Majority of mobile data traffic to offload to Wi-Fi networks by 2019
However, the research 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.
The research, 'Mobile Data Offload & Onload: Wi-Fi, Small Cell & Network Strategies 2015-2019', 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 eight times between 2014 and 2019," adds 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 to 3 years.
In 2014, data traffic generated by smartphones, feature phones and tablets in the Far East & China exceeded that of North America for the first time.
Demand for Wi-Fi
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.
Other key findings include:
- • Onloaded M2M traffic will 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.
