Tetra Band-Adjustable Digital Repeater System / Digital 380MHz BDA System
Digital Tetra BDA Band Selective Repeater System

Tetra Digital Repeater is a telecommunications device used to extend the coverage range of Very High Frequency (Tetra: 30-300 MHz) digital radio communication systems.

Core Functions
  • Signal Reception: Receives weak/attenuated digital radio signals within the Tetra band from user equipment
  • Digital Processing: Decodes, regenerates, and error-corrects the digital signal
  • Signal Retransmission: Rebroadcasts the cleaned digital signal at higher power to distant or obstructed areas
Key Advantages
  • Extended Coverage: Overcomes terrain obstructions and Tetra range limitations
  • Signal Integrity: Regeneration prevents noise/error accumulation, maintaining voice/data quality
  • Spectral Efficiency: Supports digital modulation, 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
