The X-LTE Extended Range 4G System provides high-speed Internet connectivity for vessels operating within range of terrestrial 4G/LTE networks. Its long-range maritime antenna and diversity technology are designed to improve connection quality and data throughput while operating offshore.

The system can use a local SIM card or multi-carrier roaming SIM, providing an alternative to satellite communications where suitable cellular coverage is available. AMI specifies a range of up to approximately 50 nautical miles, although actual coverage depends on the cellular network, antenna installation and operating conditions.

The AMI X-LTE Extended Range 4G System is a professional maritime 4G/LTE broadband communication system designed to extend mobile-network connectivity offshore. AMI’s datasheet describes it as a high-speed maritime LTE system with a rugged marine antenna and diversity technology for improved connectivity.
