Voice over New Radio (VoNR) and How it Compares with VoLTE, Based on Testing on T-Mobile's Network, 2023 Benchmark StudyDUBLIN, April 19, 2023 /PRNewswire/ -- The "Signals Ahead 5G NR Benchmark Study Vol 27: Behind the VoNR Curtain" report has been added to ResearchAndMarkets.com's offering.
Highlights of the Report include the following: This study was conducted in collaboration with Accuver Americas (XCAL-M and XCAP) and Spirent Communications (Umetrix Voice and Umetrix Data). The publisher is responsible for the data collection and all analysis and commentary provided in this report. Methodology Testing took place over a two-day period in early July. The publisher had access to a T-Mobile 17-site test cluster that is part of its commercial network. Using 2 Galaxy S21 with pre-release software that supported VoNR and SA the publisher did comparative drive and stationary testing with two Galaxy S20 smartphones that supported VoLTE. The publisher tested VoNR in both Band n71 (600 MHz) and Band n41 (2500 MHz), including with background data transfers taking place during the call. Four Areas of Focus The pulisher looked at voice quality (MOS), network resource utilization, background data transfers, and current consumption. The publisher did this comparative testing while stationary and/or via extensive drive testing throughout the cluster where the smartphones were exposed to a wide range of RF conditions. It's Nuanced VoLTE offered a huge advantage over circuit switched 3G voice in terms of superior voice quality, not to mention the elimination of CSFB (circuit switched fallback). VoNR and VoLTE both use the same EVS codec so the benefits of VoNR over VoLTE are less obvious. "Staying Alive" on 5G Without question, the biggest advantage of VoNR is that it allows the smartphone to remain on 5G, which proves beneficial when background data transfers occur. Longer term, moving all traffic to 5G SA helps with technology migration while SA offers certain performance benefits over NSA that are unrelated to voice. Balancing Act 5G networks are not as mature as LTE so RF conditions are not always as favorable. 5G current consumption is a consideration, especially when VoNR occurs in Band n41. Lastly, 5G network resource utilization can be better optimized for low bit rate voice calls.
