![]() This active scanning approach involves sending probe request frames along the 2.4 GHz and 5 GHz frequency spectrum. Client devices use an active “ hunt-and-seek ” approach to scan for existing APs. Traditionally, wireless devices communicate with access points in a specific exchange of information. The introduction of Wi-Fi 6E and the 6 GHz frequency band brings two new methods of communication between client devices and APs. So, in a space with more access points at lower power, devices on 6 GHz can operate over 59 20 MHz-wide channels.ĭownload the PDF version of our detailed 6GHz WiFi channel plan from here On low power mode, there are no restrictions, and APs can use the entire 1200 MHz spectrum range. With 1200 MHz of additional bandwidth, in the US 6 GHz allows for up to seven 160 MHz-wide channels, fourteen 80 MHz-wide channels, twenty-nine 40 MHz-wide channels and a whopping fifty-nine 20 MHz-wide channels.Īt a normal power mode, APs are only allowed to access 850 MHz of spectrum space. At 160 MHz-wide, 7 of these new channels are "superwide". With access to the 6 GHz spectrum, a whole new landscape of channel availability is among us. In April of 2020, the FCC unanimously voted to open the 6 GHz band for unlicensed use in the US.įollowing the change in FCC rules, the Wi-Fi Alliance added the Wi-Fi 6E designation in 2020 for devices that support the 6 GHz spectrum. ![]() Wi-Fi 6 was initially limited to the 2.4 GHz and 5 GHz wireless frequency bands due to Federal Communications Commission (FCC) regulation in the United States. The IEEE 802.11ax-2021 standard, which has been marketed by the Wi-Fi Alliance as Wi-Fi 6, focused on high-efficiency for overall improvements in dense environments.
