In recent years, with the rapid advancement of technology, WiFi technology has been continuously evolving, transitioning from WiFi 6 to WiFi 6E, and now garnering significant attention is WiFi 7. This time, our focus is on the latest WiFi 7 module developed by QOGRISYS: O7851PM. We will delve into the core metrics of WiFi 7, specifically throughput testing, to explore its performance advantages.
The foundational specifications of O7851PM: O7851PM is a WiFi 7 module designed based on the Qualcomm WCN7851 chip. It utilizes an M.2 PCIe interface with dimensions of 22*30*2.7mm. The module supports features such as 4096QAM, 320MHz bandwidth, Multi-RU mechanism, Multi-LINK multi-link mechanism, and incorporates WiFi 7 technologies including CMU-MIMO and collaborative debugging among multiple access points.
O7851PM Test Environment Setup:
1.Shielded Room
2.Testing Method:
The O7851PM module is used as an Access Point (AP), with another O7851PM module serving as a Station (STA) connected to the first O7851PM. Two external rod antennas, with two transmitters and two receivers, are connected via PCIe to a PC running a Linux system. The system is powered by a direct current power supply. The PC utilizes iperf to conduct throughput testing on the O7851PM module's TX/RX performance.
Actual Test Screenshots:

2、TCP DL/UL:6G EHT320(5764.8Mbps)
3、TCP DL/UL:5G EHT 160 (2402Mbps)
4、TCP DL/UL:5G HE160 (2402Mbps)
5、TCP DL/UL:6G HE160 (2402Mbps)
6、HBS: TCP DL/UL:5G EHT80 +6G EHT160 (1200Mbps+2402Mbps)
7、HBS: TCP DL/UL:5G EHT80 +5G EHT160 (1200Mbps+2402Mbps)
8、DBS: TCP DL/UL:2.4G EHT40 +5G EHT160 (600Mbps+2230Mbps)
The data summarized above：
From the above table, we can observe that the O7851PM WiFi 7 module not only supports the 6GHz frequency band but also introduces HBS. It also retains the WiFi 6E DBS functionality. In the real-world throughput test at 6GHz with a 320MHz bandwidth, the measured throughput can reach 3900Mbps. In summary, through the throughput testing of the O7851PM WiFi 7 module, we catch a glimpse of its outstanding performance in the field of wireless communication. Meanwhile, as experts in the wireless communication domain, QOGRISYS will continue to delve deep into wireless communication, providing users with more advanced and intelligent communication solutions to contribute to building a more interconnected future
