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.
- 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
- 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
- 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
