Why should vessel owners choose for cellular connectivity?
-
Globally Deployed & Trusted
4G is a mature, globally standardized technology used by billions of devices across every continent — from international ports to offshore rigs. Its scale ensures consistent quality, broad compatibility, and ongoing vendor support. -
Carrier-Grade Reliability
Built on years of refinement, 4G networks deliver uptime and stability trusted by critical sectors including emergency services, logistics, and maritime operations. -
High Throughput & Low Latency
With speeds up to 100 Mbps+ in maritime environments (and higher nearshore), 4G supports high-bandwidth applications like video conferencing, remote diagnostics, and live data streaming with low latency — often under 50 ms. -
Seamless Handover & Roaming
Advanced handover algorithms and global roaming agreements ensure uninterrupted connectivity across regions and operators, critical for moving vessels and mobile IoT. -
Long Lifecycle & Future Compatibility
4G is not going anywhere. It will continue to be supported alongside 5G for at least another 10–15 years, making it a safe and forward-compatible investment for fleet operators. -
Robust Security Protocols
With features like IPSec tunneling, SIM-based authentication, and end-to-end encryption, 4G networks offer enterprise-grade security trusted in defense and government use cases.
Proven Today. Ready for Tomorrow.
4G isn’t going anywhere. It’s fully compatible with 5G and will be supported globally for over a decade. That’s a future-proof investment that keeps paying off.
