C2000 repeaters enhance RF coverage - Dutch C2000 safety communication requirements

SEE Telecom produces C2000 TETRA repeaters that enhance RF coverage in confined areas according to the Dutch C2000 safety communication requirements.

C2000 Tetra Repeater

The C2000 version of the MC-DIRRAC repeater enhances RF coverage according to the Dutch C2000 safety communication requirements.
  • To enhance the radio coverage of Dutch national public safety networks in major infrastructures like shopping centers, exhibition  halls, convention centers, hospitals, confined areas such as service corridors, tunnels, underground car parks.
The MC-DIRRAC C2000 processes up to eight channels, independently, both in frequency and in power, through per channel and per timeslot AGC/ALC functionalities and customizable filtering. Compared to the conventional MC-DIRRAC, it allows connecting the TETRA repeater to 2 different donor antennas, one for the uplink to the BTS, and the other for the downlink from the BTS.

The MC-DIRRAC C2000 has five RF connectors, two for the connection to the BTS to the antennas pointing toward the base station, 2 for point tests of each connection to the BTS, and the fifth one for the connection to the antennas or radiating cable in tunnel or building.

Monitoring and control can be done via SNMP, SCADA or Ethernet using a web browser installed on a PC with access to the GUI. This interface contains an easy configuration page. The MC-DIRRAC C2000 also has a sum alarm output that can be connected to an external alarm system.

C2000 Tetra 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.
