Video is expected to drive 83 percent of device-based data traffic in 2020 across 10 countries, according to PwC. That is a huge change from the pre-internet era, when voice services drove bandwidth consumption, as well as the PC era, when humans using PCs drove data traffic, or the early smartphone era, when internet web surfing drove traffic.

These days, it is video that dominates traffic volume, on both mobile and fixed networks, according to PwC.

Video already drives 70 percent of traffic, and will represent as much as 83 percent of all traffic by about 2020.

By 2020, perhaps 54 percent of mobile Internet connections globally will likely be high speed (delivering 30+ Mbps), while a further 42 percent will operate at medium speed (between 4 and 30 Mbps).
