What are the two modes in Tetra trunking radio system?

Following are the two modes in TETRA trunking radio system. Trunked Mode Operation (TMO): In TMO, communications are managed centrally through base stations and the network’s core infrastructure. It allows for wide-area wireless communication with the support of advanced features like group calls, emergency calls, and priority calls.

What is a trunking system?

Trunking systems allow different organizations to share radio spectrum and infrastructure resources. Previously, closed user groups like railway companies operated their own radio infrastructure, each using a separate set of radio channels.

What is a portable base station & repeater?

Enhance connectivity between landline and radio communications while extending coverage of your two-way radio network. Portable base stations and repeaters offer compatibility with both conventional and trunking systems in VHF, UHF and 800-900 MHz, while providing on-site repeater capability to extend radio coverage in your network.

Why is trunking important for a two-way radio system?

For two-way radio systems with many users in the same general region, licensing in the old way was no longer adequate. It became necessary to devise better techniques of utilizing those parts of the band, in order to allow for more efficient use of it by many operators. And this was the need that trunking was devised to address.

How do trunked radio systems manage channels?

In trunked radio systems, the channel selection is performed for each call, considering the actual traffic intensity. This allows for more efficient use of the spectrum by sharing radio channels, unlike traditional mobile networks for closed user groups that all used different radio channels.

How do users communicate on a trunked radio network?

Connection establishment on a trunked radio network is by push-button (push-to-talk). Trunked radio is typically used point-to-multipoint and thereby differs from cellular or cordless, where users communicate point-to-point.
