Walkie Talkie

A walkie talkie, more properly called a two-way transceiver, is a mobile, two-ways, hand-held radio transmitter. The development of this device during the Second World War was differentially attributed to German engineers, German radio operators and military groups. It first entered active service in the United States after the end of the War. This portable radio served several purposes such as general communication, rescue and wilderness emergency operations, search and rescue, military protocol, and weather monitoring. The use of the walkie talkie had its drawbacks and limitations, such as limited data transfer capability, requiring the coordination of multiple channels and signal interference by other wireless devices.

The Walkie Talkie: Developing the Ultimate Radio Telecommunication System Based on microwaves First, the basic function of the walkie talkie was to be an automatic communication device between a source and receiver, either by using a transmitting device such as a base station or by using a receiving device such as an antenna, or by using a directional coupler, or by using a combination of both. In the earliest designs, the transmitter was often coupled directly to the speaker thus making a need for a directional coupler. The use of a directional coupler meant that the time needed to send a transmitted signal was longer than those required by earlier designs.

A Walkie Talkie as a Means of Wireless Communication Relay radio systems were also developed during the war years. These types of radios allowed the user to talk and use data in the same unit, much like a telephone. This was particularly useful in areas where both radio services and telephone lines were scarce. Base stations could receive and send signals to a central area where a walkie talkie could then receive and transmit the data. In these early systems, the distance that a signal could travel was limited by the power of the signal being used.

Two-Way Walkie Talkies The basic construction of a two way radio was almost identical to that of a walkie talkie. However, in order to use a two-way speaker system and transmitter, a separate line was required. Thus, the first two-ways were limited to the length of a regular telephone conversation line. As technology advanced and the cost of transceivers and speakers began to drop, the two-ways began to serve as communications solutions instead of just simple communication devices. In fact, a two way radio used a separate signal, much like a telephone, to talk and to receive data. These devices were referred to as transceivers and as early transmitters.

Microwave Technology Advancements in microwave technology eventually brought about the invention of walkie talkies. Microwaves, much like radio waves, were able to cross great distances without the interference of other radio waves. A microwave transmitter was added to the mix, greatly improving the range and effectiveness of these devices. By adding an additional antenna, the distance could be extended and the two-ways would communicate much better than they ever did before. This same principle is used today when two-way radios are used to extend wireless coverage into large areas and to replace existing wired systems.

Walkie Talkies Today Walkie talkies are still one of the most popular types of handheld communication devices. Although they’re not always the most convenient, their ease of use makes them an ideal choice for many situations. Most walkie talkies can be used with regular landline phones or other wired communication devices, which means they’re perfect for military and public safety units. Furthermore, the ease of operation of a walkie talkie makes them a great choice for those who may not have access to cell phones or other wired communication devices.
