Mobile two way radios are a more convenient and relatively low priced way of communication. Two way radios are transceivers – that means they could both transmit and receive messages simultaneously. They are unlike broadcast receivers (including the ordinary radio) which only receive messages or signs. A good case of the two way radio concept is that the mobile phone and also the hand held radio known as the walkie talkie. There are various categories of mobile two way radios and each has its own advantages and the conditions for which it’s most appropriate.
The traditional portable two way Internet Radio operate on a fixed RF (radio frequency) channel. Even where a two way radio has the capability to tune into more than one channel, the consumer must select only one because the radio can only operate on a single channel at one time. Radios with multiple channel capacity have a button or a channel selector as part of their control panel. Frequently, the frequency regulator responsible for a certain area will devote unique channels to various organizations. As an example, one channel can be assigned to a cab company in order to ease communication between the dispatcher and the taxi drivers.
A trunked radio is another type of mobile two way radio – it utilizes a set of pre defined rules to automatically pick the radio frequency channel by itself. Digital versions of the trunked radio have the ability to multiplex – Quite simply, they could manage multiple conversations using the exact same frequency channel.
The other sort of portable two way radio would be the duplex radio. It can transmit and receive messages on different frequency channels. Equipment utilized for communication in a duplex system can only operate where there is certain core infrastructure such as a repeater and a base channel.
There are three sorts of duplex system radios – the half duplex which requires the user to press a push button prior to relaying a message, the complete duplex that can simultaneously receive and transmit signals and also the hybrid duplex which applies the half and full duplex programs. The advantage of this type of radio is its ability to expand the geographic area within which communication takes place between the users.
Another classification of mobile two way radios is the analogue radio and the digital radio. The analogue comprises the AM radios used in aircraft along with the walkie talkie. Its benefit is that, in regions with weak signals it’s a much better ability to convey (but just provided good quality equipment is used). The electronic radios include the standard safety radio. This portable two way radio allows simultaneous communication between multiple users and may also send non voice data such as text message.
