Two Way Radio
A two-way radio is simply a radio that can both transmit and receive (a transceiver). In broader terms, most of voice wireless communications systems , definition. two-way radio refers to radio system mainly used for group call communication. Two-Way Radio used for your business
1. Conventional System
Conventional system is the most basic radio communications system. Conventional, as its name implies, refers to a "traditional" method of frequency utilization. Conventional radios operate on fixed channels and each user group is permanently assigned a fixed frequency or a set of frequencies.
2. Trunking System
The concept of “trunking” is taken from telephone company technology and practice. It refers to the sharing of common “resources” among a number of different users on the same system without overhearing or interfering with each other’s conversations. Trunked takes advantage of the probability that in any given number of user units, not everyone will need “resources” access at the same time. Therefore with a given number of users, fewer discrete “resources” are required. In a trunked radio system, the system logic automatically selects the physical radio frequency channel (the resources) without user interference. There is a protocol that defines a relationship between the radios and the radio network which supports them. The protocol allows channel assignments to happen automatically. This arrangement allows multiple groups of users to share a small set of actual radio frequencies without hearing each others' conversations. Trunked systems primarily conserve limited radio frequencies and also provide other advanced features to users.
