• 5G, leveraging higher frequencies, marks a notable advancement from its predecessor, 4G. This transition offers 5G users a bandwidth that significantly eclipses that of earlier networks. While 5G networks do packetize voice traffic, they introduce a new term: New Radio (NR), serving as the 5G equivalent to LTE. The voice service under this new paradigm is termed Voice over NR (VoNR), or occasionally, Vo5G. Despite these advancements, most consumers are anticipated to continue using 4G for voice calls well into the next decade. Meanwhile, many carriers channel their 5G networks towards data-intensive tasks, such as streaming HD videos and music, relegating voice calls to older networks.
• Vo5G is poised to transform voice communications with ultra-HD capabilities. As 5G technology advances, voice is becoming central to services like telepresence, augmented and virtual reality, remote robotics, and a myriad of IoT applications in entertainment, gaming, industry, and healthcare. By integrating Vo5G, these services will not only elevate user experiences but also spur innovation across sectors, allowing businesses to tap into new opportunities and boost operational efficiency. Moreover, the promise of high-definition voice communication ensures that 5G services cater to the rising demand for seamless, reliable connectivity.
• The market for Vo5G is expected to face significant challenges that restrict its growth. The high infrastructure setup cost drives these challenges during its initial rollout phase, and several factors like network densification, expensive network upgrades, and less coverage across low-economy countries, and others.
