Since January 1, 2017, free WLAN has been available to all passengers on Deutsche Bahn's ICE trains - in both 1st and 2nd class. By providing parallel access to all mobile networks, Deutsche Bahn ensures a strong, fast and stable network, which it says is the "best mobile WLAN system available on the market today". The transport operator is thus upgrading to meet the needs of its customers, because according to a survey by Radiozentrale, 46.3% of respondents would like to use their smartphone more often while on the move (source: statista.com). In recent years, the number of mobile Internet users has risen rapidly from just 20% in 2011 to 68% in 2016 (source: ZDF, ARD, via statista.com).
