A dedicated Wi-Fi network is built along tracks to provide reliable broadband wireless networks between trains, stations and along the trackside. This ensures a robust broadband connection to the train.
Components on board
The Wi-Fi signal is converted from the roof-top antenna using a communication gateway and distributed in the form of an Ethernet signal, for example to the various Wi-Fi access points in the train.
Technical approaches to increasing the data rate:
- Roof-top antennas
- Flexible jumper cables
- Low-loss feeder cables
- Use of MIMO (Multiple Input Multiple Output) technology
- Communication using various frequency ranges:
- Wi-Fi: 2.4 and 5 GHz
- WiMAX: 2.6 GHz
- Other ISM bands
- Other local frequency ranges
|Use of MIMO technology
||Directional versus omni-directional antenna
||Use of SPOT antennas at the front of the vehicle
HUBER+SUHNER supplies all the passive components
required to establish the trackside Wi-Fi network:
- Radio frequency cables
- Power splitters
- Earthing clamps
- Lightning protectors
- Fiber optic cable systems
- Fiber management
Antennas for Connected Mobility
HUBER+SUHNER develops and produces robust, small form factor antennas for various industrial applications.
Pre-assembled, ready to connect: Assemblies and cable systems from HUBER+SUHNER guarantee the rapid and safe installation of reliable connections - even in the field. These solutions are used for a range of different indoor and outdoor applications.
HUBER+SUHNER offers a wide range of fiber optical cables, optimised for fix or mobile applications at indoor and outdoor areas. Due to new market demands innovative products are developed and tested in accordance with international standards, which fulfil high mechanical and thermal conditions as well as fire requirements.
HUBER+SUHNER is offering various antennas for trains and buses that transmit signals perfectly within the vehicle and along the track.
Some products cannot be allocated in any of the three main lines. They are consolidated in the speciality cable line. It includes special designs like odd impedance, twinax or triax cables. A selection of low-noise coax and triax cables is also available. Cables with special qualification, for instance in accordance with railway norms like EN 45545 or in accordance with UL are also listed in this section.
