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.
