Nextivity CEL-FI GO G41 - 4G/5G Intelligent Repeater

Single-operator, Bands: 1, 3, 5, 7, 8, 20, 28(U,L), 40

CEL-FI GO G41 offers a cost-effective and reliable solution to improve indoor coverage for 4G and 5G signals.

The Nextivity CEL-FI GO G41 is an advanced single-operator cellular signal booster that delivers enterprise-grade connectivity for small to medium-sized indoor environments. Powered by Nextivity's proprietary 4th generation IntelliBoost chip, this carrier-grade solution provides up to 100 dB gain to overcome challenging coverage scenarios where traditional repeaters fail. Designed for "small box" retail stores, branch offices, and residential applications, the GO G41 ensures reliable voice and data performance across 2G, 3G, 4G, and 5G networks.

Unlike conventional wideband repeaters that can introduce noise and interference, the CEL-FI GO G41 utilizes channelized signal boosting technology to selectively amplify specific carrier signals while maintaining network integrity. This unconditionally network-safe approach has earned Nextivity approval from over 200 mobile operators worldwide. The system can be installed in as little as one day, offering DAS-level performance at a fraction of the cost and complexity of traditional distributed antenna systems.

The CEL-FI GO G41 features flexible operator selection via the intuitive Nextivity WAVE App, allowing users to choose which mobile network operator signal to boost and easily switch between carriers when needed. For enterprise installations, the system can be remotely monitored and managed through the Nextivity WAVE Portal, providing real-time performance data and simplified troubleshooting capabilities.
