Frequency-Selective NCR
Sub-Band and Channel-Specific Repeater Amplification
Filters and amplifies only the operator's specific licensed carrier frequencies, rejecting adjacent competitor channels and out-of-band interference.
Technical Explanation
Broadband repeaters amplify all signals in the air, creating severe inter-modulation distortion with adjacent operators. Rel-18 Frequency-Selective NCRs incorporate programmable digital channelizer filters that isolate the host operator's exact 100 MHz channel allocation, suppressing out-of-band energy and preventing regulatory interference disputes.
Key Functions
- Isolates and amplifies only the host operator's licensed carrier bandwidth
- Rejects adjacent channel interference from competing mobile network operators
- Suppresses out-of-band spectral regrowth and intermodulation distortion
- Complies with strict national spectrum licensing regulations worldwide
