The wireless data connection between the train and the outside world is made using the existing public cellular networks. In this case, the roof-top antennas communicate with the existing cellular network infrastructure and enable the transfer of data via routers to the communication systems on the train, to passengers and to the staff.
Different data communication channels (LTE / 4G) are enabled in the router using multiple SIM cards. The received data is bundled in the router and forwarded to the Ethernet backbone on the train. This enables significantly larger bandwidths to be transmitted in the train.
HUBER+SUHNER can supply robust antennas, flexible jumper cables, low-loss feeder cables, power splitters and multiplexes to create powerful communications solutions with railway-specific licences for installation in the train.

HUBER+SUHNER always supports the state of the art. The range of antennas is therefore already adapted to the new Long Term Evolution (LTE) standard (4G).
- 690 - 800 MHz (U.S.A.)
- 790 - 862 MHz (Europe)
- 2500 - 2690 MHz
This 3G technology, which is installed throughout many countries, enables higher data transmission rates than GSM/2G.
This 2G technology is still widespread but provides only low data transmission rates.
- 900 MHz
- 1800 MHz
- 1900 MHz
HUBER+SUHNER develops and produces robust, small form factor antennas for various industrial applications.
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.
