The CEL-FI GO G41 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 GO G41 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 1,500 m² when configured with the included donor and server antennas, the system can be expanded with outdoor or additional server antennas for an increased coverage footprint.
This solution is ideal for use in commercial properties, government buildings, agricultural settings, small manufacturing operations, rural areas, businesses, and large 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. An internal donor antenna collects the best mobile signal from within the building and transmits it to a mobile signal booster unit. The unit strengthens the signal and rebroadcasts it around the building via internal donor antennas.What is Included in the Bundle?

• 1 x CEL-FI GO G41 Smart Signal Booster
• 1 x Nextivity CEL-FI Whip Antenna
• 1 x Nextivity CEL-FI Patch Antenna

The system needs to detect a minimum signal inside the building to operate.
