Walkie Talkies are portable, hand-held communication devices. Their history can be traced back to the Second World War. Different walkie talkies were developed for the various armed forces, though the commercial versions as we know them were introduced after the war.

Walkie Talkies - Features
Walkie talkies are unique in that the half-duplex channel they operate on will only allow one radio to transmit at any time, though there are no limits to the amount that can listen. Instead of a telephone style earpiece, walkie talkies implement a loudspeaker which enables conversations to be heard without holding the unit to your ear. Walkie talkies connect to both other handheld units and to fixed position radio stations. Walkie talkies are usually the shape of a large portable telephone, and have a fixed antenna at the top.

History of the Walkie Talkie
Motorola actually developed the flagship sound transmitter and receiver to be labelled a ‘walkie talkie’. The team involved designed the Motorola SCR-300 with the use of frequency modulation. The flagship walkie talkie, due to its size had to be worn on the back. Not long afterward, during World War 2, Motorola produced the ‘Handie Talkie’ which rather confusingly is what we would now recognise as a ‘Walkie Talkie’. Though its performance was hugely impaired, it became the first handheld device that was self-contained.

Walkie Talkies Nowadays
Walkie talkies are widely used nowadays in both consumer and commercial environments, for example outdoor recreations, business use, military and public safety. As a result, the variety and quality of the units is substancial, from high grade commercial units to kids walkie talkies. With the improvement of technology resulting in smaller components, the walkie talkie housings have also reduced in size. Normally, you’l find the commercial walkie talkies are tougher, in protective cases and limited to a select few frequencies. Consumer walkie talkies on the other hand tend to be smaller, more lightweight and capable of scanning across far more channels within the band. Kids walkie talkies are usually of a lower power and as a result are exempt from radio licencing laws. Although they may look the same as a fully fledged walkie talkie, they are normally lower-tech when compared.
