Nextivity
Nextivity CEL-FI – selective mobile coverage solutions (not wideband)
Nextivity CEL-FI stands for precise, band- and operator-selective signal optimisation – designed for scenarios where reliable voice and data performance is critical. Unlike unselective wideband boosters, the goal is not to “amplify everything”, but to process usable signal in a controlled way – consistent, measurable and network-friendly.
The technical foundation is the proprietary IntelliBoost® platform (real-time DSP) – deployed in 100+ countries and used by 200+ mobile network operators. (manufacturer/partner statements)
Why Nextivity?
- Selective instead of “spray & pray”: amplification by band/operator – not uncontrolled broadband.
- Network-friendly & stable: controlled signal processing for long-term operational reliability.
- Practical, scalable portfolio: clear system classes – from smaller sites to large in-building projects.
- Transparent operation: status & configuration via app/management (model-dependent).
- Professional technology core: IntelliBoost® (real-time DSP) as the heart of the CEL-FI platform.
Selective vs. Wideband – the key difference
| Technical aspect | Nextivity (CEL-FI) | Wideband boosters |
|---|---|---|
| Amplification principle | Targeted / selective | Unselective across wide bandwidth |
| Signal quality | Controlled processing | Results heavily environment-dependent |
| Network compatibility | Designed to be network-friendly | Higher risk of mis-adjustment/interference |
| Long-term stability | Built for continuous operation | Often unstable when networks change |
This delivers a network-friendly, stable and long-term operational in-building coverage approach that meets the requirements of professional in-building installations – in clear contrast to unselective broadband technology.
Which Nextivity system class fits?
- Buildings (small–mid): targeted optimisation for defined indoor areas.
- Vehicles / mobile use: stable coverage on the move or in changing locations.
- Large sites / in-building (Active DAS): scalable distribution across multiple coverage points (e.g., QUATRA).
