  • Fully wireless, plug-and-play architecture for supporting band II and IV or band II and V - WCDMA/HSPA+ with up to 100 dB of system gain.

  • Maintains end-to-end cellular communication encryption without additional risk of vulnerability.

  • Peaceful coexistence with adjacent Cel-Fi systems, 802.11a/b/g/n, cellulars.

  • Nextivity’s IntelliBoost Baseband Processor II

  • Patented 2-unit, 3-hop system allows flexible placement for optimal coverage.

  • Multi-core processor running advanced digital echo cancellation and channel select filtering algorithm.

  • Software-based optimization of integrated antenna coverage pattern which maximizes system gain and provides improved coverage and signal quality.

  • Automatic Gain Control (AGC) continuously monitors system path loss and transmit power to deliver maximum gain, independently for each channel.

  • Intuitive LED User Interface allows quick and easy installation by end-user.

  • Securely provisioned operation with ciphered software which only operates on authorized carrier’s network.

  • Network-safe algorithms prevent uplink system gain from exceeding path loss, and eliminates unnecessary rise in base station noise level.

  • Uplink muting mode automatically shuts down uplink cellular transmissions when no active user equipment is detected.


Pure plug and play:
No need for external antennas or cables. It auto-configures itself right out of the box.

FCC compliant:
Cel-Fi is the only booster approved by the FCC for 100dB gain – that’s 1,000 times greater gain than analog boosters.

Carrier approved:
Cel-Fi has been approved by T-Mobile and AT&T for use on their networks.

Advanced technology:
Cel-Fi system is powered by two proprietary multi-core processors.

Wider coverage:
users get up to 13,000 sq. ft. coverage, making it ideal for large homes and offices.

Radically different from traditional repeaters, Cel-Fi is the only intelligent booster thats wireless-in/wireless-out. The Window Unit receives the signal from the mobile network (it works with as little as one bar, or -104 dBm RSCP) and relays it wirelessly to the Coverage Unit that amplifies it for up to 100 dB of gain.

Fast data speed:
For indoor areas with poor reception, Cel-Fi offers significant data speed improvements – often in excess of four times the current rate.

Easy on mobile phone battery:
When a mobile phone no longer has to use all of its energy trying to reach out to a far away cell site, it lasts longer and requires less charging.

Ease of installation:
Cel-Fi is a true “Plug and Play” system that doesn’t require the installation of external antennas, bulky coaxial cables, handset registration, or a configuration setup by the user. In fact, Cel-Fi intelligently and automatically senses and adapts to its environment – including to changes made by your carrier, or to changes caused by nearby equipment like Wi-Fi, or other Cel-Fi devices.

Self adjusting:
Cel-Fis embedded system-on-a-chip technology automatically selects the correct frequencies for your carrier.
