Cel-Fi[tm] PRO - Improve voice and data coverage for 3G/4G/LTE

The Cel-Fi PRO is designed to dramatically improve voice and data coverage in up to four bands for 3G, 4G and LTE.


Under the hood

Cel-Fi PRO improves 3G, 4G and LTE cellular service by eliminating dead zones and dropped calls. With 100dB of gain, Cel-Fi PRO will not only improve cellular service across four (4) concurrent bands, it will also reduce your cell phone’s power requirements and extend its battery life. Cel-Fi PRO covers up to 13,000 sq. ft. (approximately 1,200 m2) of indoor space per system. Cel-Fi PRO systems feature an LCD color interface, are fully self-contained and self-configuring, and require no external antennas or wiring. Simply plug it in to boost indoor cellular coverage.

Cel-Fi PRO is CE and FCC approved. It has been approved by numerous mobile operators and regulatory bodies, and is shipping globally.

Cel-Fi PRO EXA variants feature an external antenna connector to enable the use of an external Donor antenna. A Cel-Fi PRO EXA with an external Donor antenna can thereby acquire an outside signal, allowing it to be used in applications where no signal is present indoors (i.e. cement, metal walls, etc.). This opens up new opportunities for using Cel-Fi PRO Smart Boosters, when other solutions fail. Cel-Fi PRO EXA enables cellular coverage in hard to reach places by allowing the Cel-Fi Network Unit to be placed, where no service exists.

PRO Coverage Area

Move the CU further away from the NU to maximize coverage.

The total coverage area equals twice the distance between the NU and the CU. The maximum distance is up to 100 dB path loss.




* Plug and play, simple installation - no external cables, antennas, wires, or drills needed.

* Clean and compact industrial design.

* Integrated antennas.

* End-to-end cellular communication encryption without additional risk of vulnerability.

* Bluetooth Low-Energy (BT LE) communications with mobile handsets.

* Wirelessly (5GHz U-NII) linked Network and Coverage Units.

* Peaceful coexistence with adjacent Wi-Fi (2.4 GHz & 5 GHz), femtocell, and cellular devices.

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

* Automatic Gain Control (AGC) based on fast real-time echocancellation.

* Cel-Fi manages the power levels between the cell tower and user devices.

* Advanced digital echo cancellation (>30dB) and channel select filtering algorithms.

* Extremely linear RF front end.

* Adaptive signal equalization.

* FCC Safe Harbor II approved.

* Nextivity's 3rd-generation ARES chipset.


Mobile Network Features

* Up to four (4) cellular bands supported.

* Cel-Fi PRO simultaneously supports multiple carriers with bandwidths anywhere from 5 to 20 MHz with a total system relay bandwidth of 35 MHz.

* Support for 3GPP Rel. 10 features.

* Support for E-UTRA bands 1, 2, 3, 4, 5, 7, 8, 12, 20, and 28.

* Seamless integration with the Macro networks. No handset registration, GPS signal requirements, or call handoff problems.

* Remote Access from the cloud to the Cel-Fi device.

* Cel-Fi PRO boosts service only for the PLMNIDs the device is authorized and configured for.

* Secure and ciphered provisioning.

* Software-managed system intelligence prevents uplink system gain from exceeding path loss, which eliminates unnecessary rise in base station noise level.

* Uplink Muting Mode automatically shuts down uplink cellular transmissions when no active user equipment is detected.

* System shuts down upon Operator's network command or failure detection.

* Location Lock, which ensures the device is only being used in the location it was deployed to.
