The introduction of new smartphones poses an ongoing challenge for network operators because they need to ensure ideal subscriber Quality of Experience (QoE) and avoid any disruption to their network performance. Usually, at the beginning of every new calendar year, the leading market players launch their most powerful end-user devices based on the newest chipsets, often synchronized with the main event in the telecommunication industry – the Mobile World Congress. The newly announced flagship devices like the Samsung Galaxy S22 or the latest Oppo model will be particularly challenging in terms of network testing. Their new chipset powered by Qualcomm Snapdragon® 8 Gen 1 Mobile Platform offers the most advanced 5G platform ever built by Qualcomm. The integrated Snapdragon® X65 5G Modem-RF System will usher into a new era and offer unprecedented data speeds of up to 10 Gbps. All these new features and technologies require a thorough test procedure before the commercial launch.
Rohde & Schwarz mobile network testing supports the Samsung Galaxy S22 and the pre-announced Oppo flagship model in its solution portfolio and enables mobile network operators and service providers to get a comprehensive view of the device and feature performance in their networks, already before the end-user devices are commercially launched.
Gregor Tomic, Product Manager says, “We are proud to meet our customers’ expectations, enabling them to successfully and timely implement their network engineering tasks before the official market introduction of new flagship devices. R&S®ROMES4, our universal mobile network testing software enables our customers to verify the performance of the latest Snapdragon® X65 5G Modem-RF System. And, there are many more technical aspects and parameters that have to be thoroughly tested and analyzed in the network engineering phase, to avoid potential end-user-centric issues or network degradation. In the R&S®ROMES4 print screen further below, we visualized a few key parameters, including:
- 3GPP overview, displays a 5G SA carrier aggregation connection established over 100MHz bandwidth
- Throughput with details on the physical downlink channel
- Layer 3 downlink and uplink decoding, offers valuable insights into the communication between the device and the network, which is a great tool for troubleshooting purposes
To get more information, meet us at Mobile World Congress 2022 in Barcelona or visit the R&S®ROMES4 product page."
