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."

The $150B Race for AI Dominance

Two years after ChatGPT captured the world's imagination, there's a dichotomy in the enterprise artificial intelligence (AI) market. On one side, technology vendors are making unprecedented investments in AI infrastructure and new feature capabilities. On the other, there's measured adoption from customers who carefully weigh the AI costs and proven use case benefits. Artificial Intelligence Market Development The scale of new investment is significant. Cloud vendors alone were expected to invest over $150 billion in capital expenditures in 2024, with AI infrastructure being the primary driver. This massive bet on AI's future is reflected in the rapid growth of AI server revenue. Looking at just two major players - Dell Technologies and HPE - their combined AI server revenue surged from $1.2 billion in Q4 2023 to $4.4 billion in Q3 2024, highlighting the dramatic expansion. Yet despite these investments, the revenue returns remain relatively modest. The latest TBR resea...
