How 5G Technology will Evolve Mobile Voice Services

The global mobile communication services market has always been prone to technological disruption and innovation. Over the past 10 years, however, the mobile voice services landscape has been profoundly affected by advances in new technology.

These include the penetration of artificial intelligence (AI) and machine learning in communication services, the rise of highly customized Over-the-Top (OTT) mobile voice and messaging applications, and the rollout of superior connectivity modes such as 4G LTE and 5G.

Mobile Voice Service Market Development

To adapt, mobile network operators are migrating their networks to an all-IP ecosystem. Focus has moved beyond Evolved Packet Core (EPC) frameworks to converge data and voice services on the same network.

In turn, this has created offerings such as Voice over LTE (VoLTE), Voice over Wi-Fi (VoWi-Fi) and HD Voice services. This has enabled mobile network operators to provide services that can compete directly with the OTT software app providers within the voice services marketplace.

According to the latest worldwide market study by Juniper Research, mobile network operator voice revenue will drop to $208 billion by 2024 from $381 billion in 2019, as users continue to prefer more flexible and free OTT voice services.


The new research forecasts that third-party OTT voice services will continue to grow -- nearing 4.5 billion users by 2024. The study found that while this trend will contribute to declining voice revenue for mobile network operators, 5G proliferation will propel a number of nascent mobile voice and video services.

Juniper now forecasts that incumbent mobile voice revenue could decline by 45 percent in 2024, due to an increase of 88 percent in third-party OTT mobile VoIP users over the next five years. That said, Juniper analysts urge telecom service providers to invest in AI-enabled communication platforms that facilitate competitive IP voice service delivery.

However, the research anticipates that improved 4G coverage and a growing number of capable devices will boost the number of mobile video call users; partially offsetting voice revenue losses. The study forecasts that Video over LTE (ViLTE) network operator revenue will exceed $33 billion by 2024.

Outlook for 5G Mobile Applications Growth

Moreover, Juniper anticipates that 5G deployment will generate new revenue streams for network operators by enabling innovative use cases for VoLTE and ViLTE. They believe that high data throughput and low latency will propel emerging services that have applications across a range of industries.

Additionally, network operators need to accelerate VoLTE launches, in order to benefit from emerging 5G services. The study notes that establishing a 5G-enabled IP Multimedia Subsystem (IMS) infrastructure for VoLTE will provide a foundation for future voice services rollouts, which network operators could monetize in the future.

Digital Transformation Growth Defies Market Volatility

The forward-looking CEO's commitment to ongoing investment in Information Technology (IT) is persistent. Worldwide IT spending is forecast to total $4.4 trillion in 2022 -- that's an increase of 4 percent from 2021, according to the latest worldwide market study by Gartner, Inc.   "This year is proving to be one of the noisiest years on record for CIOs," said John-David Lovelock, vice president at Gartner . Regardless, digital transformation remains a high priority across the globe. Geopolitical disruption, inflation, currency fluctuations, and supply chain challenges are among the many market volatility factors vying for attention, yet contrary to what Gartner saw at the start of 2020, enterprise CIOs are accelerating IT investments in 2022. Digital Transformation Market Development As a result, purchasing and investing preferences will be focused on areas including data analytics, cloud computing, seamless customer experiences, and IT security. Inflation impacts on

IoT Device Management Demand Gains Momentum

More forward-thinking CIOs and CTOs are focused on the adoption of the Internet of Things (IoT). Management challenges are top of mind for those who have already deployed a large number of sensors and associated network edge devices. Device management services are evolving in response to a greater breadth of new device technologies such as edge intelligence and related connectivity solutions, as well as the customer scalability and security of IoT deployments. But forward-looking suppliers are also preparing for a world where 41.3 percent of the connected devices will be using some form of Low Power Wide Area (LPWA) technologies by 2026. IoT Device Management Market Development Since IoT customers increasingly need to manage a larger fleet of connected devices, ABI Research now forecasts that IoT device management services will exceed $36.8 billion in revenues by 2026. Standardization is beginning to play a bigger role in device management services, as more connected devices use LPWA t

Anywhere, Anytime Workplace Demand for SASE

The ongoing adoption of flexible working models within the enterprise market has significant implications for typical IT organizations that must now support knowledge workers and front-line employees that operate outside the corporate network perimeter. The global COVID-19 pandemic created IT networking and security challenges. The expansion of the distributed workforce, an increasing reliance on cloud computing infrastructure, and the requirement to securely connect online employees -- wherever they choose to work, at any given moment in time. Legacy IT solutions that have rigid network underlays and a requirement for on-premises infrastructure cannot adequately deal with these trends. This 'Anywhere, Anytime Workplace' led to demand for new Secure Access Service Edge (SASE) solutions, with networking and security delivered as-a-service.
