What are Walkie Talkies?
A walkie Talkie is a two way transmission and reception radio that is used in communication between 2 people or a group of people. It works on a half duplex channel which means that there can be only one person sending out radio signals at a time while one or more can receive the same.
What is the difference between a mobile phone and a walkie talkie? The main differences between the two are:
A mobile phone works only in places where there is a network tower found. This tower helps in transmission and reception of signals. A walkie talkie requires no such tower. Hence it can be used in any terrain
Distance is not a factor for communicating through mobile phones. Walkie talkies work only when both the transmitting and the receiving radios are at a certain distance from each other. If the distance exceeds, walkie talkies are of no use
What does communication range of walkie talkies mean?
The distance between which two walkie talkies can effectively communicate without interference is called the communication range.
The tall claims of most walkie talkie brands
There are products sold in the market that claim to have a communication range of almost 12 km! Experts explain how this is calculated.
Most ranges are calculated on a flat terrain where the transmitter and the receiver are placed at line of sight with no interference at all in between. Sadly this is not how a customer intends to use a walkie talkie. Interference like buildings, trees, walls etc reduces the communication range considerably. Hence it is wiser to not fall for such claims and analyze the product well before investing.
