Tetra Band-Adjustable Digital Repeater System 380MHz BDA with 80dB Gain and 33dBm Output Power
The Tetra Band-Adjustable Digital Repeater System is a professional telecommunications device designed to extend coverage range for Very High Frequency (380MHz) digital radio communication systems. This advanced system receives, processes, and retransmits digital signals to overcome terrain obstructions and range limitations.
- Signal Reception: Receives weak digital radio signals (DMR, dPMR, P25 Phase 2) from user equipment
- Digital Processing: Decodes, regenerates, and error-corrects digital signals
- Signal Retransmission: Rebroadcasts cleaned digital signals at higher power to distant areas
- Extended coverage up to 50 km line-of-sight
- Maintains signal integrity through digital regeneration
- Spectral efficiency supporting digital modulation (TDMA)
- Overcomes terrain obstructions including buildings and hills
- Digital filtering with adjustable bandwidth and three sub-bands per band
- Individual sub-band control with separate gain adjustment
- Donor signal monitoring for optimization and troubleshooting
- Intelligent algorithm to prevent uplink interference
- Self-control to minimize interference for new rollout e-Node B
