A walkie-talkie is a portable, two-way radio transceiver. Walkie-talkies have been used as early as World War II. Today, its scope and application is broad and varied.
The technology used in Walki-talkies is what is known as frequency modulation. This conveys information over a carrier wave by varying its frequency. It looks quite similar to a typical telephone set with an antenna sticking out from the top.
Walkie-Talkies can be designed to be used for consumer or commercial equipment. The commercial ones are generally available with a metal case and have limited frequencies programmed into it. However the consumer equipments are made small, often light weight and have the capacity to access any channel within the specified band and not just limited assigned channels.
Walkie-Talkies serve as an excellent, mobile form of wireless communication within a specified range or area. It helps in communicating from one to many in a single talk. The utility of a two-way radio is immense. Its use can be found in refineries, oil exploration, marine industries, aviation services, event organizations, etc. One cannot rule out its effective usage in hospitals, clinics, and on roads to maneuver the traffic and it is surely a great tool in case of emergency. During calamities and in remote places, this mode of communication is still a widely used one. Walkie-Talkie instruments, or the two-way radios, are the cheapest yet most useful modes for direct communication.
While purchasing a Walkie-Talkie, one must check out all the varieties and, depending upon its usage, one can select the set. They are available with a variety of headsets for better sound quality and comfort.

The Walkie-Talkie set should be wiped with a moist cloth to keep it clean. It is advisable not to use any liquid chemicals or solvent that might damage the look of the set.
To avoid premature wear and tear of the parts, try to keep the set away from dirt and dust.
Fresh batteries of recommended size and shape should always be used. Old batteries need to be frequently checked and replaced.
Checking of batteries at frequent intervals is essential to see if there is any leakage. Leakage can lead to loss of chemicals that might damage the electronic circuit.
Practicing these tips and keeping them in mind while using the Two-Way Radio sets can increase its efficiency manifold.
