Hyper-G: long-range 4G/5G that actually works at sea
A mast-top cellular dome with 36 high-gain directional antennas and up to 6 LTE/5G modems, built to keep your vessel connected for operations and crew welfare far beyond the harbour.
• 36 custom high-gain antennas with 360° coverage
• Up to 6 simultaneous LTE connections, always picking the best towers
• No RF loss from long RF cables – modems sit next to the antennas
Why your current 4G/5G fails the moment you leave the harbour
Most vessels run their cellular router below deck because it is convenient to access and easy to plug into the existing network. The antennas sit high on the mast and are tied to the router with long RF cables.
Those cables quietly kill performance. Every metre adds attenuation. The gain of the antenna is eaten by cable loss, so you end up with poorer reception, slower speeds, higher latency and a much smaller usable range than the theoretical “bars” suggest.
At the same time, omnidirectional antennas radiate like a flat donut. The more gain you add, the flatter and narrower that donut becomes. On a moving ship, that narrow vertical beam will happily overshoot or undershoot the cellular tower as the vessel pitches and rolls. On rivers or lakes, towers sitting on hills or buildings often end up outside the sweet spot of that narrow beam.
The result is predictable: unstable connections, frequent drops and crews complaining that the internet “just dies” as soon as you sail a bit further out.
Hyper-G moves the brains to the mast and fixes the physics
No signal loss from long cables
Hyper-G places the cellular modems inside the mast-top dome, right next to the antenna array. That almost eliminates RF cable between modem and antennas. The signal is preserved where it matters, so the system can deliver higher speeds, better stability and a much longer practical range. Data and power run back to the ship over a single coax, Ethernet or fibre link, depending on your chosen configuration.
Directional antennas instead of omni donuts
Inside the dome, Hyper-G uses directional antennas rather than omnidirectional ones. Directional panels provide high gain and a wide vertical beamwidth of around 60–70 degrees, depending on frequency. That wide elevation keeps the link inside the sweet spot when the vessel moves or when the tower is higher up on a hill or building. Where high-gain omnis go narrow and fussy, Hyper-G’s sectors stay powerful and forgiving.
36 antennas for seamless 360° coverage
Hyper-G combines 36 custom-designed high-gain antennas into an array that covers the full 360°. Your vessel can turn freely without hunting for a single “lucky” direction. Each sector is tuned to talk to the towers in its slice of the horizon for maximum throughput and stability at distance.
Multiple modems that pick the best towers
Hyper-G can host up to 6 individual LTE connections in a single dome. The system selects connections based on performance and availability instead of locking you to a single tower. That translates into higher average throughput, fewer drops when a cell degrades and the ability to use multiple operators and bands in parallel.
One mast-top platform for operations and crew
For operations
Use Hyper-G as a resilient high-throughput pipe for remote monitoring, telemetry and SCADA data, cameras and security feeds back to shore and maintenance access to onboard IT and OT systems. The preserved RF budget and directional array give you usable data connections much further from the coast, exactly where operations often need them most.
For crew welfare
Hyper-G also powers crew and passenger connectivity. It feeds your onboard Wi-Fi for cabins and common areas so crew can use video calls, social media and messaging, and stream content when the satellite link needs to be protected for business traffic. Heavy or non-critical traffic moves onto cellular whenever possible, protecting satellite bandwidth and making the internet feel more like home.
Choose how you want to use your modems
Hyper-G units are available in two service topologies, so you can match the system to your existing onboard network and traffic profile.
Bonded Hyper-G
Multiple LTE links are combined into a single logical connection. This is ideal when you need “unbreakable” connectivity, single VPN tunnels and large file transfers. If one link degrades, the others keep the session alive and smooth.
Load-balanced Hyper-G
Each device or VLAN on board can be distributed over the available links. This is ideal when you want to segment traffic by priority or department. It makes it easy to separate business-critical traffic from crew internet while still using all available capacity efficiently.
Modem options for regional and global fleets
Hyper-G supports multiple modem classes and regional variants, so the hardware can be matched to your coverage plans.
Supported modem technologies
LTE, LTE-Advanced and LTE-Advanced Pro, in CAT 4, CAT 6, CAT 11 and CAT 18 combinations.
Coverage profiles
Regional modem variants tuned to your main operating areas, and global variants for vessels that work across multiple regions and operators.
