Mobile data traffic, generated by smart phones, feature phones and tablets will approach almost 197,000 PB (Petabytes) by 2019, equivalent to over 10 billion Blu-ray movies, according to Juniper Research (www.juniperrsearch.com).

However, the research group found that only 41% of the data generated by these devices will be carried over cellular networks by 2019, with the majority of mobile data traffic offloaded to Wi-Fi networks. Juniper Research estimates that the average monthly data usage by smartphone and tablet users will double over the next four years. The daily media consumption by mobile users will continue to rise, bolstered by the rise in 4G adoption and factors such as HD video usage.

“"Certainly, video is forming an ever-greater proportion of network traffic. For example, Juniper Research anticipates that video traffic over smartphones will increase by nearly 8 times between 2014 and 2019," says research author Nitin Bhas.

Video currently accounts for around 60% of global IP traffic and, in some developed markets, this proportion is likely to exceed 70% in 2-3 years. In 2014, data traffic generated by smart phones, feature phones and tablets in the Far East and China exceeded that of North America for the first time.

Additionally, the research observed that Wi-Fi has now become an integral part of operators’ network strategy. Wi-Fi is not just being used for data offload, but also to maintain call connection quality in challenging network topologies. For example, EE UK launched its Wi-Fi calling feature on a selected number of handsets in April 2015.
