Providing WiFi connectivity on board mercantile vessels presents unique technical challenges. Satellite connections introduce high latency, limited bandwidth, and intermittent availability - conditions that cloud-based captive portals are not designed to handle.
WifiGem Captive Portal is an on-premises solution specifically suited for maritime environments, where reliability, performance, and data control are essential.
Why Cloud Captive Portals Fail at Sea
Most cloud captive portals rely on continuous communication with external authentication servers. This model assumes stable, low-latency internet connectivity - an assumption that rarely holds true on vessels using satellite links.
Common issues with cloud captive portals on ships include:
* Slow or failed login page loading
* Authentication delays caused by satellite latency
* Login failures during temporary WAN outages
* Increased user frustration and support requests
When the captive portal itself depends on the satellite link, any degradation of the connection directly affects user access.
On-Premises Captive Portal Architecture
WifiGem is designed to run on board the vessel, inside the local network. Authentication, session management, and policy enforcement occur locally, without requiring constant access to external cloud services.
This architecture ensures:
* Immediate loading of captive portal login pages
* Local authentication even during unstable satellite conditions
* Continued operation during temporary WAN interruptions
Internet connectivity may be variable at sea - authentication should not be.
Optimized for Satellite-Based Networks
WifiGem has been successfully deployed on mercantile vessels where satellite connectivity is the primary WAN link. Its architecture allows operators to maintain a consistent user experience despite the inherent limitations of satellite networks.
Primary key benefits:
* Predictable login performance
* Reduced dependency on external services
* Lower operational risk during connectivity degradation
By keeping authentication local, WifiGem minimizes the impact of latency and packet loss on the user experience.
Full Control Over Guest and Crew Access
WifiGem is more than a captive portal. It functions as a complete network access control platform, allowing administrators to define detailed policies for guest and crew connectivity.
Capabilities include:
* Authentication for wired and wireless devices
* Per-profile bandwidth control
* Session time and traffic limits
* Real-time monitoring of active connections
These features are particularly important in environments where bandwidth is costly and must be shared fairly.
Data Sovereignty and Privacy Compliance
Storing authentication data in external cloud services introduces privacy and compliance challenges, especially in international maritime operations.
With WifiGem:
* All guest and crew data is stored locally on board
* No mandatory data transfer to third-party cloud platforms
* Configurable data retention and automatic cleanup
This approach simplifies compliance with privacy regulations such as GDPR and gives operators full control over sensitive information.
Suitable for Single Vessels and Entire Fleets
WifiGem can be deployed on a single vessel or across an entire fleet, with centralized administration available when required.
It supports:
* Data import/export for consistent login experiences across multiple vessels
* Centralized management for fleet operators
* Integration with existing onboard network infrastructure
The solution adapts to the operational needs of both individual ships and large maritime organizations.
Test WifiGem in Your Maritime Environment
Every vessel network is different. For this reason, WifiGem is available as a virtual appliance that can be installed and tested directly in your environment.
Operators can:
* Deploy WifiGem on board
* Test performance under real satellite conditions
* Receive complimentary pre-sales consultancy from the WifiGem technical team
This ensures the solution meets operational requirements before deployment.
A Captive Portal Designed for Real Maritime Conditions
Cloud captive portals are built for ideal connectivity scenarios.
WifiGem is built for real-world maritime networks.
If your vessels rely on satellite connectivity and require a reliable, on-premises captive portal solution, WifiGem provides the performance, control, and privacy that maritime operations demand.
