BDBOS Tetra Repeater

SEE Telecom designs and manufactures TETRA BDBBOS repeater systems (BDA – Bi-Directional Amplifiers):
  • To enhance the radio coverage of German national public safety network BDBOS in major infrastructures like shopping centers, exhibition halls, convention centers, hospitals, confined areas such as service corridors, tunnels, underground car parks.
The Tetra BDBOS repeater comes in the form of a 19-inch rack with 2 RF connectors, one connected to the antenna pointing to the base station and the other connected to antennas or cable radiating in a tunnel or a building.

Monitoring and control can be done via SNMP, SCADA, Ethernet via a web browser installed on a PC giving access to the graphical interface, or remotely via an optional LTE modem to access the graphic repeater interface everywhere thanks to the 4G network. This interface contains an easy configuration page.
The BDBOS Tetra repeater can be controlled with different powers (low, medium, and high), different supply voltages, with or without battery backup, and with an LTE modem.

The Tetra BDBOS repeater is approved in most Länder for use on the German network.

BDBOS repeaters are available in optical-to-RF (OMU) and RF-RF (off-air repeater) formats. 

OMU consists of a Master station distributing the RF signals to remote units (ORU) with optical transmitters and optical receivers, by optical fibers. These Optical Remote Units (ORU’s) transform the optical signal into RF, amplify it, and then deliver it to the infrastructure at the appropriate power level.

The off-air repeater has two RF connectors, one connected to the antenna pointing toward the base station, and the second one is connected to the antenna or radiating cable in the infrastructure itself.
