Wi-Fi 7 performance testing and verification

31 May 2023 News

Anritsu Corporation and MediaTek Incorporated have successfully verified the performance and functions of MediaTek’s Filogic chip for IEEE802.11be WLAN, by testing RF characteristics with the network mode.

The IEEE802.11be (Wi-Fi 7) wireless communication standard being developed by the Institute of Electrical and Electronics Engineers is the successor to the IEEE802.11ax (Wi-Fi 6/6E) WLAN standard. The new standard is proposed to achieve a transmission speed of 30 Gbps or more, which is much faster than Wi-Fi 6/6E. In addition to extending conventional technologies, including 4096 QAM, 320 MHz channel bandwidth, and Multi-RU, it also adopts new technologies such as Multi-Link Operation (MLO), enabling a device to simultaneously send and receive data across different frequency bands and channels.

Development of IEEE802.11be is expected to be completed in 2024, and devices using chips based on the draft standard are already appearing to support the latest applications and services, such as ultra-high-definition video streaming and AR/VR.

The network mode emulates real operation to evaluate RF characteristics. It uses the data link layer communication protocol implemented in both the chip and tester to establish communication.

In addition to evaluating RF characteristics using conducted tests, the network mode is especially useful for OTA wireless performance tests including antenna characteristics of finished products.

MediaTek has released its Filogic 880 and Filogic 380 with world-leading high performance, low power, and high reliability for Wi-Fi 7 platforms. Due to the seamless, stable, high connectivity of MediaTek’s chips, their RF characteristics were evaluated jointly under actual operating conditions by using Anritsu’s network mode technology to establish and maintain the wireless communications. This evaluation of IEEE 802.11be RF characteristics with the network mode marks a world-first in wireless testing.
