PCTEST Engineering Laboratory LLC, a recent addition to the Element Materials Technology Group, now offers 5G voice over new radio (VoNR) testing with the Rohde & Schwarz (R&S) CMX500 5G radio communication tester. The R&S CMX500 can simulate a 5G standalone network including IP multimedia subsystem services as well as exercise all critical VoNR functions.
VoNR is mandatory for the successful deployment of 5G standalone, the next stage of evolution for 5G

Emergency services require continued reliability of emergency (E911) voice calls and accurate determination of vertical and horizontal location in mobile devices, critical to U.S. Federal Communications Commission requirements. 5G VoNR will play an important role in this area, as E911 on 5G standalone networks utilize VoNR. The R&S CMX500 radio communication tester supports E911 over VoNR along with associated location determination technologies such as A-GNSS and AML/ELS.
"The R&S CMX500 is an extremely comprehensive, flexible and high performance VoNR test solution. As 5G pushes the limits of wireless, the R&S CMX500, which can already cover data rates of 6-10Gbps, will be ready for any new testing challenge that comes its way," said Bryan Helmick, product manager, Rohde & Schwarz.
