Key Industry Highlights in the USA VoLTE and VoWi-Fi Coverage and User Base

Increasing Adoption of 5G-Enabled VoLTE Services

Voice over LTE (VoLTE) market is experiencing a significant transformation, due to the 5G networks and as the telecom operators are focused on investment into advanced infrastructure that it is helping for numerous advantages in terms of voice quality and low-latency communications.

The phasing out of 3G networks, mobile operators are focused on migrating to 5G VoLTE and this will help to ensure a smoother transition, featuring HD voice calling, VoNR (Voice over New Radio), and live video calling. Japan, South Korea and the USA among rapid VoLTE adopters as 5G coverage expands Cloud-native IMS (IP Multimedia Subsystem) solutions are also optimizing the scalability of VoLTE networks while lowering the operational costs while enhancing service reliability.

Expansion of Wi-Fi Calling for Indoor Connectivity

As Wi-Fi 6 and private 5G networks are being increasingly adopted, Voice over Wi-Fi(VoWiFi) is being recognized as an important solution for voice communication for indoor areas. Operators are deploying Wi-Fi calling per to cover weak signal spots at work places, underground metro stations as well as rural localities.

A VoWiFi feature liberates users from reliance on cellular signals, enabling calls on any Wi-Fi network and maintaining voice continuity. To provide cheap internal communications and better user experiences, enterprises are investing in carrier-grade Wi-Fi networks & devoting cloud-based VoWiFi solutions. This is quickly gaining momentum in smart home environments, IoT ecosystems and enterprise communication networks.

Rising Demand for High-Quality Voice Communication

Adoption of VoLTE and VoWiFi is propelled by the need for HD voice calling and enhanced call quality. Traditional circuit-switched networks are notorious for poor quality voice, delay, and dropped calls. Using packet-switched technology, VoLTE and VoWiFi provide low-latency, HD (high-definition) voice and reduced background noise.

They will be focusing on the development of IMS-based VoLTE solutions, which can be used to enhance voice reliability for enterprise customers along with remote workers and travellers. Moreover, VoWiFi offers a budget-friendly solution for international roaming, enabling customers to evade hefty roaming fees by transitioning to Wi-Fi-based calling during their travels abroad.

Expansion of IoT and Smart Devices with Voice Capabilities

The increase of smartphones, smart speakers, wearables, and IoT enabled devices is driving demand for VoLTE and VoWiFi connectivity. Seamless voice integration across multiple devices have become a concrete expectation of consumers, driving the - telecom providers to develop VoLTE-enabled IoT ecosystems.
