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.

Why 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
