This new WiFi6 is designed to work between 2.4G-5G Hz, and it is not just this frequency range. Once available, its spectrum range can even be extended to other frequencies between 1-7GHz. any frequency band.
This new standard improves the network speed of 2.4GHz, because it has excellent penetration in this frequency band. If you want the WiFi range to be wider without being hindered, it is correct to use WiFi in this frequency band. choose.
From the beginning of WiFi to today’s WiFi 6th generation. Its changes are visible to the naked eye. Nowadays wifi 6th generation means higher and faster, and it can accommodate more users.
