The CMP180 validates Wi-Fi 8 features including 5x5 MIMO.
Qualcomm Technologies has used the CMP180 radio communication tester from Rohde & Schwarz to validate advanced multi-antenna capabilities that are designed into its next-generation Wi-Fi 8 platforms, including support for 5x5 MIMO in the 2.4, 5 and 6 GHz band. Advanced 5x5 MIMO architectures help Wi‑Fi 8 platforms deliver higher capacity and more reliable connectivity across a wider range of real‑world deployment scenarios.
The industry leading CMP180 delivers full bandwidth and seamless scalability for testing leading Wi Fi 8 chipsets across the entire device lifecycle — from development to production. As a result of this collaboration, Rohde & Schwarz now offers pre built test routines and early access to key resources, enabling device manufacturers to accelerate time to market of their products.
Wi-Fi 8, based on the IEEE 802.11bn specification, builds on the foundation of Wi-Fi 7 to deliver next-level reliability, efficiency and seamless mobility. New PHY and MAC layer technologies work together to extend range, improve spectrum utilization, reduce latency and enable coordinated access across dense environments, setting the stage for ultra-high reliability (UHR) performance. Advanced antenna architectures such as 5x5 MIMO help enhance spatial efficiency and link robustness and provide a more consistent performance in real-world environments.
This new feature set of Wi-Fi 8 will accelerate the wireless LAN performance at home, in offices, venues and factories and enable applications like extended reality (XR), AI-assisted applications, real-time cloud gaming and ultra-high-definition content streaming. To realize these benefits, test equipment must support all bands, full channel bandwidths, multi-antenna operation (MIMO) and deliver best-in-class measurement accuracy at benchmarking test efficiency. Rohde & Schwarz has designed the CMP180 radio communication tester with these capabilities in mind.
The CMP180 enables Qualcomm Technologies to validate essential features of its latest Wi-Fi innovation, including:
• 5x5 MIMO performance to further improve maximum data throughput per link
• Advanced modulation and coding schemes that enable fine grained adaptation to real time radio conditions.
• Distributed-tone resource units to improve uplink performance under regulatory limits.
Goce Talaganov, Vice President Mobile Radio Testers at Rohde & Schwarz, said: “We are excited to strengthen our long-time collaboration with Qualcomm Technologies to provide a unique testing solution for the next area of Wi-Fi innovations. The CMP180’s advanced features and our close collaboration will empower device manufacturers to bring innovative Wi-Fi 8 products to market quickly and confidently.”
Ganesh Swaminathan, Vice President and General Manager, Wireless Infrastructure and Networking, Qualcomm Technologies, Inc. said: “Qualcomm Technologies’ Wi-Fi 8 portfolio is engineered to deliver next level performance, reliability and scalability across a broad range of networking use cases. As part of this portfolio approach, we are advancing innovations such as higher order MIMO to help increase performance in real world environments. Our collaboration with Rohde & Schwarz highlights the progress of these capabilities as the Wi-Fi 8 ecosystem builds momentum.”
