Trend Forecasting

This week, Cisco released its annual Visual Networking Index (VNI) forecast. On it, Cisco made some intimidating growth projections of the global data traffic growth. Let’s see…

According to Cisco, by 2019:

  • There will be 5.2 billion global mobile users, up from 4.3 billion in 2014
  • There will be 11.5 billion mobile-ready devices and connections, more than 4 billion more than there were in 2014
  • The average mobile connection speed will increase 2.4-fold, from 1.7 Mbps in 2014 to 4.0 Mbps by 2019
  • Global mobile IP traffic will reach an annual run rate of 292 exabytes, up from 30 exabytes in 2014
  • The overall mobile data traffic is expected to grow to 24.3 exabytes per month by 2019, nearly a tenfold increase over 2014.

However among these projections, VNI gave us hints of some interesting new trends that could soon change the way mobile networks are today.

VoWiFi is a trendy technology that has been getting the lights since the latest iPhone came out. But it is not just a new phone feature, it is actually a technology that has been around for a while, but the earlier solutions had several limitations that affected the adoption and ultimately the end-user experience.

However nowadays, and thanks to several enhancements that have been made, VoWiFi is a stable, reliable and secure solution. Because of it, there are already several MNOs that have recently launched or announced a launch of VoWiFi service.

In fact, according to the VNI, VoWiFi will surpass VoLTE in terms of minutes of use by 2018. By 2019, VoWi-Fi will have 53 % of mobile IP voice, up from less than a tenth of a percent in 2014. Which is actually funny, since the deployments of VoIP, or VoLTE started long time ago.

This data not only shows the big impact VoWiFi will have in the future, but also the how WiFi networks are becoming a crucial element of mobile cellular networks. By deploying a WiFi network, MNOs will not only be able to offload data traffic, but also, thanks to VoWiFi, operators will be able to deliver a cost-effective, scalable, and high quality indoor coverage, where cellular coverage is poor.

So all those operators who have been opposed to WiFi in the past, should better catch up!
