Walkie Talkie – What’s the Difference?

A walkie talkie, also known as a wireless personal communication device or WLL, is a hand-held personal electronic device which enables its user to transmit and receive voice over broadband (IP) air. This is done by creating an electromagnetic signal by dipping the two antennas into a transmitting tower. The transmitted signals are interpreted by the receiving station’s receiver and forwarded via radio channels for transmission to the end-user. The walkie talkie has evolved over the years to become a versatile piece of equipment. In the following paragraphs, we shall learn how the basic functions of a walkie talkie are explained and how they can be put to good use in everyday life.

One of the primary uses of a walkie talkie is to establish phone connections when you are in a potentially noisy area. For instance, if you are in the market of buying a car, you do not want to get stuck with a low quality, yet expensive pre-shared system that would not be compatible with your requirements. What you need is a system that you can use even when there are other people around at the same time. You can use this feature to avoid false charges by selecting the frequency, which is most appropriate for your call pattern. You will find that there are multiple frequency bands available and a considerable variation in the transfer speeds, although each band is likely to be a little cheaper than the others.

There are two main ways in which a walkie talkie operates. The first one is the discrete method and the second is the continuous frequency division (CFD). The former is the more popular of the two. This is because it is easy to operate and does not require any power output. This makes it ideal for hands-free operation and allows for greater freedom of movement when it comes to the positioning of hands. In this way, it is far easier to work on walkie talkie equipment than other systems which use constant power output with the result that they are often not suited well for hands free operation.

Constant two-way radios however are capable of transmitting over longer distances than the discrete systems and can only do so using less energy. In other words, they are better when used for communication purposes in large places where power supply is not a problem. Constant two-way radios are used frequently within factories or large buildings where their range is crucial. A walkie talkie however can be a good addition to this list of assets as well.

The walkie talkie uses a relatively simple technology in that it makes use of a transmitter that receives signals from a base station and then adds them onto a frequency band that is wider than the source of the signals. The way in which this is done is through a process known as Frequency Division Multiple Access (FDMA). Once this is done then a signal can be sent to multiple recipients at the same time. This is done by the transmitter sending a series of radio waves into the medium that is being used by the receiving device such as a microphone or a headset and then allowing the waves to be coupled onto the desired frequency band.

The other difference is that a two-way radio uses the push-to-talk button to send the signal to multiple users. Although the push-to-talk button is used to initiate communications, it is rather clumsy means of doing so. For this reason a number of two-way radios make use of a dedicated keypad which is used to provide users with options such as changing the frequency or transferring data. The walkie talkie makes use of a simpler system whereby the push-to-talk button initiating the communication is pressed rather than held down as is the case with the two-way radio.
