The VNI offers forecasts each year and according to this year's update — covering the period 2017 to 2022 — mobile traffic will be on the verge of a zettabyte annually, which is 113 times more than all global mobile traffic in 2012.
The VNI update also forecasts that average global mobile speeds will increase from 8.7Mbps in 2017 to 28.5Mbps in 2022.
Cisco said by 2022, 5G connections were expected to make up more than 3% of the total mobile connections and account for about 12% of global mobile data traffic. By 2022, the average 5G connection was expected to generate about three times more traffic than the average 4G connection – 22GB a month, compared to 8GB.
