By 2021, the total number of smartphones (including phablets) will be over 50 percent of global devices and connections (6.2 billion) — up from 3.6 billion in 2016, according to the 11th annual Cisco Visual Networking Index™ (VNI) Global Mobile Data Traffic Forecast (2016 to 2021).
“With the proliferation of IoT, live mobile video, augmented and virtual reality applications, and more innovative experiences for consumer and business users alike, 5G technology will have significant relevance not just for mobility but rather for networking as a whole,” said Doug Webster, vice president of service provider marketing. “As a result, broader and more extensive architectural transformations involving programmability and automation will also be needed to support the capabilities 5G enables, and to address not just today’s demands but also the extensive possibilities on the horizon.”
Some highlights of the report:
1. Rise in global mobile data center traffic
- By 2021, global mobile data traffic will reach 49 exabytes per month or 587 exabytes annually).
- The forecast annual run rate of 587 exabytes of mobile data traffic for 2021 is equivalent to:
- 122 times more than all global mobile traffic generated just 10 years ago in 2011
- 131 trillion images (e.g., MMS)
2. High growth for live video on mobile
- Mobile video will increase 8.7-fold from 2016 to 2021 and will have the highest growth rate of any mobile application category. Mobile video will represent 78 percent of all mobile traffic by 2021.
- Live mobile video will grow 39-fold from 2016 to 2021. Live mobile video will represent 5 percent of total mobile video traffic by 2021.
3. Growth in Virtual Reality (VR) and Augmented Reality (AR)
- VR immerses users in a simulated environment. AR is an overlay of technology on the real world.
- Applications such as virtual reality (VR) are adding to the adoption of wearables such as headsets. VR headsets are going to grow from 18 million in 2016 to nearly 100 million by 2021— a fivefold growth.
- Globally, VR traffic will grow 11-fold from 13.3 petabytes/month in 2016, to 140 petabytes/ month in 2021.
- Globally, AR traffic will grow 7-fold between 2016 and 2021, from 3 petabytes/month in 2016 to 21 petabytes /month in 2021.
4.Global connected wearable devices driving M2M growth
- Cisco estimates there will be 929 million wearable devices globally, growing nearly threefold from 325 million in 2016.
- Globally, the number of wearable devices with embedded cellular connections will reach 69 million in number by 2021—up from 11 million in 2016.
5. Mobile data traffic offload to Wi-Fi networks
- In 2016, 60 percent of total mobile data traffic was offloaded; by 2021, 63 percent of total mobile data traffic will be offloaded.
- In 2016, monthly offload traffic (10.7 EB) exceeded monthly mobile/cellular traffic (7.2 EB).
- Globally, total public Wi-Fi hotspots (including homespots) will grow six-fold from 2016 (94.0 million) to 2021 (541.6 million).
- Wi-Fi traffic from both mobile devices and Wi-Fi-only devices together will account for almost half (49 percent) of total IP traffic by 2020, up from 42 percent in 2015.
6.Regional mobile data traffic growth (2016 – 2021)
- The Middle East and Africa will have 12-fold growth
(2016: 7.3 exabytes/year; 2021: 88.4 exabytes/year) - Asia-Pacific will have 7-fold growth
(2016: 37.3 exabytes/year; 2021: 274.2 exabytes/year) - Latin America will have 6-fold growth
(2016: 5.4 exabytes/year; 2021: 34.8 exabytes/year) - Central and Eastern Europe will have 6-fold growth
(2016: 11.1 exabytes/year; 2021: 63.0 exabytes/year) - Western Europe will have 6-fold growth
(2016: 8.8 exabytes/year; 2021: 50.3 exabytes/year) - North America will have 5-fold growth
(2016: 16.9 exabytes/year; 2021: 76.8 exabytes/year)
