Networking experts are running out of superlatives to describe the coming tidal wave/explosion/cataclysm of mobile data traffic. Cisco last week said mobile data is expected to grow by 11 times in the next four years, reaching 18 exabytes per month by 2018. An exabyte is 1 billion gigabytes. Mobile data traffic is expected to grow by 61 percent annually into 2018, with the extra traffic from just one year—2017—expected to be triple the entire mobile Internet in 2013.
