There are various aspects for radio communication systems in a rail environment. Today high attention is given to their operational aspects mainly for communication- based train control (CBTC for ATO/UTO). But there is surely a wider spectrum of different passenger services, security applications and further operational purposes where radio communication is very essential.

In the design of modern railway systems, passenger comfort and security also play an important role to improve the attractiveness of public transportation and to increase revenues. Balancing operator requirements, passenger demands, security needs and cost-effectiveness requires more than one data service on a common communication platform and makes a combination of passenger and operational data very attractive.

With the integrated TRainCom^® HST radio communication system, a variety of different data services can be handled simultaneously thanks to its broadband link character and its sophisticated Quality of Services (QoS) procedures.

TRainCom^® HST supports these services and provides mechanisms such as data integrity, data security, data prioritization, bandwidth allocation and quality of service procedures. In this way, TRainCom^® HST meets the high expectations of the operators and guarantees trouble-free operations.

Examples of operational data services:

• Communication-based train control (CBTC)
• Video surveillance (CCTV)
• Operational voice communication (VoIP)
• Passenger counting (APC)
• Online diagnostic data and condition monitoring (SCADA)
• Transportation management system (TMS)
