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.
