TELEFUNKEN - Radio Communication Systems

Based on its long tradition in railway communications, with several thousand analogue radios deployed throughout Europe, TELEFUNKEN has developed a new class of broadband radio systems for various rail applications.

We provide a complete range of dedicated products under the registered TRainCom® brand, offering outstanding performance in radio communication for all types of rail systems and a variety of passenger and operational data services.

BROADBAND DATA TRANSMISSION FOR RAIL APPLICATIONS

The combination of TELEFUNKEN radio communications technology, state-of-the-art network design and proven network technology is the basis of all TRainCom® integrated radio systems.

Complemented by fast handover mechanisms, complex network scenarios supporting seamless data transmission to and from multiple vehicles can be reliably implemented.

MULTIPLE DATA SERVICES FOR PASSENGERS

Multiple data services for passengers and for operational purposes can be provided simultaneously, securely and without any interference to the microwave radio link of a TRainCom® system.

Customers can choose between licensed and unlicensed frequency band designs; the TRainCom® system can also be adapted to customer-specific frequencies.

According to the specific requirements of each rail application, TRainCom® systems are available as TRainCom® MT or TRainCom® HST.

TRAINCOM MT – NETWORK COVERAGE FOR TRAINS

Designed to meet the classical requirements of Communication-Based Train Control (CBTC) and Automatic Train Operation (ATO) in mass transit or metropolitan rail applications, TRainCom® MT systems offer wide flexibility and scalability to realise integrated communications solutions for increasing communications demands.

High reliability and system availability for hard operational requirements, as well as passenger services and public safety measures such as realtime video surveillance (CCTV), are all made possible via a broadband data link offering up to 16Mbps (16Mbps per up and down-link).

Regardless of whether the track is in the open, elevated or completely in-tunnel, TRainCom® MT is the right choice to achieve full rail network coverage for passenger intercom and Passenger Information Systems (PIS), CCTV and CBTC.

TRainCom® HST – BROADBAND AND FULL-DUPLEX LINK FOR TRAINS

Increasing demand for passenger communication services, particularly among business travellers, and ever-increasing security requirements, especially in high-speed train applications, are among the main factors that led to the dedicated TRainCom® HST systems.

Based on quick handover mechanisms, TRainCom® HST systems can maintain a continuous data link between trackside radio base stations and vehicles running at speeds up to 500km/h.

This broadband and full-duplex link of up to 16Mbps (16Mbps per up and down-link) supports all IP-based data services and can enable new options in train diagnostics and maintenance, passenger entertainment, and online ticketing applications.

RADIO COMMUNICATION FOR MASS TRANSIT AND HIGH SPEED TRAINS

TRainCom® train radio communication systems include features such as:

• High data rates of up to 16Mbps (16Mbps per up and down-link)
• Full duplex radio transmission
• Full IP-based system
• Licensed, unlicensed and customer-specific frequency bands
• Seamless and lossless handover mechanisms
• High reliability and system availability up to 99.99%
• Scaleable and modular system design
• Integrated communication system with multiple data services
• Quality of Service (QoS) features
• High data security and integrity
• Built-in radio system diagnosis (SNMP)

One of the first applications of these radio systems was the challenging ultra-highspeed Transrapid MAGLEV train system. During its daily commercial service in Shanghai, TELEFUNKEN radio systems facilitate operational data transmission, provide for absolute communications reliability, and deliver high performance even at speeds above 500km/h.
