Global Mobile Data Traffic will Reach 197,000 Petabytes

Mobile internet traffic continues to grow at an unprecedented pace across the globe, driven primarily by video usage. The increase in mobile subscriptions, smartphone usage and software app availability have resulted in significantly more data traffic per mobile device user.

Traffic offloading helps in moving mobile data from one network to another, by using complementary wireless network technologies -- such as Wi-Fi hotspots -- for the delivery of data via cellular networks.

Offloading enables mobile network operators to reduce the congestion in their cellular networks, while for the end-user it provides cost savings on data services and higher bandwidth availability.

Wi-Fi networks are forecast to carry almost 60 percent of smartphone and media tablet data traffic by 2019, reaching over 115,000PB (Petabytes) by 2019 -- that's compared to under 30,000PB in 2015, representing almost a four-fold increase.

According to the latest worldwide market study by Juniper Research, mobile data offload -- i.e. traffic migration from a mobile cellular network to a Wi-Fi network -- offers several key benefits to industry stakeholders.


Offload not only addresses the issue of patchy cellular wireless coverage, but also has the potential for the creation of new services such as voice over Wi-Fi, and to increase the usage of existing 3G or 4G services.

However, the research cautioned that Wi-Fi offload brings challenges to mobile network operators of effective deployment and return on investment.

"Operators need to deploy their own Wi-Fi zones in problematic areas or partner with Wi-Fi hotspot operators and established aggregators such as iPass and Boingo," said Nitin Bhas, head of research at Juniper Research.

Additionally, operators are also converting residential customers to community hotspot providers, especially in the U.S. market. 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.

Other global mobile data traffic highlights include:
  • Global mobile data traffic generated from devices including smartphones, feature phones and media tablets is forecast to exceed 197,000PB in 2019.
  • Juniper estimates global smartphone data consumption to be nearly twice the amount of tablet traffic in 2015.
  • 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 5 years; with operators in India already witnessing close to 100 percent y-o-y growth in data usage.
  • North America and West Europe will together account for over 50 percent of the global mobile data being offloaded in 2019.

Why Healthcare and Smart City Apps Drive 5G IoT

Fifth-generation (5G) wireless technology for cellular networks is a successor to fourth-generation (4G) wireless technology. By 2023, Juniper Research anticipates that there will be over 1 billion 5G connections globally. The technology will provide the data infrastructure for the advancement of wireless communications and for new developments in the Internet of Things (IoT) -- including smart cities and healthcare. 5G IoT Market Development According to the latest worldwide market study by Juniper Research, 5G IoT connections will reach 116 million globally by 2026 -- that's increasing from just 17 million connections in 2023. Juniper analysts predict that the healthcare sector applications and government or other smart city services will drive this outstanding 1,100 percent growth over the next three years. Juniper examined 5G adoption across key industry sectors -- such as the automotive, mobile broadband, and smart homes -- and forecasts healthcare and smart cities will accoun

How Savvy Leaders Re-Imagine Work in 2023

As we look to the year ahead, there will be significant challenges and opportunities facing the Chief Human Resource Officer (CHRO) role. In order to be successful, savvy HR leaders must be prepared to take proactive steps that adapt and evolve.

HR Innovation Market Development One of Gartner's key predictions for 2023 is that the use of artificial intelligence (AI) and automation will continue to increase within the enlightened digital workplace. This transition will require HR leaders to develop new skills and competencies in order to effectively manage and lead teams that are increasingly relying on these enabling technologies. Additionally, HR leaders will need to ensure that their organizations are investing in the necessary infrastructure and re

Top 10 CFO Priorities Require Rethinking Finance

The Chief Financial Officer (CFO) role is essential to digital business growth. While CFOs do not get closely involved in the tactical details of the digital transformation of their functions, they still recognize its strategic importance. According to the latest survey by Gartner, CFOs are faced with the challenge of balancing the need for substantive digital business innovation with financial cost control and risk management. "CFOs will be stretched thinly across many activities in 2023. The survey revealed a wide range of actions CFOs plan to either lead or be significantly involved with," said Marko Horvat, vice president at Gartner. Survey Findings: The Top Ten Priorities Cost Optimization - Cost reduction remains the top priority for CFOs as they look for ways to cut costs and improve efficiency in their operations. This includes identifying cost-saving opportunities through automation, outsourcing, and business process improvement. Business Continuity - The global C
