Status of WIFI 6GHz frequency band allocation in the world

With the official opening of MWC2022, the world's most influential mobile communication exhibition, Qualcomm launched the world's first Wi-Fi 7 solution - FastConnect 7800, which supports a peak speed of up to 5.8Gbps and a latency of less than 2ms. The public also expects to transition from the mature WIFI4 and WIFI5 to the updated WIFI6, WIFI6E and WIFI7 products to enjoy a smoother wireless experience. The distribution of the 6GHz frequency band related to WIFI in various regions of the world is also the focus of wireless-oriented people.

The frequency band used by WIFI6 is the same as that of WIFI5, namely 2.4GHz+5GHz, but only supports the updated 802.11 AX protocol. WIFI6E and WIFI7 support 2.4GHz+5GHz+6GHz with tri-band at the same time. From the figure, we can see that the frequency range of 6GHz is 5.925~7.125GHz, with a total bandwidth of 1200MHz, which can accommodate 7 frequency bands of 160MHz, or 14 frequency bands of 80MHz and 60 frequency bands of 20MHz, which greatly expands the WIFI frequency band and reduces the frequency of daily WIFI. Frequency interference will decrease a lot.

At present, the division of WIFI 6GHz in various regions of the world has not been completely clear. The following is the classification status of each major region.

Country and Region Classification Status of 6GHz
The US,Canada,Latin America All for WIFI
EU, UK 5.925~6.425GHz for WIFI
Japan, Korea All for WIFI
Australia New Zealand undecided
China undecided
Brazil, Chile All for WIFI

It can be seen from the chart that overseas use of WIFI 6GHz is relatively clear, and my country has not yet determined it, so the current WIFI6E and WIFI7 cannot use the 6GHz frequency band in principle.

However, we can also experience better performance than WIFI4 and WIFI5 through the new protocols of WIFI6 and WIFI7. Similarly, chip manufacturers also allow users to experience better throughput performance through technical aspects. For example, Q2064PM1 designed with Qualcomm QCA206X series chips, although only supports 2.4GHz+5GHz, but through DBS (Dual-Band Simultaneous) concurrent dual-band technology, 2.4GHz+5GHz is combo, which further improves the transmission throughput.
