Understanding What is VoLTE or Voice over LTE

IoT devices must be equipped with specific hardware components to support VoLTE. These include a VoLTE-compatible LTE modem, IMS support, QoS capabilities, efficient power management, optimized antennas, high-quality audio hardware, compliance with network requirements, and robust security features. For instance, the Qualcomm Snapdragon X60 is a Modem-RF system that supports VoLTE and VoNR for advanced voice call features.

VoLTE relies on IP-based communication, which can be vulnerable to interception if encryption and security protocols are not properly implemented. Potential security challenges include man-in-the-middle (MITM) attacks, signaling-based attacks like denial of service (DoS), eavesdropping, and spoofing. Ensuring robust security measures and encryption is essential to protect VoLTE communications.

VoLTE and Vo5G (VoNR) offer different benefits. VoNR (Voice over 5G) generally provides superior voice quality, lower latency, and a unified 5G network experience compared to VoLTE (Voice over LTE). However, VoLTE is more widely available at present as it utilizes existing 4G infrastructure. VoNR is becoming more prevalent as 5G Standalone (5G SA) networks expand.
