Anritsu and Bluetest supporting OTA measurements on IEEE 802.11be (Wi-Fi 7) devices

Anritsu and Bluetest combine their recent product upgrades to create an Over-the-Air (OTA) measurement1 solution for verifying RF performance in tri-frequency bands of the latest WLAN standard.

This collaboration provides customers with a WLAN test solution capable of transmit power (TRP) and receive sensitivity (TIS) measurements on IEEE 802.11be supported devices. Measuring the OTA performance in life-like, but repeatable conditions, enables manufacturers of high-speed data transmission devices, including high-end smartphones, AR/VR devices and cloud gaming consoles, to optimize the radio performance and end-user satisfaction.

IEEE 802.11be is being standardized as the successor to IEEE 802.11ax (Wi-Fi 6/6E) and is targeted to realize high-speed communications that significantly exceed IEEE 802.11ax. The standard is expected to be a fundamental technology supporting the latest applications and services, such as ultra-high resolution video streaming beyond 4K and AR/VR.

Although the official release of the standard is scheduled for 2024, product development based on the draft standard is underway, and leading companies have already begun to bring their products to market. IEEE 802.11be adopts innovative technologies such as 320 MHz bandwidth, 4096 QAM modulation and Multiple RU, and a comprehensive evaluation of RF performance is required.

The Anritsu Wireless Connectivity Test Set MT8862A is dedicated to the WLAN standard, hence optimized for stable and reliable connections with wider dynamic range, even in a faded environment such as in the Bluetest reverberation chamber. It is now updated with a new radio module adding support for 320 MHz bandwidth, in addition to the supported 2.4, 5 and 6 GHz bands. The test setup is easily expanded to support 2x2 MIMO measurements using two MT8862A units.

The Anritsu MT8862A and all Bluetest chambers are available for order, and upgrade packages are offered for already installed systems.

Technical Terms
1 Over-The-Air (OTA) measurement
Measurement for accurately evaluating wireless device reliability, efficiency, and performance by sending/receiving over-the-air radio waves. This is especially useful for comprehensively evaluating the wireless communications performance of equipment including antennas.

2 Multi-link Operation
Technology enabling one device to simultaneously send and receive data across different frequency bands and channels.
