How PDA’s Work With 2-Way Radio Systems

A 2-way radio is a kind of walkie-talkie, but has additional capabilities. In fact, these radios are very similar to the walkie-talkies (the ones you hang around your ears) but have a built-in capability to communicate by either transmitting or receiving data. In other words, a 2-way radio can act like a telephone with an added built-in microphone. In addition to the standard voice channels for communicating with people, some 2-way radios include a Data Channel, which allows data to be communicated in the form of channel codes to other radios on the same channel. In other words, a 2-way radio can function much like an inexpensive walkie-talkie.

However, despite the similarity of the two-way radio and the walkie-talkie, there are differences that make them distinctly different from one another. For example, a two-way radio is not capable of receiving or transmitting data in the form of channel codes. This means that although you can use this type of radio to communicate with someone if they are on the same channel, you cannot use it to scan channels. However, most 2-way devices can be set up so that they can work as a walkie-talkie, allowing it to “talk” to other radio devices that are on the same channel.

A simplex radio communication uses four simplex channels. Each channel can be used for one particular function, which makes them very easy to learn and use. Two-way communications, on the other hand, use a variety of channels for different functions. For example, a normal two-way radio communication may allow a user to speak to someone on their personal channel and to talk to someone with the same simplex as them on another simplex channel. This is the reason why many walkie-talkie devices come with “extensions,” that allows users to talk to other individuals who are within a range of that person.

These days, however, two-way communications are being replaced by more sophisticated systems such as trunked radio systems. A trunked system is a single transmission channel that can carry both data and voice at the same time. The data stream can either come from an input source or it can come from an output source as well. The output is then sent to an antenna, which is usually mounted on the roof of a building, and this then receives the signal and transmits it to any appropriate receiver. Simplex radios will simply transmit a single channel signal, whereas a trunked system will allow a user to talk to multiple people at the same time.

As far as the voice quality is concerned, this varies depending on the type of channel being used. Most modern (and more affordable) radios will have various channel scan features, such as a scan frequency that allows the user to locate channels and transmit at a specific frequency only, or a search scan feature that will allow the user to scan a larger range of frequencies for even better results. In addition, some scanners will allow for the storing of custom lists of channels. All of these scan features are useful, but the advantage with a trunked system is that users do not need to configure each device separately and can instead just plug them all into one device, called a transceiver, and make a call.

Some phones, however, support three or more separate channels and some older phones support only two. In most situations, the push-to-talk devices that use the auto systems are less expensive and require less physical configuration, making them a much more attractive option for small business. Even if you cannot find a suitable push-to-talk device, you might be able to configure your existing phone to use the auto standard. Many older PBX systems already have built-in auto capabilities, so you may not even need to buy a separate unit.
