Marine Mobile Signal Repeater for Reliable Voice and Data Connectivity

The CEL-FI ROAM R41 improves mobile voice and data connectivity across boats, ships and other marine vessels operating in areas with weak cellular coverage. Approved for use with Telstra, Optus and Vodafone networks, it supports 3G, 4G and 5G DSS and can be switched between supported carriers as required. The compact, low-profile housing allows discreet installation within a vessel, while Nextivity’s 4th generation IntelliBoost technology provides channelised amplification of the selected mobile network operator signal. It is also a suitable replacement for CEL-FI GO G31 Mobile systems.
