KVH TracNet Hub H30 DC BDU: Complete Guide
Meta title: KVH TracNet Hub H30 DC BDU – Complete Guide | Global Satellite Group
Meta description: Learn how the KVH TracNet Hub H30 DC BDU manages satellite, cellular, and shore Wi-Fi connectivity for a reliable onboard network.
Overview
The KVH TracNet Hub H30 DC BDU is the below-deck network control unit used with the KVH TracNet H30 hybrid connectivity system.
It acts as the central point of control for the vessel’s communications network, bringing together satellite connectivity, cellular service, and shore-based Wi-Fi. The Hub then distributes the available connection to onboard users and equipment through Wi-Fi, Ethernet, and VoIP.
Designed for marine installations, the DC-powered Hub provides a compact and flexible solution for yachts, leisure vessels, commercial vessels, workboats, and offshore operations.
What Does the TracNet Hub Do?
The TracNet Hub is the intelligence behind the onboard hybrid network. Its main role is to manage available Internet sources and help deliver the most appropriate connection for the vessel’s location and operating conditions.
The Hub supports three primary connectivity options:
- Shore Wi-Fi when the vessel is in a marina or alongside a dock
- Cellular connectivity when suitable mobile coverage is available near shore
- Satellite connectivity when the vessel is operating offshore
Depending on configuration, connection availability, service cost, and data quality, the TracNet system can select the most suitable available network option.
This allows the vessel to maintain a consistent onboard network while making efficient use of terrestrial connectivity whenever it is available.
Key Features
Hybrid Network Management
The Hub is part of the KVH ONE hybrid network architecture. It helps manage the transition between Wi-Fi, cellular, and satellite services, supporting continuous connectivity from the marina to offshore waters.
DC Marine Power
The H30 DC BDU operates from a 10-30 V DC power source. This makes it suitable for marine electrical systems commonly found on 12 V and 24 V vessels.
Built-In Wi-Fi Router
The unit includes a built-in Wi-Fi router to distribute connectivity to onboard devices, including:
- Smartphones and tablets
- Laptops and workstations
- Crew devices
- Guest devices
- Compatible onboard networked equipment
Ethernet LAN Connectivity
Integrated Ethernet LAN interfaces allow the Hub to connect to fixed onboard equipment and network infrastructure, such as:
- Vessel routers and switches
- Computers and workstations
- Entertainment systems
- Operational and business systems
- Compatible communications equipment
User-Supplied SIM Access
The Hub provides access for a user-supplied SIM card, allowing the vessel to use a selected cellular service when coverage is available.
This can be particularly useful in marinas, ports, coastal routes, and nearshore operating areas.
VoIP Support
The TracNet Hub supports one VoIP line, enabling compatible IP voice services to be integrated into the vessel’s communications network.
Hybrid Connectivity Architecture
The TracNet Hub receives and manages data from several possible wide-area network sources.
Shore Wi-Fi
Shore Wi-Fi can be used when the vessel is at a marina, berth, or dock with a compatible available network.
Benefits may include:
- Reduced use of satellite data
- Improved access for software updates and large downloads
- Convenient connectivity for crew and guests in port
Cellular Service
Cellular service can be used when the vessel is within suitable mobile coverage. This is commonly relevant during coastal navigation and port calls.
Benefits may include:
- Efficient nearshore connectivity
- Flexibility to use local or regional SIM services
- Reduced reliance on satellite service when terrestrial coverage is available
Satellite Service
Satellite connectivity provides the essential offshore connection when shore Wi-Fi and cellular coverage are unavailable.
It supports communications and data services during offshore navigation, remote operations, and long-distance passages.
Vessel Network Distribution
Once the Hub has an active Internet source, it distributes the connection to the vessel’s local network through:
- Wi-Fi
- Ethernet LAN
- VoIP
