US Voice-over LTE (VoLTE) Market Analysis

The US Voice-over LTE Market size is estimated at USD 20.80 billion in 2024, and is expected to reach USD 148.46 billion by 2029, growing at a CAGR of 48.14% during the forecast period (2024-2029).

Voice over LTE (VoLTE) technology has enhanced voice communication by transmitting voice calls over the LTE/4G network, offering superior voice quality and more efficient network use compared to traditional circuit-switched methods. The widespread deployment of LTE networks drives the VoLTE market, the ongoing transition to 5G, and the increasing demand for high-quality voice services in the United States.

• According to Ericsson, 5G adoption in North America witnessed immense growth, with 260 million subscriptions by the end of 2023. Fixed Wireless Access (FWA), which provides high-speed internet to homes and small businesses, remains the primary technology driving fixed broadband growth. 5G is also expanding in the enterprise segment, supporting wireless Wide Area Networks (WAN) for branch office locations and serving mobile professionals. By 2029, it is projected that there will be around 430 million 5G subscriptions, accounting for 92% of all mobile subscriptions.
• The rise of 5G necessitates the phasing out of existing 2G and 3G networks. There are plans to repurpose their spectrum for more advanced services. To facilitate this transition, the US telco industry is exploring alternatives to traditional 2G/3G services, particularly circuit-switched voice calls. VoLTE and VoLTE roaming services are pivotal substitutes. Embracing VoLTE not only replaces outdated voice services but also streamlines network operations, paving the way for enhanced efficiency and the deployment of spectrum in innovative 5G applications.
• A National Spectrum Strategy that includes a spectrum pipeline for 5G, 6G, and beyond is critical to maintaining US wireless leadership and US technological and economic security. US conformance with globally harmonized band allocations can strengthen US leadership in the global telecommunications ecosystem. It is recommended that 1.5-2.2 gigahertz of additional wideband spectrum is needed in suitable mid-band frequencies that can be repurposed for commercial networks. VoLTE offers greater spectrum efficiency than both GSM and WCDMA, meaning that spectrum utilization can be optimized by network operators so more traffic can be carried.
• The convergence of voice-over LTE (VoLTE) with the Internet of Things (IoT) represents an emerging trend with significant implications for the industry. VoLTE integration can enhance IoT applications by offering high-quality voice interaction capabilities for devices requiring two-way communication, such as security systems and medical alert devices.
• In industrial settings, voice-over LTE (VoLTE) facilitates reliable machine-to-machine (M2M) communication, enabling the monitoring and control of machinery and processes. This leads to enhanced operational efficiency and safety measures. The integration of Internet of Things (IoT) technology has brought about a revolution in various industries, particularly manufacturing, giving rise to the concept of Industrial IoT (IIoT). IIoT is transforming manufacturing plants by connecting intelligent devices through Supervisory Control and Data Acquisition (SCADA) systems, leading to the establishment of fully digitalized facilities. VoLTE systems play a crucial role in providing wireless connectivity and transmitting data in real time. The United States is experiencing growth in smart and connected factories.
