Today's public transport passengers expect mobile and stable internet service. Free WiFi has become the norm in long distance bus and train travel and is also being increasingly introduced in local public transport. Flexible and reliable broadband connectivity and a good network infrastructure are the solid ground for implementing communications requirement such as passenger WiFi and infotainment, condition monitoring for vehicles or passenger information systems. Latest trends in communications technologies for public transport will be featured at IT-TRANS 2018. Around 250 exhibitors from more than 30 countries will present their products and solutions at the Karlsruhe Trade Fair Centre. The sixth edition of IT-TRANS, international conference and exhibition on intelligent urban transport, will take place from 6 to 8 March 2018.
