Mobile Providers Rally to Defend Voice Service Revenue

Mobile network service providers are focused on defending their traditional voice services from new market disruption that threatens to further erode their legacy business model. Armed with new technology and bold plans for more rapid deployment, savvy operators are responding to the incursion.

The number of VoLTE (Voice over LTE) connections is now anticipated to reach 2 billion by 2020, rising from an estimated 123 million in 2015, according to the latest worldwide market study by Juniper Research.

The research uncovered that the marked improvement in voice quality, enabled by VoLTE, is likely to spur increased adoption of the technology by mobile network service providers across the globe. Besides, given the downward trajectory of voice service revenue trends, wireless network operators must act swiftly to slow the decline.


Juniper found that direct revenues from VoLTE will likely be limited at first, with increased availability of compatible smartphones driving adoption of the HD (High Definition) voice technology. However, the network operator sense of urgency will become elevated as more non-traditional competitors enter the mobile voice services marketplace.

Mobile network operators will initially focus on experience and quality of service, rather than monetization. That being said, Juniper believes that failure to deliver a high quality offering at the outset could potentially result in subscriber churn to rival operators.

Mobile network operators, competing on quality of service, are also investing in voice over Wi-Fi calling (VoWi-Fi) -- aimed at tackling the internal network coverage issue.

The research found that operators are launching the VoWi-Fi service to add value for the customers with little extra investment, where VoLTE is focused more on operator network efficiency.

Formidable Competitor Enters the Global Arena

Juniper also claimed that to remain competitive, mobile network operators must quickly ensure that their voice communications offerings match those of the leading over-the-top (OTT) service providers.

They cited the example of Facebook Messenger, which launched 'free' HD VoIP call services over cellular and Wi-Fi networks. With this powerful competitor now threatening core voice service revenues, launching HD voice offerings will become a critical defense strategy for mobile network operators.

HD voice adoption has been steadily rising since 2009, with over 130 mobile network operators worldwide offering Mobile HD Voice. Juniper expects the number of capable devices to grow to over 1.3 billion by 2020, driven by more mobile handset manufacturers introducing new products.

Other key findings from the study include:

  • Far East and China will account for over 50 percent of the global VoLTE connections by 2020.
  • By 2020, VoLTE services could account for over $100 billion in annual service revenue.

Software-Defined Infrastructure: The Platform of Choice

As more organizations adapt to a hybrid working model for their distributed workforce, enterprise CIOs and CTOs are tasked with delivering new productivity-enabling applications, while also seeking ways to effectively reduce IT cost, complexity, and risk. Traditional IT hardware infrastructure is evolving to more software-based solutions. The worldwide software-defined infrastructure (SDI) combined software market reached $12.17 billion during 2020 -- that's an increase of 5 percent over 2019, according to the latest market study by International Data Corporation (IDC). The market grew faster than other core IT technologies. The three technology pillars within the SDI market are: software-defined compute (53 percent of market value), software-defined storage controller (36 percent), and software-defined networking (11 percent). "Software-defined infrastructure solutions have long been popular for companies looking to eliminate cost, complexity, and risk within their data cente

Digital Identity Verification Market to Reach $16.7B

As more enterprise organizations embrace the ongoing transition to digital business transformation, CIOs and CTOs are adopting new technologies that enable the secure identification of individuals within their key stakeholder communities. A "digital identity" is a unique representation of a person. It enables individuals to prove their physical identity during transactions. Moreover, a digital identity is a set of validated digital attributes and credentials for online interactions -- similar to a person's identity within the physical world. Individuals can use a 'digital ID' to be verified through an authorized digital channel. Usually issued or regulated by a national ID scheme, a digital identity serves to identify a unique person online or offline. Digital Identity Systems Market Development Complementary to more traditional forms of identification, digital identity verification systems can enhance the authenticity, security, confidentiality, and efficiency of
