What is the radio communication system?

Radio Communication System is a collection of fixed and mobile radio equipment designed to serve the organization by allowing specific communication modes such as one-to-man and one-to-one. The common radio communication system uses one or more fixed sites that have the opportunity to repeat and convey messages to nearby and remote sites as needed. Bidirectional radio allows people to exchange messages, while radio broadcasting is only in one direction. Many frequency strips and modulation types are used for the radio communication system. Frequency from 0.3 megahertz (MHz) to about 3,000 MHz assigned to the so-called high frequency, very high frequency and ultra -rast frequencies for various specific needs are extra long range, all-heating and urban signal structures.

modern two -way radio systems), which is typically three user modes. Radio portable user has manual assonation-eceiver or transceiver, a device that runs on batteries andIt is easy enough to take almost anywhere, a mobile radio user usually has a transmitter mounted inside the vehicle and a user of a fixed or basic radio sits on a station with a stationary radio device. A portable radio can be transported and operated during stationary times. Radio Electronics has improved a lot since the beginning of the 20th century because there was a breakthrough in battery technology that increases the call time for portable radios. Some technologies even allow radio transmissions to automatic energy settings so that it corresponds to user -location relative to fixed stations.

radio communication system users are able to communicate with all group members at the same time. In practice, each group in the organization is awarded a real channel or a virtual private channel where the group can communicate without interference with the communication of another of another group. This function jE allowed by selectivity of the radio receivers used in conventional analog communication.

In conventional analog communication, channels are assigned to different groups, and if there are too many groups, the technique called trunking allows radio groups to have a virtual channel as needed. In this mode, the Trunking Form of Subscribable Units of Data Communication called Trunked Radios requires a system of communication communication. Instead of using the channel exclusively, exclusively requested radio will automatically require the channel without the user knowing. The user knows that there is access to a particular virtual channel or a Talk group. Go-Elaad climbs the user that a virtual channel has been created and that the user can already speak.
