The ‘hand-held trans receiver’ or walkie talkies radios as it is popularly called was developed by two engineers during world war-2 for communication on the war field. After the second world war was over, the invention slowly spread to commercial places, armed forces and field of work.
Major characteristics of walkie talkies radios include a half-duplex channel mode of communication where only one way of communication is possible. At a time , one person can talk and others can listen. There is a Push To Talk (PTT) facility which is available for people to assign priority among the speakers. Walkie radios is commonly used by traffic policemen on the roads to transmit traffic information between two places. The first radios was developed by Motorola and even now continues to be the lead in introducing newer models. Every talkies radios device comes with a talk band. It is the distance which is supported by the radios. Some advanced models support distances of 5km up to 20 km.
With cell phones having dominated the communication market, walkie talkies radios applications may look to be shrinking. However, these radios have some disticnt advantages over the cell phones. They were designed to be used in critical situations and hence their signal strength is very strong. They can be conveniently used during severe storms and bad weather conditions also with equal ease. A cell phone might not be that useful when there is a natural calamity. Hence,in applications where safety and security are mandatory, the radios are a must and are far better than mobile devices.
An advancement in the walkie talkies radios device is that it has been made into a two-way device. There is a dual channel in which simultaneous transmission and reception is possible. It is also been called a ‘two-way talking radio’. Walkie-talkie’s of today come as a package. For instance, one model comes with an emergency powering mode with a hand crank, flash light, clock with an alarm etc. This unit as a whole with the main walkie-talkie with the accessories is very useful for people in rescue operations or in traffic or controlling vehicular movement in a huge campus.
Operation of a radios is very simple. For two people to communicate, their radios should be set at the same frequency. Then at a time one can talk and the other can listen. For group discussions, again the group has to be created using the same frequency. The technique of Push To Talk can be employed when a group of people are talking.

Walkie Talkie Radios
A vital communications device during the Second World War; the invention of walkie talkie radios has been attributed to Canadian inventor Donald Hewes Kings, and American born Irving J. Gross. Between these two pioneers, the first push and talk walkie talkies were patented and rolled by American communications company Motorola.
The advent of the Second World War heralded a new era in communications technology – the first walkie talkie devices being of back-pack size, and fulfilling the great need for 2 way communications for ground-based operations.
The early “walkie talkie” (Motorola SRC-300) was so named because of it's portability, despite weighing nearly 40 pounds. It was transported on the backs of troops within a specially constructed casing similar in size to a back-pack. The design itself is somewhat alien to the minuscule models of today, with the vacuum transmitter/ receiver alone taking up a fair proportion of the internal component space. The battery also was considerably large for this war-time communications device. The SRC-300 was extremely powerful given that it was the first model to be mass-produced. (Over 50,000 were made for the war.)
Using the shorter of the two antenna, troops could avail a range of 0.5 to 1 mile, while the extended aerial allowed communications over a 3-mile radius. Latter improvements to the model included the implementation of a single tuner, eliminating the need for manual tuning every time a member of U.S infantry wished to convey a message to other personnel.
Considerable improvements were made to both the design and technology of walkie talkie radios between the late 1950's to early 1970's when they were used by military and security personnel on patrol within large American cities. By 1970, the size of these devices had considerably reduced, to the extent they could be mounted to personnel helmets.
By 1980, the popular walkie talkie radios were being mass produced, and were of a size that made them both light and portable. Everyone from shop security staff, to airport groundsmen were utilizing this technology for essential communications – while children were unwrapping toy models at Christmas. These play-things usually had a very short radial range (up to 200 metres), however the licensed models could reach a range of up to 6 miles.
Commercial walkie talkies also became known as hand-held transreceivers or “H. T’s”, capable of “wide-band” communication via a radio scanner. This meant that a number of walkie talkie radios could be used on one frequency, and each holder could communicate across a wider territorial area.
Today, walkie talkie radios are used by just about every commercial service you can think of; from retail to airport security, police officers to army personnel. Licensed models have a far wider range than was ever thought possible, favoured by mountain climbers and hikers to keep in touch with comrades in extremely isolated conditions.
If you're intending upon purchasing a walkie talkie radio for professional use, such as within a taxi service or something similar, you will need to opt for the variant which operates using a frequency transmitted from a central scanner. This type allows the multiple use of a frequency for communication among several parties – ideal for taxi drivers reporting back to base. Alternate variants use a C.B radio system to which they connect for multiple or wider transmissions. Such variants are still used among the armed forces.
Licensed transreceivers tend to use a U.H.F (Ultra-High Frequency) reserved mostly for professional and commercial use, avoiding any interference from transreceivers used within domestic environments. C.B (Citizens Band) operates at a frequency of 27MHz, used by licensed hand-held radios, while the 49 MHz frequency is utilized by domestic models and 2-way baby monitor systems.
Modern walkie talkie radios don't differ all that greatly from their 1940's counterparts, apart from size and the range it is now possible to achieve. Users still rely upon the P.T.T (Push To Talk) concept, whereby a button must be pressed prior to communication. The listener must wait until the message is relayed prior to responding.
Most models, whether domestic or licensed, feature a tuning dial in order to “fine-tune” to the best frequency. Domestic models operate under the PMR446 (Private Mobile Radio), the frequency being 446 MHz, with around 40 channels. This frequency does not require licensing for use, and is generally the only frequency available on high-street walkie talkie radios.
Modern walkie talkies represent the most versatile form of communications device, aside from mobile phones. Weighing between 100-200 grams, most types will work with little interference over a range of 2-4 miles. In terms of power usage, most walkie talkie radios take either AA batteries, or can be recharged electronically.
Battery life can typically extend to around 20 hours. Domestic walkie talkies are quite versatile in that they can operate between 7-19 channels, switch-able if you are in close proximity to other users on the same frequency. Advanced models benefit from a voice-scrambling capability which assures privacy when conversing over any frequency.

Frequency Considerations for Recreational Walkie Talkies
If you are in the market for walkie talkies for personal use, you have an immediate and important choice to make: What radio frequency band do you require?
Frequency! Walkie talkies obviously utilize 'wireless' communication methods so when using a 2 way radio you are transmitting and sending your message through the air -- the same air that is currently carrying television signals, commercial radio signals, Ham radio signals and literally thousands of signals from other private walkie talkies. The Federal Communications Commission (FCC) has the job of controlling all of these communication signals so they don't run into each other; to accomplish this they have reserved frequency bands for use by certain types of communication (signal sending) devices. There are two frequency bands in use for recreational walkie talkies, these are called Family Radio Service (FRS) and General Mobile Radio Service (GMRS).
The FRS band! In 1996, the FCC reserved a set of radio frequencies they called the Family Radio Service (FRS) band, specifically for short-range walkie talkies (radios that operate no more than 2 miles away from each other) with a small power output (up to 500 milliwatts or one-half watt).
The GMRS band! About fifty years before the FCC created the FRS band they had reserved a set of frequencies for higher power walkie talkies that operated over a longer range this is the General Mobile Radio Service (GMRS) band. The GMRS band is for radios with a power output between one and five watts and a range greater than 2 miles. The FCC regulates walkie talkies that operate on the GMRS band and requires users of this type of radio to obtain a license and pay a fee. The GMRS license is good for five years and costs $80.00; the license must be obtained by an adult (the radios operating under the license may be used by minors but only with the licensed adult's knowledge and permission).
When buying walkie talkies, your choice is between a set of radios that operates only on one of these frequency bands or a set of radios that is able to operate on either one of these frequency bands. This determination will obviously have to be made based on the maximum distance the radio users will be from each other. If the radios are to be used within two miles of each other, FRS will be the best (and least expensive) choice. If a greater distance is consistently required, walkie talkies that operate on the GMRS frequency band will be required. If the need for distance is uncertain or if you want the option of occasionally transmitting up to five miles a FRS/GMRS hybrid is the radio set to choose.
