In 2019, the mobile data flow will be 10 times more than now.

The continued popularity of smart phones and the use of wearable devices will bring about substantial growth in mobile data usage. The forecast report released by network equipment giant CISCO shows that by the year 2019, the global wireless data traffic will increase to 10 times the current level.
CISCO's "visual network index" research forecast is partly based on the growth of wireless data traffic in 2014, and CISCO said last year the global wireless data flow reached 30 billion GB last year. CISCO analysts believe that if this growth trend continues, the global internet wireless data traffic will reach 292 billion GB by 2019.
What is the concept of 292 billion GB flow? It may be easier to understand: the equivalent of 23 photos per day on the earth and uploaded to the Instagram site for a whole year, so that the total number of photos is equivalent to about 65 trillion.
One of the key drivers of the massive growth of wireless data flows is the original growth of mobile users. The current global mobile data users are about 4 billion 300 million, and will increase to 5 billion 200 million by 2019. That is to say, about 59% of the world's 7 billion 200 million people now own mobile phones. By 2019, the total population of the world will increase to 7 billion 600 million, and the proportion of people who own mobile phones will increase to 69%.
In addition, there are 3 billion 200 million wireless devices for machine - machine communication, especially all kinds of wireless devices that share data with other machines in industrial and other commercial environments. This includes 578 million wearable devices, such as fitness tracker, wearable wireless camera and so on. CISCO believes that by 2019, the data usage of wearable devices will increase by 18 times, most of which will be transmitted by smart phones.
For operators, responding to the explosive growth of mobile data is a top priority. CISCO has put forward a strategy to transfer the wireless data traffic to the Wi-Fi network. Less than half (46%) of wireless data traffic was transferred to the Wi-Fi network last year, and this figure will increase to 54% by 2019. In addition, more than half of the voice calls will be completed through the Wi-Fi network.
In different regions, the annual growth rate of the mobile data use in the Middle East and Africa will reach 72%, the annual growth rate in Middle East Europe will also reach 71%, and the annual growth rate of North America is only 47%. However, in terms of flow, Asia is leading the world. By 2019, the flow of mobile data per month in Asia will be close to 10 billion GB, and the monthly flow of North America is close to 4 billion GB.
In the process of forecasting, CISCO combines analysts' independent reports, research on the scale of real world traffic, and its own prediction of the development trend of the wireless market. CISCO is the world's largest manufacturer of network equipment, providing products for Internet and wireless providers around the world.
