Product Description

The Cel-Fi CONNECT C41 Smart Signal Booster is a premium mobile phone signal booster that strengthens your 3G / 4G / 5G signal coverage. It is the most powerful carrier-grade solution available, delivering 100dB signal gain with the class-leading voice and data wireless performance. Cel-Fi CONNECT C41 is designed to solve cellular coverage issues for indoor environments and does not interfere with other wireless devices. In addition to providing cellular coverage up to 200 m2 in its plug-and-play configuration, the coverage footprint can be increased up to 1,000 m2 by expanding the system with optional donor and server antennas.
This multi-carrier solution is ideal for use in small offices, retail and homes.How does it work?Cel-Fi mobile signal boosters improve signal between a mobile phone and a mobile network tower, allowing you to have clear voice conversations and a stable data connection when you are inside. The donor antenna collects the best mobile signal from inside the building and transmits it to the main unit. The unit strengthens the signal and rebroadcasts it inside the building.What is Included
