Vodacom Makes Groundbreaking Stride: South Africa's Inaugural Native 5G Voice Call Using VoNR Technology Successfully Executed
Vodacom Pioneers Voice over New Radio (VoNR) Technology in South Africa
Vodacom, a leading telecommunications company in South Africa, has made a significant stride in the mobile communication industry by successfully testing Voice over New Radio (VoNR) technology on a test network. This achievement marks a significant milestone in South Africa's mobile communication evolution [1].
VoNR improves 5G voice call quality and network efficiency by enabling native voice calls entirely over 5G standalone (SA) networks. This results in faster call setup times, ultra-high-definition audio quality, and better battery efficiency on 5G-enabled devices [2][3].
The success of Vodacom's VoNR test could prompt other African operators to accelerate their own 5G voice initiatives. Consumers stand to benefit from VoNR with clearer conversations even in noisy environments, shorter call connection delays, longer battery life on 5G handsets, and an enhanced user experience with simultaneous high-speed data and voice over 5G [1][3][5].
Many recent smartphones, including the latest models from Apple and Samsung, already support VoNR, ensuring widespread compatibility and faster adoption [1]. Although a specific timeline for the commercial rollout of VoNR has not been disclosed, Vodacom remains optimistic about its future prospects.
Vodacom's investment in 5G has cemented its leadership in the African telecommunications sector. The company launched the first live 5G network in Johannesburg, Pretoria, and Cape Town in 2020 [6]. The expansion of Vodacom's 5G coverage is supported by temporary spectrum allocations from ICASA.
VoNR takes advantage of 5G's high-speed, low-latency capabilities, resulting in faster call setup times, better voice quality, and reduced background noise. The technology uses the 5G radio access network (gNB), the 5G core network (5GC), and the IP Multimedia Subsystem (IMS) with tighter integration than Voice over LTE (VoLTE). This integration supports improved quality of service (QoS) and seamless voice over 5G end-to-end [2].
The adoption of VoNR builds on the foundation established by Voice over LTE (VoLTE), which has been used in South Africa for over a decade. Vodacom's track record of early adoption, such as the 2015 launch of VoLTE in South Africa and the 2020 rollout of 5G, demonstrates the company's commitment to rapid innovation and deployment.
As 5G adoption continues to spread across the continent, the enhanced call quality and network efficiency provided by VoNR could reshape consumer expectations. Vodacom employed a "single packet core," a sophisticated setup that required cloud orchestration and network upgrades to seamlessly integrate voice and data services across multiple access technologies. With VoNR, Vodacom can accommodate more simultaneous calls, alleviating network congestion as data traffic continues to surge.
In summary, VoNR leverages full 5G capabilities to provide superior voice call quality and network efficiency, directly benefitting users through better call experiences and improved device battery performance while helping operators manage network resources more effectively as 5G data demand grows.
