Wireless 3G/4G/LTE Repeater Cel-Fi Duo

The Wireless 3G/4G/LTE Repeater Cel-Fi Duo is an intelligent solution designed to significantly improve mobile communication quality and internet signal in areas with poor reception. This powerful booster is compatible with all Ukrainian mobile operators' networks, effectively supporting 3G (WCDMA-2100) and 4G (LTE-1800) standards to provide stable internet and clear voice calls. If you are looking to buy a cellular repeater for your home or office, the Cel-Fi Duo is an ideal choice.

The Cel-Fi Duo operates as a two-unit system. The Network Unit, responsible for receiving the initial signal, is installed in the area of best reception (e.g., a windowsill or balcony). The second unit, the Coverage Unit, is placed indoors up to 25 meters away from the Network Unit. Communication between these units occurs wirelessly on the 5 GHz frequency, ensuring high stability and quality of operation due to the absence of interference in this band. This signal booster can provide an impressive signal gain of up to 100 dB, creating reliable coverage over an area of up to 1000 square meters. This dramatically improves mobile internet throughput by up to 4 times in areas with low signal levels.

This wireless signal booster, the Cel-Fi Duo, features an intelligent "Plug and Play" algorithm that automatically adapts to its surroundings and changes in mobile operator networks. Its Automatic Gain Control (AGC) constantly maintains the maximum necessary amplification, while automatic power management helps save battery life on your mobile devices. The repeater requires no operator permissions and is easy to set up thanks to its intuitive user interface. You can choose between two operating modes: supporting 3G+4G for a single operator (Kyivstar, Vodafone, or lifecell) or simultaneous operation with two operators, but only in 3G standard. For re-flashing the device, it is recommended to contact a specialized Authorized center. This is the perfect solution for anyone looking to improve mobile coverage and get stable 3G/4G internet in their home, apartment, office, or warehouse.

🎁 Expert Advice For the best results when installing the Cel-Fi Duo, first pinpoint the exact location for the Network Unit. Use a signal strength measuring app on your smartphone to find the spot with the most stable and strongest signal from the operator (usually near a window or on a balcony). The better the initial signal for the Network Unit, the more effective the amplification will be throughout your premises.
