The Wi-Fi Alliance officially launched its Wi-Fi 6 certification program on Monday, informally launching widespread adoption of the new Wi-Fi standard. As with previous group certification programs, the Wi-Fi 6 certification program focuses on interoperability testing and feature sets on IEEE 802.11ax devices, ensuring that they work well with one another and that the devices have all the necessary requirements and the efficiency and security capabilities of the new standard.
Wi-Fi Alliance certification comes as device manufacturers have been delivering Wi-Fi 6 products for the past few months – essentially sowing the hardware ecosystem to get to that point. So the first task for group members and test labs will be to certify existing Wi-Fi 6 devices. This includes existing hotspots, routers and client devices, including Samsung's Galaxy Note 1
Under the hood, the new standard takes away a little from previous iterations of Wi-Fi, focusing more on improving performance in a shared environment, as opposed to merely increasing maximum device transfer rates. To this end, while the maximum bandwidth supported by Wi-Fi 6 is 2.4 Gbps, the crucial improvement in Wi-Fi 6 / 802.11ax technology is the improved spectral efficiency of the standard. Among other things, the technology adds OFDMA (Orthogonal Frequency-Division Multiple Access) to allow different devices to be served on a single channel by separating different sub-carriers for individual client devices. Wi-Fi 6 also adds mandatory support for MU-MIMO – a feature originally added to 802.11ac Wave 2 – as well as transmitting beam formatting to better reach individual customers.
In fact, even existing Wi-Fi 5 (802.11ac) client devices can benefit from Wi-Fi 6 (802.11ax) AP, although Wi-Fi 6 certified devices will perform best.
Meanwhile, the Wi-Fi Alliance has designated that Wi-Fi 6 certified devices support WPA3 security, 1024-QAM, 160 MHz channels, and these devices support target wake-up time (battery-saving technology that minimizes battery checks devices).
Finally, with the launch of the certification program itself, the Wi-Fi Alliance has already certified its top ten devices. The following network adapters, chipsets and hotspots are Wi-Fi 6 certified:
- Broadcom BCM4375
