How VoLTE Subscribers will Reach 3 Billion by 2021

Typically, VoIP is voice traffic that's carried over the public Internet. The launch of 4G LTE, and wireless hotspots in major cities around the globe, has brought about a downward trend in traditional switched telecom network activity.

VoIP is more efficient than PSTN, and technology improvements in these areas have been instrumental in allowing VoIP to spread to the mobile environment.

Market Development for VoIP Apps

Juniper Research has revealed that the number of Voice over LTE (VoLTE) subscribers will rise from 488 million in 2016 to 3 billion in 2021, as network operators reap the benefits from widespread 4G infrastructure roll-outs.

According to the Juniper assessment, there are now 165 operators in 73 countries investing in VoLTE, including 102 operators that have commercially launched an HD voice service using VoLTE in 54 countries.

The market study found that the number of users adopting VoLTE services will likely overtake subscribers of Over-the-Top voice app services, popularized by applications such as Messenger, WhatsApp and WeChat, for the first time by 2021.


Consequently, the mobile data traffic attributable to VoLTE will rise significantly over the next 4 years, representing a seven-fold rise from 2,000 Petabytes in 2016.

The research found that operators will introduce widespread national and international VoLTE roaming, as VoLTE usage rises to over 10 trillion minutes by 2021, equivalent to around 3.3 trillion music tracks.

It argued that it is imperative that traditionally slow-moving operators enter partnerships with platform vendors in order to accelerate service launches.

Juniper predicted that operators will be eager to enter partnerships to maintain their quality of service, rather than downgrade calls to circuit-switched telephony, while roaming.

Outlook for New VoLTE Applications

As such, operators who fail to undergo a shift in attitudes to VoLTE risk losing ground to competitors, and increasing user churn.

"Operators have historically used service coverage as a differentiation point; selling the notion of always available," said Sam Barker, analyst at Juniper Research. "The depth and breadth of high-quality voice services will now serve to enrich that offering and entice users: always available, always best-in-class."

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
