Nextivity CEL-FI: selective mobile signal boosters – network-friendly & precise
The Nextivity family operates band-, channel- and carrier-selective and clearly stands apart from common wideband amplifiers found online. Thanks to IntelliBoost™, only the desired signal is amplified – interference-free and harmoniously integrated into the mobile network infrastructure.
Explore modelsWhy Nextivity over wideband?
- Selective, not blanket boost: amplification by band, channel & carrier.
- Interference-free & network-friendly: smart gain management prevents issues.
- Higher voice & data quality: targeted SNR improvement – no noise boost.
- Scalable: from GO/SOLO up to Quatra for large areas.
- Transparent control: app/cloud management, carrier selection, remote monitoring.
Selective vs. wideband – the difference
Nextivity (CEL-FI)
- Band/channel/carrier selective
- Adaptive amplification (IntelliBoost™)
- Harmonious network integration
- Predictable indoor coverage
Wideband amplifiers
- Boost everything – including noise & interferers
- Higher interference risk
- Little carrier selectivity
- Unclear results in complex buildings
