IoT is revolutionizing industries by enabling seamless communication between devices. While data and SMS have traditionally been the foundation of IoT connectivity, voice communication is now emerging as a powerful tool for real-time interaction. With a growing range of secure and cost-effective voice solutions available, IoT deployments are benefiting from enhanced global connectivity.

How IoT is Enhancing Voice Communication

IoT is playing a crucial role in revolutionizing voice communication by providing enhanced connectivity, scalability, and intelligence. Here are some ways that IoT is improving voice solutions:

Seamless Connectivity: IoT-backed voice solutions leverage multi-network capabilities to ensure constant and reliable communication.
AI-Driven Automation: IoT-powered voice assistants and predictive analytics can enhance customer support, healthcare monitoring, and industrial automation.
Enhanced Security: Secure voice data transmission and whitelisting prevent unauthorized access, making IoT-driven voice solutions more reliable.

What are the different types of Voice in IoT?

Voice communication in IoT can take multiple forms, each catering to different use cases. Some of the most common types include:

Voice over IP (VoIP): A technology that enables voice communication over the internet rather than traditional phone lines. VoIP is highly flexible and is widely used in IoT applications such as smart intercoms and remote healthcare devices.

Voice over LTE (VoLTE): This allows voice calls to be carried over 4G LTE networks rather than legacy circuit-switched networks. VoLTE ensures higher-quality voice communication, lower latency, and better reliability for IoT applications like smart security systems and emergency response devices.

Voice over WiFi (VoWiFi): With VoWiFi, voice calls are transmitted over WiFi networks instead of cellular connections. This is particularly beneficial in areas with poor cellular coverage, making it an ideal solution for industrial IoT environments and remote monitoring systems.

Traditional voice (analogue): Traditional voice calls use circuit-switched networks and are typically found in legacy systems. While less common in modern IoT solutions, some industrial and emergency response applications still rely on analogue voice communication.

When Traditional Voice Calls Are Not Supported in IoT

Analogue voice communication depends on circuit-switched networks, which do not always align with the infrastructure and requirements of IoT devices.

Most IoT networks prioritize low-power, high-efficiency communication over traditional voice, which is why standard mobile voice services are often not feasible for IoT applications.

However, IoT-backed voice solutions, such as VoLTE, VoWiFi, and SIP-based communications, offer a viable alternative. These technologies allow IoT devices to make voice calls over data networks rather than traditional telephony infrastructure, ensuring greater flexibility, cost-effectiveness, and reliability for real-time voice communication.

When Voice is Not Supported in IoT: NB-IoT

While voice communication is essential for many IoT applications, it is not always supported. One key example is Narrowband IoT (NB-IoT), which is governed by the 3GPP standard. NB-IoT operates in a narrow band (180 kHz) of the licensed radio spectrum and is designed for massive IoT deployments. However, it does not support voice communications.

Final Thoughts

As voice communication continues to grow in IoT, Eseye stands at the forefront, offering innovative and secure solutions tailored to global businesses. Whether leveraging VoIP for cloud-based interactions, VoLTE for high-quality voice, or VoWiFi for connectivity in challenging environments, Eseye ensures seamless and reliable communication for every IoT need.
