Product Description

Product Description

BF-TR951 DMR Stackable Trunking Base Station

BF-TR951 DMR fixed stackable base station supports PDT Trunking/DMR Trunking. It is the ideal choice for wide-area Trunking networking and large-capacity indoor deployment. The BF-TR951 delivers rich applications including voice communication, Trunked dispatching, data transmission, network management, and positioning systems, provides reliable communication guarantee and efficient data transmission for mission-critical users to work with safety and efficiency.

Multi-carrier Expansion
BF-TR951 can flexibly upgrade and expand system capacity based on user requirements, supporting up to 8 carriers, and meets the application requirements in high user density areas and high traffic assurance zones while carrying a larger volume of Trunking services.
 
Stackable Unit
The BF-TR951 has its main units distributed within the cabinet, including the base station control unit, channel unit, power supply unit, and RF transceiver system. These units are installed in a stacked configuration, ensuring more flexible base station construction even when cabinet resources are limited.
 
Military Grade
The BF-TR951 digital base station is designed with military-grade, featuring an all-cast aluminum structure to endure high-intensity operation. With excellent heat dissipation, it guarantees stable operation even when the internal cooling facility fails.
 
UHF/VHF Band, Wider Coverage
The BF-TR951 base station provides Trunking communication coverage in VHF or UHF frequency bands, effectively addressing network coverage issues in different scenarios of mountains and city areas. Providing more efficient daily management and command dispatch, as well as enhancing remote management and control capabilities.
 
Enhanced Failure Fallback
The BF-TR951 base station features failure fallback technology that allows it to automatically enter failure fallback mode when the core network link fails or the base station and core network transmission fails; When the localized channel unit fails, it only reduces the channels without affecting the base station's functionality; When the base station is disconnected from the core network, the whole station can fallbacks to the one-site mode.

Simulcast Technology
The BF-TR951 fundamentally solves issues related to same-frequency base station coverage and networking. It allows adjacent base stations to be deployed at the same frequency, ensuring smoother transitions between terminals and base stations. Enhancing signal coverage and quality, guaranteeing multi-point coverage, and making the signal more even. This technology enables all-network communication with a single call, eliminates co-channel interference in overlapping signal areas between base stations, and automatically switches to single-site mode when a base station fails, effectively improving frequency utilization and reducing extra frequency application and occupation.

One-site networking solution

Flexibly networked based on user requirements and achieve one-site networking application.

One-Site Multi-Base-Station Solution
