New definition of mobile communication: R & scmx500 will improve the IP data throughput of 5g devices

  With 2022 year 3 month ,3GPP Third edition Release17 Functionality freeze , Officially declare the completion of 5G The first stage of evolution . There are more than 205 Operators deployed 5G Commercial network , future ,5G The application scenarios of will tend to be diversified , Expand to other than mobile phones VR、AR And new terminals such as metauniverse . among , Throughput is one of the important parameters to measure the experience of these scenes . Higher data throughput will drive 4K and 8K The wide application of HD video , And augmented reality 、 The ultimate realization of more immersive extreme user experience, such as virtual reality .R&SCMX500 The radio communication tester can well meet the maximum requirements that can be provided by testing the transmitter and receiver of mobile devices  IP throughput .

  Enhanced mobile broadband (eMBB) yes 5G One of the three pillars of new air port technology . Smartphone and other vertical market users are interested in 5G Higher requirements for network speed and capacity , Push 3GPP In more than 24 GHz Millimeter wave range （ namely FR2 Frequency band ） Defined 5G spectrum . However , While the performance is improved, it also puts forward higher requirements for the test level ： The new parameter set and available radio resources support larger bandwidth and a wider range of carrier aggregation scenarios , More complex downlink and uplink tests are required .

  however , To meet the actual use expectations of end users , Developers not only need to pay attention to the throughput of the RF layer , We must also pay attention to IP layer , Because it is important to ensure the quality of the end-user experience (QoE) It's crucial . It is critical to identify bottlenecks by performing multi-layer throughput tests , We need powerful testing and measuring equipment that can provide repeatable test results . Convenient monitoring and tuning tools help optimize business channels , It can be widely used in different layers and protocols （ for example TCP or UDP） Various applications of .

Rod and Schwartz solutions

 R&SCMX500 The radio communication tester has powerful hardware architecture and rich tools , Dedicated to speeds over 20 Gbps The data of , Can create unique LTE and 5G Test environment . The fully integrated software tool chain simplifies the RF layer and IP Throughput test of uplink and downlink of layer and application layer .

  Integrated MAC Throughput monitors help in FR1 and FR2 Frequency range analysis low-level throughput . Integrated Iperf Tools and powerful R&S Throughput 2 The application allows users to quickly check TCP and UDP Throughput value of traffic . Various throughput charts can visually display the values of each layer , In order to identify and isolate throughput bottlenecks and integration problems .

Throughput wizard simplifies test setup

 IP Throughput testing includes measurement and tuning . Integrated maximum throughput wizard combined with convenient graphical user interface , Greatly simplifies the test setup —— Users only need to input basic test setup data and unit configuration . The wizard will create a preconfigured test scenario based on the maximum data rate , And arrange R&SCMX500 work area . Users can start measuring directly , And monitor the measured data in real time through the multi-layer throughput graph . The measurement results can be used to analyze the potential bottlenecks caused by the interface capacity or configuration settings of each layer .

Automatically improve throughput performance

  Next , Users can use the unique IP Tuner and R&S Throughput 2 Application configuration network IP And stack parameters , In order to automatically improve throughput performance . This tool searches the highest  MCS value , To transmit the useful bits in the symbol . Important IP Channel parameters are also taken into account . The resulting value supports uplink and downlink throughput optimization , And it can be automatically applied to the scheduling configuration of user equipment for further measurement . Maximum throughput wizard and IP Tuning applications can be well applied to identify throughput problems .

Use R&SCMsequencer Realize test automation

  When the test scenario involves multiple frequency bands and carrier aggregation , Throughput testing will become more complex .R&SCMsequencer The advantage of is that it can automatically perform the maximum throughput test , And provide a wide range of end-to-end IP Layer test . The random permutation function can quickly and automatically perform iterative operations for the frequency band and frequency band combination reported by the equipment under test . When users test in all available combinations IP Throughput performance , This can significantly reduce time and workload .

Remote control

  Script plays an increasingly important role in production and development .R&SCMX500 have SCPI Interface and based on XLAPI Python The new interface . These two interfaces can connect R&SCMX500 Integrated into the software environment for remote control R&SCMX500 And most functions .

Abstract

  In the digital 、 Information age , Streaming media 、VR、 Application scenarios such as metauniverse constantly put forward higher requirements for the clarity and stability of video transmission . With the continuous expansion of the global user scale , be based on 5G The service application scenario of will face a more complex network environment , For related equipment 、 Optimization and improvement of infrastructure performance is imminent . All major equipment manufacturers and network operators hope to realize it more easily in a more cost-effective way IP Throughput testing and optimization . Provided by rod and Schwartz R&SCMX500 The platform can combine throughput wizards with IP Tune the application , Committed to providing users with all necessary tools , by 5G Equipment evaluates and optimizes throughput signal attributes .
