Global mobile data traffic grew 2.6-fold in 2010, nearly tripling for the third year in a row Last year's mobile data traffic was three times the size of the entire global Internet in 2000. Global mobile data traffic in 2010 (237 petabytes per month) was over three times greater than the total global Internet traffic in 2000 (75 petabytes per month). Mobile video traffic will exceed 50 percent for the first time in 2011. Mobile video traffic was 49.8 percent of total mobile data traffic at the end of 2010, and will account for 52.8 percent of traffic by the end of 2011. Mobile network connection speeds doubled in 2010. Globally, the average mobile network downstream speed in 2010 was 215 kilobits per second (kbps), up from 101 kbps in 2009. The average mobile network connection speed for smartphones in 2010 was 1040 kbps, up from 625 kbps in 2009. The top 1 percent of mobile data subscribers generate over 20 percent of mobile data traffic, down from 30 percent 1 year ago. According to a mobile data usage study conducted by Cisco, mobile data traffic has evened out
