Voice over NR
Voice over New Radio or Voice over 5G (acronym VoNR or Vo5G) is a high-speed wireless
communication standard for voice services over 5G networks, utilizing mobile phones, data
terminals, IoT devices, and wearables.[1] Like 4G networks, 5G do not natively support voice calls
traditionally carried over circuit-switched technology.[2] Instead, voice communication is transmitted
over the IP network, similar to IPTV services. To address this, Voice over NR (VoNR) is implemented,
allowing voice calls to be carried over the 5G network using the same packet-switched
infrastructure as other IP-based services, such as video streaming and messaging.[3]
Similar to how VoLTE enables voice calls on 4G networks, VoNR (Vo5G) serves as the 5G equivalent
for voice communication, but it requires a 5G standalone (SA) network to function.[4] VoNR offers
better voice quality than its 4G predecessor, primarily due to the inherent lower latency of 5G NR,
allowing for faster call setup and improved overall communication.[5] Additionally, VoNR removes
the LTE anchor, enabling the voice call to stay entirely within the 5G network.[6]
VoNR (Vo5G) calls are generally charged at the same rate as other calls, and to make a VoNR call,
the device, its firmware, and the mobile telephone provider must all support the service and work
together in the specific area.
