kHz.

History

Walkie talkie has its roots in World War II and the decade before. Early in the development of radio technology, there was a lot of energy and innovation and new ideas about how radio technology could change communication. The handheld portable two way transceiver, which became known as a walkie talkie, was the perfect example of this. Within the cell phone, walkie talkie changed the communication dynamics to something where you could keep in touch with someone who is far away without sacrificing his mobility, making it the perfect tool when communicating over distance but at the same time being flexible about his own location. Triumph took place during World War II, but the difficult question has always been who developed this wonderful tool? As mentioned, there are many possibilities. It is true that it was an idea many had about the same time. However, the person with the strongest argument for inventing walkie talkie may be Donald L. Hings, an employee of a Canadian mining company. It invented the device as a way to help workers in remote areas communicate with each other, perhaps as early as 1937, his invention was in use. It should be mentioned that he called this a pack-set and not walkie talkie. The term was first used later. About the same time, the Canadian-American inventor Alfred J Gross invented a portable two-way radio in 1938 and gave that idea to the American As said, Galvin Manufacturing Company (Motorola), with their famous invention for the car radio. The developed "handie talkie" SCR-536 in 1940 and since developed the two-way FM band radio technology. (it was not just a portable device as it weighed over 15kg in one where it shined most in World War II. The military advantage was described in an article in Toronto in 1943 as follows: For infantry, walkie talkie is like giving an American football-team quarterback. Before walkie talkie battalions in today's fast moving warfare, it would often be like a football team without a signaling quarterback due to inadequate or broken communication lines. Today with walkie talkie, the battalion headquarters can lead units across large stretches of the front of the game as a quarterback sends its team on and in addition, the headquarters will constantly know what is developing in each area of ​​operations. The talk of Walker's existence in the 1940s can be considered to have saved countless lives. And they are still using it Today of our modern military and you can hardly imagine changing within the next decades. Of course, it's only in the military who has the benefit and pleasure of this invention, no, it is perhaps strange here in the civilian world that walkie talkie shows her splendor.

Walkie talkie and the military

Where it shined most was in World War II. The military advantage was described in an article in Toronto in 1943 as follows: For infantry, walkie-talkie is like giving an American football team a quarterback. Before walkie talkie, battalions in today's fast moving warfare, it would often be like a football team without a signaling quarterback due to inadequate or broken communication lines. Today with walkie talkie, the battalion headquarters can lead units across large stretches of the front of the camp, like a quarterback sends its team on, and in addition, the headquarters will constantly know what is evolving in each area of ​​operations. Walker's existence in the 1940s can be considered to have saved countless lives. And they are still used today by our modern military and you can hardly imagine changing within the next decades. Of course, it's only in the military that benefits and delight in this invention, no, maybe it's strange Here in the civilian world that Walkie Talkie shows her splendor.

Walkie talkies in no military use

They were quickly associated with the use of toys. What happened in America was that government had to step in and protect children's rights to use walkie talkies as toys. This happened in 1977 and the FCC increased the official frequency of unregistered toy walkie talkies from 27 MHz to 49 MHz, an idea that had existed from around 1967 and that was because these frequencies were exaggerated by the more powerful CB radios. But walkie talkier is widely used today in many environments where portable radio communication is necessary, including in business on, for example, construction sites. In the field of public security such as police and fire services, outdoor activities and more. Walkie talkier comes in many price ranges from cheap analogue devices sold as toys to more robust units that are waterproof or self-secure, primarily designed for use in heavy industry and fisheries. Walkie-talkies, thanks to increasing use of miniature electronics, can be made very small, with some personal two-way UHF radio models that are less than one game card. Most countries allow the sale of walkie-talkies for at least business, marine communication, and some limited personal applications. Commercial and consumer equipment differs, as said, in many ways, but primarily commercial goods are resistant and only access to a specific number of frequencies programmed. Consumer equipment is smaller and allows access to channels within the specified band of frequencies. There are, as mentioned, a variety of different walkie talkies and they can bring joy to both old and young. One can see our range is consumer walkie talkies perfect for fun and buggy for the little ones, but indeed, only use in outdoor life.
