General Test cooperates with Anritsu to successfully implement Wi-Fi 7 320MHz broadband transmission OTA test
General Test announced that it has integrated Anritsu's wireless connection tester MT8862A into its OTA test system product. Each model of the RayZone? series OTA chamber combined with the MT8862A can support the latest 802.11be (Wi-Fi 7) 320MHz broadband transmission OTA test.

IEEE 802.11be (Wi-Fi 7), as the successor of IEEE 802.11ax (Wi-Fi 6/6E), aims to achieve high-speed communication that greatly exceeds the data throughput rate of IEEE 802.11ax. The standard is expected to become the foundational technology to support the latest applications and services such as ultra-high-resolution video streaming beyond 4K and AR/VR. Although the standard is scheduled to be officially released in 2024, product development based on the draft standard is in intensive progress, and leading companies have already begun to bring their products to the market. 802.11be uses innovative technologies such as 320 MHz bandwidth, 4096 QAM modulation, and Multiple RU, which requires a comprehensive evaluation of radio frequency performance. Ensuring that product OTA performance is qualified is an important task in Wi-Fi 7 product development, and it is also a great challenge.
For communication scenarios where Wi-Fi has a bandwidth exceeding 20MHz in actual use, General Test not only provides configuration templates that meet the CTIA Wi-Fi test specifications in the latest test software, but also provides various configuration templates that fully comply with the IEEE 802.11 protocol specifications. Configuration template for bandwidth (including 320MHz) communication scenarios. For channel scenarios with a bandwidth exceeding 20MHz, General Test has specially upgraded the "full bandwidth integral path compensation algorithm" this time, making the OTA measurement results in communication scenarios with a bandwidth exceeding 20MHz more accurate and more in line with the actual working conditions of the equipment.
Anritsu's MT8862A wireless connection tester is an integrated test solution that supports WLAN RF measurements of IEEE 802.11a/b/g/n/ac/ax/be as well as 2.4, 5, 6 GHz frequency bands and 320 MHz channel bandwidth. With its stable wide dynamic range communication capabilities, it is an ideal WLAN OTA measurement instrument solution. By integrating with the RayZone? series of full-model OTA test systems, it can stably and reliably test Wi-Fi 7 devices in the air interface environment. The total radiated power (TRP) and total isotropic sensitivity (TIS) OTA performance indicators. With the help of Universal Test's RayZone? full range of OTA test systems and Anritsu's MT8862A meter, users can achieve comprehensive measurements of the OTA performance of Wi-Fi 7 devices.
Anritsu MT8862A
This time, through the in-depth technical integration of both parties and the in-depth optimization of 802.11be testing, the General Test RayZone? full range of darkroom/test systems and the Anritsu MT8862A wireless connection tester are perfectly integrated, capable of comprehensively, quickly and accurately testing various types of Wi-Fi 7 devices OTA performance. The powerful combination of General Test and Anritsu can help customers deal with the RF and OTA testing challenges of Wi-Fi 7 on their own, and quickly bring products that support the latest WLAN technology to the market to take advantage of the opportunity.
General Test is an excellent wireless performance testing solution provider and an active participant and promoter of industry standards development. We are pleased to cooperate with Anritsu to support the performance evaluation and measurement of the latest Wi-Fi 7 devices. In the future, Universal Testing will continue to work with leading partners to jointly provide better testing solutions.
