Mobile video traffic accounted for 60 percent of total mobile data traffic, according to Cisco. By 2021, 78 percent of the world’s mobile data traffic will be video by 2021.
You might think that suggests coming 5G networks are mostly of value to mobile operators as a way of supplying much more bandwidth to support extensive video consumption. In fact, 5G will be built on changes across the network, from network cores, which are more virtualized, to supported applications (more machine-to-machine apps).
The most-important categories of applications and revenue streams supported by the coming network might in fact not require the huge amounts of new bandwidth at all. That is why many expect overlay low-power, low-bandwidth networks to be important in the 5G era.
The coming network likely also will be the first to use big data and artificial intelligence to manage networks and services.
