Clean and compact industrial design.
Intuitive LED UI.
Integrated antennas.
End-to-end cellular communication encryption without additional risk of vulnerability.
Support for the Nextivity Wave mobile application.
Unlocked: Cell phones do not need to be registered with Cel-Fi DUO to benefit.
Peaceful coexistence with adjacent Cel-Fi systems.
Patented 2-unit, 3-hop system.
Remote software update capability.
Engineering Mode
Mounting brackets included with every unit.
Wireless Features
Up to 100dB of system gain in each band, simultaneously.
Bluetooth Low-Energy (BT LE) communications with mobile handsets.
Max Band 2 and 4 EIRP for Multiple carriers: 16dBm downlink and 23dBm uplink, per band.
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 echo-cancellation.
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 two (2) cellular bands supported.
Cel-Fi DUO 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.
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 DUO 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.
Anyone can install the device. No special tools or knowledge required. No external antennas needed. Simply plug-in to power.
The unit can be proudly displayed, or easily placed in the background.
No additional equipment or professional installation required for full performance.
Users can be assured communications are secure, through the encrypted wireless link.
The included mount allows for the system to be wall-mounted or ceiling mounted, for maximum spatial flexibility.
Registration, Software Updates, and Engineering application support, with the Wave mobile app.
Any subscriber in the coverage bubble will benefit from improved coverage.
Multiple systems can be deployed without concern for mutual interference.
Allows quick and easy set-up by end-user. Provides instant visual feedback, with each unit displaying the system info.
Architecture allows user to place the coverage unit where it's needed and the Network unit where it gets the best donor signal.
Simplified remote maintenance of devices in the field, with Nextivity Connext cloud access.
Tech Mode, allows technicians to collect information quickly and easy for support or configuration issues.
Wireless Benefits
Clear and reliable voice connections within coverage area — up to 13,000 Sq. Ft.
Works on most cellular networks, globally.
The highest performance, fully-certified, signal booster possible in the power class.
Enables the system to communicate with smart phones and the Cel-Fi Wave mobile app, improving the user experience and adding capability to the product.
The three-hop two unit wireless system eliminates the requirements and restrictions associated with cabled connections.
Cel-Fi remains fully functional, even when there are other RF emitters present.
Ensures maximum gain - best coverage - at all times, without user intervention.
Subscriber devices enjoy significant improvements in battery life.
Real-time adapting capability ensures the best possible user experience, in actual user environments, which are constantly changing, and have a variety of Wi-Fi types and cellular signals present.
Linearity virtually eliminates all IMD desense issues.
Maximizes signal-to-noise (SNR) ratio, provides better data rates without negatively impacting macro cells.
Allows for 30dB more gain than Safe Harbor I – which means more coverage, safely.
A high-performance, six core processor, provides the engine to the Cel-Fi PRO.
Mobile Network Benefits
Easily support multiple band and frequency configurations on a cellular network with one device.
Support most network configurations of LTE and UMTS/WCDMA.
Reduce returns, customer care calls, and provide the best product experience to users.
Unlike wideband amplifiers, ensure the equipment capex benefits only your network – third-party macro cells are completely unaffected by Cel-Fi DUO.
Network operators can be assured Cel-Fi devices are being used as intended, with registration and location lock.
Completely network safe, doesn't affect macro capacity.
Ultimate control of the devices in the field resides with the network operator.
