Validating wi-fi 7 RF performance with the IQxel-MX series

Young Huang, Team lead of applications, explored the validation of Wi-Fi 7 technology in RF performance. He focused on the real-world performance and market acceptance of Wi-Fi 7 systems, where RF performance is a crucial aspect for direct competition. He pointed out key viewpoints such as UL-OFDMA technology, transmission range, and transmission rate, along with validating the actual benefits of Wi-Fi 7 coexisting with other wireless communication technologies. Since Wi-Fi 7 requires the use of the 6GHz spectrum band to achieve optimal benefits of 320MB bandwidth and 4096 QAM modulation, validation of test strategies under different transmit power settings is necessary due to frequency interference in the 6GHz spectrum band, involving AFC-defined functions and actual simulation of the test environment.

Furthermore, in system performance testing, involving range and rate testing validation, examining transmission latency, range, and rate verification is crucial. By using IQsniffer products as intermediate monitoring tools, besides analyzing the PHY and MAC layer performance of the RF transmitter, it also measures Wi-Fi and BT signal interference, analyzing results above the MAC layer. These are important challenges faced in the design of Wi-Fi 7 systems, echoing the importance of LitePoint’s testing machine capabilities. Responding to the new technical challenges of Wi-Fi 7, LitePoint deploys the IQxel series, led by the IQxel-MX series, with IQfact+ automated testing software to satisfy complete RF performance testing needs.

Unlocking the full potential of 5G: 5G advanced technology leading new applications

Senior Product Manager Middle Wen presented on the current trending topic of 5G Advanced technology. He began by noting that about half of the lifecycle of the 5G era has passed since its inception. The use of a true 5G Standalone (SA) standard network will dominate the future of subsequent 5G applications, marking the birth of the 5G-A era. The related functions and specifications will be defined by the 3GPP’s R17, R18, and R19 standards. Looking at the new features of 5G-A from the perspective of the 3GPP R17 standard, he listed several, including the Sidelink standard, which focuses on direct connections between devices, followed by the RedCap standard and the significant development of NTN technology for satellite communications. Other features include Network Slicing technology specifications, the introduction of AI/ML to enhance network connection efficiency, and further evolution of power-saving functions in 5G networks. The use of additional spectrum and the transition to the next-generation 6G network will be completed with the subsequent release of 3GPP standards.

Furthermore, regarding the highly regarded RedCap standard, the R17 version is tailored to the needs of wearable devices, industrial sensors, and security surveillance cameras. The R18 RedCap standard actively discusses replacing traditional IoT device connection methods. Additionally, NTN networks represent another groundbreaking change, defining IoT-NTN and NR-NTN architectures. Traditional satellites, which only performed direct signal transmission, have evolved into new-type satellites with base station functionality, completing the definition of regenerative satellites. In the future, mobile phones will be able to directly connect to satellites for data transmission. The 3GPP plans to standardize satellite communications and create examples of seamless mobile phone and satellite connections. Promising applications in the 5G-A era include AR/VR, industrial 5G private networks, IoT connections under RedCap, autonomous vehicle systems, and a wide range of smart applications composed of LBS technology.

Regarding LitePoint’s testing solution product strategy, it involves supporting the FR1, FR2, and FR3 spectrums, including the expansion and development of signaling and non-signaling machines. The product strategy for automated testing software will be customized and differentiated for chipset and module manufacturers. Other testing tools are convenient and practical, advocating a plug-and-play usage approach. As 5G-A technology undergoes significant modifications to welcome the SA network architecture, more changes to the 5G SA network will soon captivate consumers’ attention.
