Walkie talkies are very commonly used for two-point communication. Half duplex channels allow only one radio to transmit at a point in time and the other would only have to listen. Communication is only possible in one direction.
They have built-in speakers and therefore do not need to have a separate earpiece like a phone to hold to your ear.
Portable units are similar to box radios but are equipped with an antenna and both units connect to radio stations that transmit and receive messages from a fixed point or range.
Credit for inventing the first radio transmitter and receiver goes to Motorola. Motorola created and coined the word ‘walkie talkie’ and the model was called the Motorola SCR-300 which was based on frequency modulation. This version was a backpack mounted version.
It was during World War II that Motorola produced the ‘Handi Talkie’, the oldest version of the modern ‘walkie talkie’. was available in the industry.
Today, you get a large number of ‘walkie talkie’ models and varieties that are available to use for different purposes. The prices, as well as the range and quality of the devices vary according to their use. These are used today in a variety of applications including the defense sector, outdoor recreation, various businesses, as well as public crowd management and security agencies.
With the improvement of technology, ‘walkie-talkies’ have also become more sophisticated, more compact and easier to use. Commercial ‘walkie-talkies’ tend to be much more studious, larger devices with protective casing and operate on limited but clear frequencies. On the other hand, personal and individual sets tend to be more elegant, compact and lightweight and can operate on many channels that are available within the band, but tend to lack clarity.
You also get ‘walkie-talkie’ for kids. These are very basic and minimalistic and low-tech featured units compared to the others. They are not very expensive and do not require a license and operate within a range of only a few meters.
