CEL-FI ROAM R41 4G/5G Mobile Cellular Repeater | Zetifi

• CEL-FI ROAM R41 main unit
• Donor antenna (mounts outside the vehicle to capture tower signal)
• Server antenna (distributes boosted signal inside the vehicle)
• 12V automobile auxiliary power adapter with 5m cable
• Mounting screws and velcro pads
• Quick installation guide

Compatible with Telstra, Optus and Vodafone

The R41 supports a wide range of bands so it works with your carrier's signal regardless of which network you're on. Through the Nextivity WAVE app you can switch between Telstra, Optus and Vodafone to boost whichever network has the better coverage in a given location. Only one network is active at a time, and switching is done in the app.

4th Generation IntelliBoost Chip. 100 dB Gain.

The same IntelliBoost technology Nextivity deploys in enterprise building systems sits inside the R41. It delivers channelised coverage, meaning it isolates and boosts your carrier's actual signal rather than amplifying everything in range. System gain reaches up to 100 dB.

5G NR Low Band, 4G and 3G. Including Dynamic Spectrum Sharing.

Supports WCDMA, LTE and 5G Dynamic Spectrum Sharing (DSS) across bands 1, 3, 5, 7, 8, 20, 26 and 28L. The DSS capability means the R41 supports 5G NR Low Band, which is the 5G technology primarily used in regional and rural Australia, where it matters most.

Automatic Band Selection

You do not need to manually choose between 4G and 5G. The R41 reads what's available from your chosen carrier and locks onto the strongest signal band automatically. Voice, data and streaming get the best available connection wherever you are.

Plug and Play. Under-Seat Install.

Mount the unit under any seat using the included velcro or screw mounts, connect the two antennas, plug into the 12V auxiliary socket, and the system is running. No configuration required to get started. Dimensions are 170 x 79 x 43 mm and weight is 490 g, so it fits out of the way in any vehicle.

Pairs with Zetifi Cellular Smart Antenna

The Zetifi Cellular Smart Antenna is built and tested for the CEL-FI system, covering the full frequency range the R41 uses across Australian carrier bands. Together they form a system Nextivity's own CEO calls transformative, covering both today's terrestrial networks and the satellite-based services coming online in Australia.

WAVE App and MyWAVE App

The Nextivity WAVE App (iOS and Android) handles carrier switching and shows real-time system performance. The MyWAVE App manages band selection for users who want more granular control. Both are free.
