4G data traffic has started to dominate total traffic consumption in 2015 and annual global 4G data usage is expected to exceed 224.7 Exabytes in 2020. According to ABI Research, this will equate to 79 per cent of total data traffic. The research company noted that mobile operators are sparing no effort to migrate customers to 4G networks through new favourable tariff plans, and convenient and quick update services. It added that richer content services including HD video, lossless music, and high-speed games are in great demand, boosting data service revenues. Furthermore, the gap between 4G and 3G monthly ARPU will widen over the period 2014 to 2020. Competition will drive down ARPU for mobile operators, but 4G ARPU will hold up better as a result of the higher data consumption stimulated by 4G users. Release
