Wi-Fi networks will carry almost 60 percent of smartphone and tablet data traffic by 2019, reaching over 115,000 petabytes by 2019, compared to under 30,000 PB in 2015, representing almost 400 percent growth, according to Juniper Research.
With the caveat that usage is not revenue, value or sessions, that 60 percent figure indicates the amount of traffic a network operator might expect is carried on a Wi-Fi network rather than the core mobile network.
A few contestants--especially cable TV operators--might value more than others. as they have extensive backhaul networks that can be used to create dense residential public hotspot networks.
According to Wi-Fi service provider iPass, there were nearly 40 million community hotspots in 2014 and expects this to more than double this year to nearly 90 million.
Global mobile data traffic generated from devices including smartphones, feature phones and tablets forecast to exceed 197,000PB in 2019.
North America and West Europe will together account for over 50 percent of the global mobile data being offloaded in 2019, Juniper Research estimates.
Developing markets such as the Indian Subcontinent are forecast to witness higher growth rates and increased market share of the total mobile data traffic over the next five years. In fact, mobile operators in India already are seeing close to 100 percent year over year growth in data consumption.
