VHF Digital Repeater System 150MHz Digital Band Selective Repeater System for Customized Use
Digital VHF BDA Band Selective Repeater System
A VHF BDA Digital Repeater is a telecommunications device used to extend the coverage range of Very High Frequency (VHF: 30-300 MHz) digital radio communication systems.
Core Functions
Signal Reception: Receives weak/attenuated digital radio signals (e.g., DMR, dPMR, P25 Phase 2) within the VHF band from user equipment (e.g., handheld radios)
Digital Processing: Decodes, regenerates, and error-corrects the digital signal (unlike analog repeaters that amplify noise)
Signal Retransmission: Rebroadcasts the cleaned digital signal at higher power to distant or obstructed areas
Key Advantages
Extended Coverage: Overcomes terrain obstructions (buildings, hills) and VHF range limitations (~5-50 km line-of-sight)
Signal Integrity: Regeneration prevents noise/error accumulation, maintaining voice/data quality
Spectral Efficiency: Supports digital modulation (e.g., TDMA), enabling multiple users on one frequency
Features
Digital filtering supports adjustable bandwidth, each band supports three sub-bands
Each sub-band is turned on and off, and gain control is performed separately
Donor signal monitoring for easy optimization and troubleshooting
Intelligent algorithm to prevent UL interference
Self-control to minimize interference for new rollout e-Node B
