Hytera DIB-R5 - Digital Integrated Base Station

Reliable TETRA radio coverage and fast TEDS data transmission.

    Product description

    The DIB-R5 is the latest generation of reliable and powerful base stations by Hytera for ACCESSNET-T IP TETRA radio systems. Pioneering TETRA Release 2 and TEDS support make the DIB-R5 exceptionally attractive for all scenarios in which availability and high-speed data are a must.

    Product variants:

    • DIB-R5 advanced - modular and flexibly configurable base station with up to eight carriers
    • DIB-R5 compact - compact 2-carrier variant of the DIB-R5 with integrated hybrid combiner and minimal space requirement, even for the installation in standard 19" equipment racks. 

    DIB-R5 advanced

    The DIB-R5 advanced base station has a modular and flexible design. Main components are the Channel Units (transceivers), the Base Station Control Unit, the power supply and the RF splitting- and filtering equipment.

    Based on capacity requirements, one up to four Channel Units can be placed in one equipment rack. A capacity of up to eight carriers can be supported with an extension rack. All components are easily accessible and can easily be replaced. RF and power cabling are connected at the top of the equipment rack.

    DIB-R5 compact

    The DIB-R5 compact is a compact 2-carrier version with integrated hybrid combiner. With very small floor space and the ability to fit into a standard 19" equipment rack, installation costs are reduced and the transport to a site is simplified.

    Use in DIAMANT indoor radio system

    The DIAMANT indoor radio system is an intelligent solution to offer emergency services of the public safety organizations an absolutely reliable radio communication in the event of an emergency. The DIB-R5 compact in this solution is used as a base station for the provision of radio coverage. Learn more about the TETRA indoor radio system DIAMANT on the pages of our partner B-SCHMITT

    TETRA Enhanced Data Service (TEDS) capability

    The DIB-R5 is already prepared for a channel bandwidth of up to 150 kHz to support even higher data rates. The DIB-R5 Channel Units (transceivers) can be configured to support both, TETRA 1 PSK modulation for voice as well as TETRA 2 QAM modulation for TEDS. This simplifies spare part handling and allows a later upgrade to TEDS. 

    Redundancy options

    Important modules can be configured redundantly and are hot-swappable. Each base station supports transmission link redundancy and can be connected to two switching nodes. Sites under heavy load can be equipped with up to four control channels (SCCH) to provide additional capacity for signaling, text messaging or location update. 

    RF performance

    Different RF antenna coupling system configurations are supported, including motor tuned Cavity-Combiner allowing remote frequency change.

    With its high output rating of 25 W PSK modulated with Cavity-Combiner at the antenna connector, reliable coverage is ensured. Up to four RF carriers are supported in one equipment rack and up to eight carriers with a further equipment rack (for DIB-R5 advanced)

    Triple receiver diversity

    The DIB-R5 supports 3-way receiver (Rx) diversity and highest sensitivity to optimize the base stations radio characteristics and to reduce the number of base stations required to cover a certain area. 


    If the DIB-R5 should be isolated from the rest of the network, it still provides most of its features in local fallback operation. Especially security-related features like authentication and air interface encryption are supported. 

    GPS/Galileo/Glonass-based synchronization

    The DIB-R5 can operate with GPS-/Galileo-/Glonass-based synchronization, but also a permanent operation without satellite-based synchronization sources is supported. This allows a reliable operation even in underground areas or within buildings without the need of using an antenna for the reception of a satellite signal.
