What is trunking radio in wireless communication?
Trunked radio systems are one of the most complex types of radio systems in use today. Trunked radios use several channels or frequencies, and allows those channels to be shared by a large number of users, in multiple talkgroups, without their conversations interfering with each other.
How do trunked radios work?
When a trunked radio user wishes to communicate with another user or group, the computer automatically assigns them the first free available channel to make each call. The underlying principle of trunking is that not all users or groups who need to communicate in a channel will do so at the same time.
What is trunking in a cellular radio system?
Trunking is a technique used in data communications transmission systems to provide many users with access to a network by sharing multiple lines or frequencies. As the name implies, the system is like a tree with one trunk and many branches.
What is the purpose of trunked radio system?
This arrangement allows multiple groups of users to share a small set of actual radio frequencies without hearing each other’s conversations. Trunked systems primarily conserve limited radio frequencies and also provide other advanced features to users.
When all radio channels are used in trunking system?
Effects of using all radio channels in a trunking system
- a. The user is blocked.
- b. The access to the system is denied.
- c. The queue may be provided.
- d. All of the above.
Can you listen to a trunked radio system?
Most scanners that can listen to trunked radio systems (called trunk tracking) are able to scan and store individual talkgroups just as if they were frequencies. The difference in this case is that the groups are assigned to a certain bank in which the trunked system is programmed.
What is the difference between trunking and conventional radio?
‘Trunked’ radio systems differ from ‘conventional’ radio systems in that a conventional radio system uses a dedicated channel (frequency) for each individual group of users, while ‘trunking’ radio systems use a pool of channels which are available for a great many different groups of users.
How does radio trunking work?
Trunked radio systems work by sending computer data between a mobile radio and a central controller. When a mobile radio user presses the push-to-talk button, the radio sends a digital message to the system controller requesting a channel assignment.
What is trunked radio?
A trunked radio system is a digital two-way radio system that uses a digital control channel to automatically assign frequency channels to groups of users. In a half-duplex land mobile radio system a group of users with portable two-way radios communicate over a single shared radio channel, with one user at a time talking.
What is two-way radio trunking?
Two-way radio trunking is simply a smarter and more efficient use of your frequencies enabling more people to communicate on a network with less busy tones. Rather than assigning a frequency for each talk group (dedicated channels) trunking enables you to communicate on just a few channels, which are shared without hearing unwanted communications.
What is trunked 2 way radio?
A trunked radio system is a digital two-way radio system that uses a digital control channel to automatically assign frequency channels to groups of users.
