TETRA / TETRAPOL repeater
SEE Telecom designs and manufactures Tetra Tetrapol repeater systems
(BDA – Bi-Directional Amplifiers):
- To enhance the radio coverage of national public safety networks ;
- To extend the coverage of private radio networks in major infrastructures like shopping centers, exhibition halls,
convention centers, hospitals, confined areas such as service corridors, tunnels, underground car parks.
Monitoring and control can be done via SNMP, SCADA, via Ethernet using a web browser installed on a PC which gives access to the GUI, or remotely via an optional LTE modem that allows accessing the repeaters GUI from everywhere, using the 4G network and the third connector.
This interface contains an easy configuration page. The MC-DIRRAC also has a sum alarm output that can be connected to an external alarm system.
The Tetra repeater can be ordered with different frequencies, powers, different power supply voltages, with or without battery backup, and with a GSM modem.
Because each installation is unique, SEE Telecom proposes a complete portfolio of solutions with off-air and optical repeaters, advanced technologies as band selective, channel selective, AGC per time slot, squelch, frequency shifting, WDM, remote monitoring HTTP-SNMP.
