A multi-probe test system provides a comprehensive evaluation of RF performance
A recent collaboration combines a multi-probe over-the-air test system with wireless connectivity that is set to provide a comprehensive evaluation of RF performance.
Wi-Fi 7 is a standard designed to achieve high throughput for use cases such as ultra-high-definition video streaming, multi-user AR/VR/XR, and immersive gaming and entertainment. It is already being integrated into high-end smartphones, AR/VR devices and routers. The technology is expected to see further adoption in the future.
Advanced technologies such as 320 MHz channels, 4K QAM, and MLO (Multi-Link Operation) are incorporated in Wi-Fi 7. For device vendors, ensuring and guaranteeing the RF performance of their products is a critical challenge. Therefore, the comprehensive evaluation of RF performance, including OTA measurements, is becoming increasingly important.
Semiconductor specialist Anritsu has launched a new evaluation solution combining Microwave Vision Group’s (MVG) multi-probe OTA (Over The Air) test systems with its own Wireless Connectivity Test Set MT8862A to support IEEE 802.11be (Wi-Fi 7) OTA measurements.
This solution leverages Anritsu’s MT8862A to generate and analyse Wi-Fi 7 signals within MVG’s multi-probe OTA test systems, enabling manufacturers to efficiently perform Wi-Fi 7 RF evaluations through fast and stable measurement. Using the MT8862A’s network mode, RF evaluation can be performed at all data rates of major WLAN standards, including Wi-Fi 7. The setup also allows for the measurement of key parameters such as Total Radiated Power (TRP) and Total Isotropic Sensitivity (TIS).
“Integrating the MT8862A with our OTA systems brings the stability and speed needed to evaluate Wi-Fi 7 performance at every stage of development,” said Sun Kim, product manager at MVG. “It ensures a streamlined workflow for engineers seeking to validate EHT (Extremely High Throughput) performance.”
Keita Masuhara, product manager, IoT Test Solutions., Anritsu, said: “We are pleased to be able to provide high-quality Wi-Fi 7 OTA measurement solutions through our collaboration with MVG. We will continue to collaborate with industry leaders like this to provide our customers with a more stable and efficient measurement environment.”
Seamlessly integrated within MVG’s WaveStudio platform, combining Anritsu’s instrumentation with MVG’s advanced test chambers, provides a reliable and high-performance testing framework for verifying Wi-Fi 7 device compliance, helping wireless device manufacturers optimise their product development and validation processes.
