Due to the need for efficient communication and quality, Kofre presents solutions for communication systems with strategically located conventional or trunked repeaters in order to successfully cover a given area.

Conventional Systems

The programming of a frequency is needed for each group (sector) who wants to talk independently.
In case the sector needs to communicate through larger distances, the installation of a repeater will be required.

The greater the distances, the more repeaters (one for each sector) will be required.

Trunking Systems

As more sectors request more channels, speak longer distances, a greater number of repeaters are required to provide communication. Depending on the number of sectors, a project may become unviable by occupying too much space in the telecommunications room, spending too much electricity and so on.

Thus the optimal use of repeaters became a necessity. Based on the concept of sharing, already used in telephone systems, a device called "Controller" was designed. Through it, a limited number of repeaters can be used by a large number of groups, precisely because when a repeater is not being used by a sector, it can be used by another.
