Global Mobile Service Provider Data Migration Strategies

Offloading to Wi-Fi can help to transfer cellular mobile traffic by using complementary network technologies for the delivery of data. It enables mobile network operators to reduce the congestion in the cellular networks, while for the end-user it provides cost savings on data services and higher bandwidth availability.

It's now forecast that annual cellular data traffic -- generated by smartphones, media tablets, connected cars, and other M2M modules -- will reach 129,000 Petabytes (PB) by 2018 -- that's equivalent to approximately 14 billion hours of 4K ultra high-definition video streaming.

Mobile Data Market Development

According to the latest worldwide market study by Juniper Research, as 4K video content becomes more widely available, the average data usage will increase leading to almost threefold rise in cellular network traffic to exceed 318,000 PB by 2021.

This will put a significant pressure on mobile network providers who will see greater usage. Meanwhile, the monthly average revenue per user (ARPU) continues to decline, due to increased competition.


Mobile Data Traffic Forecast Highlights
  • Global average smartphone cellular data usage will reach 5GB per month by 2021, that's up from 2GB in 2017.
  • Global average tablet cellular data usage will exceed 3.3GB per month by 2021, up from 1.5GB in 2017.
  • Video will account for 60 percent of global mobile data traffic in 2017, before approaching 80 percent by 2021.
  • Traffic generated by cellular connected M2M systems will approach 6,000PB by 2021, dominated by the automotive sector.
  • Cellular-connected fixed devices including notebooks and eReaders will generate 20 percent of total traffic to the mobile networks in 2017.
  • Data traffic generated by smartphone, media tablets and feature phones will grow fourfold between 2017 and 2021 to reach 774,000PB; that's equivalent to 81 billion hours of 4K streaming.

Demand for Wi-Fi Offload Continues

The use of Wi-Fi technology by mobile operators for data offload has boosted the build-out of Wi-Fi hotspots in recent years. Juniper predicts that this will lead to over 60 percent of global mobile data traffic being offloaded via Wi-Fi networks in 2017.

However, the research findings also warned that a high QoE (quality of experience) while offloading data users will be essential for future network monetization strategies.

"Operators need to support a user-experience comparable to that of cellular. While progress has been made in refining hand-offs between cellular and Wi-Fi, there is still room for improvement by implementing better network management and planning tools, said Nitin Bhas, head of research at Juniper Research.

Digital Transformation Spending Reaches $1.8 Trillion

Ongoing investment in business technology will remain on track, despite concerns about the global economic outlook which continues to evolve in 2022. Enterprise CIOs and CTOs are focused on operational profitability and digital business growth goals that are enabled by strategic IT initiatives. Global spending on the Digital Transformation (DX) of business practices, products, and organizations is forecast to reach $1.8 trillion in 2022 -- that's an increase of 17.6 percent over 2021, according to the latest market study by International Data Corporation (IDC). Many anticipated DX investments will sustain this pace of growth throughout the 2021-2025 forecast period, with a five-year compound annual growth rate (CAGR) of 16.6 percent. Digital Transformation Global Market Development "IDC expects to see aggressive DX technology investment growth in 2022 following a minor slowdown during the pandemic period," said Craig Simpson, senior research manager at IDC .

Flexible Working: Why Company Culture Matters

The main reasons for the Great Resignation are obsolete leadership, fearful middle managers, and a toxic culture that hinders employee engagement. Perhaps that's why some organizations are still struggling with the consideration and development of a flexible working model.  They're incapable of evolving to a more enlightened approach to work where employees are treated with respect. They're stuck in a bygone era of the 20th-century industrial revolution where 'shareholder value' tops all other values, and where spreadsheets and financial data analysis drives all key decision making. We should not be surprised that 76 percent of human resource (HR) leaders now feel that hybrid work challenges an employee's connection to organizational culture, according to a recent survey by Gartner. A 2022 poll of HR leaders reveals the most challenging aspect of setting their hybrid strategy is adjusting the current organizational culture to support a hybrid workforce. In fact,

Energy Sector IoT Cybersecurity Gains Momentum

The electric distribution industry continues to invest in digital transformation projects. Advanced Metering Infrastructure (AMI) technology is becoming a driver for connected electricity meters, which will reach an installed base of 1.3 billion by 2027. AMI growth is prompting utilities and energy suppliers to revisit their IT infrastructure security and device management operations, according to the latest worldwide market study by ABI Research. Energy Infrastructure Security Market Development Digitization of traditional electricity grids and the modernization of the aging energy infrastructure is among the top concerns for utility operators and governments worldwide. Security for last-mile energy consumption applications was frequently overlooked. "However, the introduction of AMI, smart metering, and grid digitization is steadily increasing spending for secure management services, assisting implementers to transition to IT (information technologies) and OT (operational techno
