GSM-R 2W - Desktop

TrainTalk™ GSM-R - the system is approved as a 2W Cab Radio alternative for trains.

The TrainTalk system has been developed in collaboration with train operators in the Nordic region. The cost-effective 2W system can be used instead of the 8W train radio system, which makes use more flexible, faster and easier for train drivers and staff.

The railway industry can in many ways be regarded as a conservative industry, but they work very long-term and with well-proven reliable solutions such as GSM-R which will remain until at least 2030. It is a long process from idea stage to action.

TrainTalk™ on the other hand, is a flexible system. Even if new technologies in railway communication are added in the future, TrainTalk ™ can be upgraded and can thus, without any major difficulties and hassles, keep up with the development of the social and railway industry.

Cab Radio

The requirements for train radio systems are many and varied. Engine compartment, technical cabinet or cab - each installation site has its own conditions. The modular structure allows us to adapt Funkwerk's Cab Radio system to all kinds of different installations and interface requirements for our customers. Funkwerk's systems meet different protection classes depending on their intended use and specification. In order to withstand tough conditions on railway vehicles, great emphasis is placed on robustness, quality and reliability.

Antennas & cables

Train antennas are adapted for installation on the roof of railway vehicles which means very special conditions. The antennas must withstand very hard conditions such as rain, snow, hail and wind when the speed of some trains goes up to 300kmh. The antennas must also withstand a falling high-voltage line with 16000 V, so that the high voltage is not led into the train and injures people.

The transmission of the radio signals is at least as important, our train antennas correspond to very high demands on functionality in all frequency ranges from 380Mhz to 5.8Ghz. Several models have a built-in ground floor and can be installed on plastic surfaces such as fan covers or roofs that are made of fiberglass-reinforced plastic.
