Wireless data traffic reaching monster proportions

Smart-phone use, mobile video drive data traffic into the exabyte range

NumeratorAs the use of smart phones and other mobile devices continues to explode, the amount of data winging wirelessly around the world likewise is growing exponentially. Wireless data analyst Chetan Sharma recently estimated that the average mobile user in the United States will consume 325 M of data per month, and that by the end of this year, total U.S. data traffic would exceed one exabyte, which is a billion gigabytes. That equates to about 50,000 years of DVD-quality video, according to the Wikipedia entry on exabytes.

Earlier this year, Cisco projected worldwide growth of mobile data traffic through 2014 in its Visual Networking Index, estimating that in two years, global traffic would exceed an exabyte each month and reach 3.6 exabytes a month, or 43.2 E per year, by 2014. Cisco's report said mobile video would be the biggest reason for the increase.
