Mobile data traffic is set to approach almost 197,000 Petabytes (PB) by 2019, equivalent to over 10 billion Blu-ray movies, according to Juniper Research.

However, the research found that only 41 per cent 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.

While 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.

Research author, Nitin Bhas, said video was forming an ever-greater proportion of network traffic.

"For example, Juniper Research anticipates that video traffic over smartphones will increase by nearly eight times between 2014 and 2019," he said.

"Video currently accounts for around 60 per cent of global IP traffic and, in some developed markets, this proportion is likely to exceed 70 per cent in 2-3 years."

In 2014, data traffic generated by smartphones, 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.

The study also found onloaded M2M traffic would significantly increase over the forecast period, primarily driven by telematics and connected car infotainment systems.

North America and Western Europe will have the highest offload factor throughout the forecast period.
