Growth Factors in the Voice Over LTE (VoLTE) Market:

• Enhanced User Experience

The VoLTE market is expected to grow as telco operators focus on customer experience with HD voice and lower call setup times. A simultaneous HD voice and data service provides a better customer experience when customers are multitasking across data, gaming, streaming and video conferencing. In developed markets, customers expect environments with high congestion to have low latency and reliability. Lower-cost 4G smartphones and data plans in developing markets have driven adoption there. Enterprises are adopting VoLTE for virtual meetings with good quality. Telecom operators have deployed AI-based quality monitoring, to ensure the best voice service quality in challenging and varying network conditions.

• Network Evolution & Efficiency

VoLTE is the first step in carrier modernization, with the replacement of 2G and 3G circuit-switched networks legacy with IP-based networks. VoLTE networks are efficient in spectrum and energy, maintain lower costs, provide better voice quality and capacity, and allow more high-quality simultaneous voice calls over the same network resources. Carriers in Asia-Pacific and Africa use VoLTE to extend the reach of voice services in remote areas. They are leapfrogging older technologies. Carriers in western markets expect that their networks will use energy efficiently and sustain themselves through green telecom initiatives, and VoLTE's improved efficiency and ability to scale make it a strategy for next-generation communications around the globe.

• Device & Roaming Interoperability

As more devices, and more countries, adopt support for VoLTE, lower-cost VoLTE devices such as smartphones, tablets, and wearables are making HD voice calls more accessible to the entire world. International roaming agreements allow calls across national borders. These agreements make the feature more useful for people who travel frequently. Telecoms are cooperating to reduce the latency as the user switches to another network. To expedite VoLTE registration, OEMs have begun preinstalling the profile onto new devices. VoLTE becomes a global standard together with a growing ecosystem of compatible devices and networks for next-generation mobile communications and interoperates across borders.

Key Trends in the VoLTE Market

• Growth of Cloud-Native VoLTE Deployments

The telecom industry is using more cloud-native architectures for building low-cost and scalable VoLTE solutions, and virtualized VoLTE cores allow carriers to manage resource allocations, traffic loads, and software updates more quickly and efficiently. It allows telecom operators to host VoLTE applications on a multi-tenant cloud architecture enabling flexibility and cost efficiency. Being cloud-native, VoLTE can integrate with other digital applications such as video conferencing platforms as well as AI-based voice analysis and translation applications in real time. With evolving 5G networks, VoLTE systems must be fully cloud-native so that ultra-reliable, low latency voice can be delivered.

• Emergence of AI-Powered Voice Quality Optimization

AI improves VoLTE performance management through real-time monitoring, call quality adjustment, and predictive analytics. AI algorithms can analyze huge network data sets to identify anomalies and predict potential congestion, thus improving VoLTE by adjusting routing dynamics for call stabilization. Voice quality analytics tools are providing better visibility to operators on customer experience metrics, as well as reducing network dropped calls and latency. Telecom operators are using AI-powered call noise suppression and echo cancellation technologies to provide solutions to solving call quality challenges in noisy environments. As networks become more complex, AI-driven automation has provided consistently high quality VoLTE services globally.

• Integration of VoLTE with Unified Communications Platforms

VoLTE is in active deployment as a component of unified communications and collaboration (UC&C) platforms, supporting voice and data communication across multiple devices. Interoperable, business solutions that tie voice calls, video and instant messaging are emerging as VoLTE is integrated within corporate communications platforms, including partnerships with telecom companies and UC vendors such as Microsoft Teams, Cisco Webex, Zoom and others. VoLTE is helping provide smooth mobility, with the ability to switch between a mobile and a corporate network. The evolution towards VoLTE/UC integration, however, will enable a new model to emerge, offering a more flexible, reliable, high-quality voice service for a global workforce.
