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
