The DIB-R5 base station family is a constituent of the TETRA mobile radio system ACCESSNET-T IP and ensures the powerful and reliable mobile radio coverage of a specific area. Trendsetting TETRA Release 2 and TETRA Enhanced Data Service (TEDS) support make the Hytera DIB-R5 extremely attractive for all scenarios in which a high degree of availability as well as high speed data are a must. ACCESSNET®-T IP supports integrated Voice and Data services from the beginning.
Many mission-critical data applications have already been realized with ACCESSNET®-T IP. Today, we perceive more demanding data applications requiring higher data throughput. TEDS is our answer to this requirement and it is fully supported by the Hytera DIB – R5 family. With adaptive QAM multi-carrier modulation, the air interface dynamically adapts to a changing radio environment and uses the available spectrum most efficiently. With a radio channel bandwidth of 50 kHz, a gross bit rate of up to 150 kbit/s and a user data rate of about 80 kbit/s considering overhead and strong error correction are achieved. The Hytera DIB – R5 is already prepared for a channel bandwidth of up to 150 kHz to support even higher data rates.
The Hytera 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.
The Hytera 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. Different RF distribution system configurations are supported including motor tuned cavity combiner allowing remote frequency change. With its high output power of 25 W PSK modulated with cavity combiner at the antenna connector, reliable coverage is ensured.
