Smartphones and other mobile devices will flood the Internet with data in the next years. Cisco Systems this week announced its forecast that the data traffic from cellular networks will increase eight times by 2020, reaching 366.8 exabytes of the 44.2 exabytes in 2015, writes Wall Street Journal.One exabyte is equal to one quintillion bytes or one billion gigabytes. 366.8 exabytes equivalent of publication of 7 trillion video on YouTube, stating Cisco.
Even in this volume mobile traffic represents just 15% of the total data traffic by 2020 compared to 5% in 2015. But it will grow at a faster rate than the Internet as a whole, the company says.
Cisco sees multiple growth drivers of mobile data. At the head of this list stands video - as well as the number of videos that are generated by smartphones and the growing demand for high-quality images that require greater data traffic.
One of the important factors for the increase in traffic would be the spread of the basic technologies. Cisco expect the number of mobile users to grow and to reach 5.5 billion in 2020, or 70% of the world population, comparing to 4.8 billion in 2015. This will be more than the number of people with electricity (5.3 billion) or bank accounts (4.5 bln.), according to Cisco.At the same time many people have more than one mobile device - especially smart watches and other portable devices, which start to communicate with each other, sometimes without the need for user intervention. Cisco indicates that the number of connected mobile devices will grow from 7.8 billion in 2015 to 11.6 bln. in 2020.
Shruti Jain, senior analyst at Cisco, says that one of the most surprising trends in new studies of the company is how fast mobile data traffic will shift to the fourth generation (4G) networks that transfer data faster than 3G networks popular at the moment.
By 2020, such networks can handle connections of 40.5% of the mobile devices, which is much above the 14.5 percent in 2015.
