This trial showcased a fully native 5G voice experience with uninterrupted connectivity. Expanding on its innovative work in 5G technology, Dialog had previously conducted a lab-based VoNR proof of concept (PoC) in 2023 using a PoC Core setup.
This recent achievement on Dialog’s live 5G standalone (5G SA) core network demonstrates the practicality of VoNR services in real-world scenarios. VoNR offers clearer voice quality, faster call connections, and enhanced security compared to older 2G/3G or VoLTE services. It also paves the way for future features, such as 5G New Calling (5G NC), and boosts network efficiency by utilizing 5G spectrum more effectively.
Ranga Kariyawasam, Group Chief Technology Officer of Dialog Axiata PLC, stated, “This milestone highlights Dialog’s dedication to advancing Sri Lanka’s 5G technology. Successfully testing VoNR on our live 5G network brings us closer to fully utilizing next-generation connectivity, providing seamless, high-quality voice services over 5G.”
This achievement adds to Dialog’s list of 5G accomplishments, including the first 5G trial network in the region, the initial 5G SA network trial, Sri Lanka’s first standards-based 5G fixed-wireless pilot transmission, and its achievement of over 6 Gbps on its 5G-Advanced trial network. These milestones showcase the potential of next-generation 5.5G technology. Dialog remains committed to leading technological advancements, speeding up the adoption of next-generation connectivity, and bringing ‘The Future. Today.’ to Sri Lanka.
