    VHF Digital Repeater system 150MHz digital band selective repeatre system for customized use


    Digital VHF band selective repeater system


    A VHF Digital Repeater is a telecommunications device used to extend the coverage range of Very High Frequency (VHF: 30–300 MHz) digital radio communication systems. Here’s a concise


    Core Functions:
    1. 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).
    2. Digital Processing:
    * Decodes, regenerates, and error-corrects the digital signal (unlike analog repeaters that amplify noise).
    3. 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.


    Feature
    * 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.
