What is a two -way radio?

Bidirectional radio or transceiver is a radio device that can transmit or receive audio broadcasting. Virtually everyone has used some type of two -way radio during their lifetime. The types of devices that classify as bidirectional radios range from simple "walking" or even children's monitors to cell phones used in everyday life.

Bidirectional radios generally come in two different styles, simplex and duplex. Simplex two -way radio is classified as one that uses one channel to transmit messages. This means that only one person in the conversation can speak and be heard at once. The most common type of two-way radio Simplex is a hand radio or walkie-talkie, which usually contains the "push-to-talk" button to incite transmission from one unit to another. Meanwhile, the duplex two -way radio uses two different radio frequencies at the same time, creating the ability to transmit a continuous conversation. Common examples of these types of two -way radios are the wayRobky man uses in their daily lives such as wireless or mobile phones.

both types of two -way radio have the ability to send data and sound with different abilities and limitations. Duplex bidirectional radio systems can transmit data from one point to the other in real time, while Simplex systems are delayed. There were also examples of radio that can use both simplex and duplex systems. This means that two radios can communicate simultaneously when they are to a certain extent, but can also communicate through one channel when they are out of range. A two -way radio with this ability is often referred to as a device, direct device or car device.

Analog technology uses some two -way paths, while others broadcast digitally and, as always, there are advantages and disadvantages of both. With an analog is a better ability of a communaKovat once are weak or noisy, but as mentioned above, only one side of the conversation can be held at a time. On the other hand, digital systems provide simultaneous communication and the ability to send more information than an analog, such as text messages. However, digital devices such as mobile phones must be designed to a certain standard, but are more expensive and quickly become outdated.
