Of the 19 markets covered, while smartphone usage is a key driver for data traffic growth, fixed broadband still accounted for the largest share of data traffic in 2016. With much consumption still happening within the home rather than on the move, fixed broadband will continue to account for the largest share of data traffic until 2020, when smartphones will exceed fixed broadband for the first time
The US and China dominance that we witnessed in 2016 will continue through 2021, with the two countries together accounting for 49% of all data traffic. China will see more rapid growth, at a 26.2% CAGR compared to the US at a 19.8% CAGR. However, the US will remain the largest data market throughout this period.
