The amplifiers are characterized by very high (85dB) gain and efficiency. Parameters in the new DL/UL amplifiers are controlled by firmware enabling easy repeater configuration to the specific needs of the customer system.

The new generation of Radioteknik Tetra repeaters are offered in fibre-fed, inline or off-air versions, all of which can be high- or low-power, and can be delivered with battery backup. Replacing the previous generation first released in 2003, there are six repeaters in total available with many options to meet any customer requirement. Made-to-measure solutions are also available upon request.

With over twenty seven years experience in designing equipment and solutions for radio coverage in confined areas and areas suffering from propagation black spots, Zenitel Radioteknik is once again offering solutions which give outstanding radio performance, regardless of the environment. In locations as remote and diverse as metro systems, oil platforms and marine vessels, Zenitel's new Tetra repeaters can be controlled remotely as well as on site. For the ultimate in flexibility, remote control and monitoring can be done via GSM, TETRA, TCP/IP and HTTP.

Zenitel supplies proprietary supervision software SAMS (Supervision And Monitoring System) to offer a high degree of control over the repeaters, as well as comprehensive monitoring facilities. Additionally, a number of signals from external analogue and digital sources can be monitored. The supervision software can also interface to other control and monitoring systems to create a comprehensive site solution.

New and existing customers will be pleased to learn the repeaters benefit from an easy installation procedure and small volume cabinets combined with high repeater power.

For environments like tunnels, subway stations or anywhere where a high level of system robustness or redundancy is required, the repeaters can be equipped with dual fibre/antenna inputs and outputs. Optical fibre and antenna selection can be automatically performed by the repeater itself, or it can be controlled remotely by the system or the operators.

To meet the requirements of the authorities and mission critical users, the repeaters actively monitor the power sent to the antennas to avoid feedback and immediately detect antenna failure.
