• 1024-QAM (Quadrature Amplitude Modulation) – enhances the data capacity of each transmission
unit.
• 160 MHz Channel Bandwidth – extends the supported channel bandwidth to 160 MHz, providing
higher data throughput.
Enhanced Air Time Utilization
WiFi 6 increases transmission performance in high-density environments that have multiple client devices
with the following features:
• OFDMA (Orthogonal Frequency-Division Multiple Access) – divides channels into sub-channels that
enables multiple transmissions in a single channel.
• BSS Coloring – tags traffic by BSS (Basic Service Set) and identifies traffic from overlapping BSSs. The AP
can ignore traffic of unrelated BSSs and transmit data when a channel is occupied.
• MU-MIMO (Multiple User-Multiple Input Multiple Output) – enables multiple users to connect to the AP
and download/upload traffic simultaneously.
Extended Signal Range
Beamforming – forms the radiating signals into one direction. This enhances the signal strength and
extends the signal transmission range.
Extended Battery Life
TWT (Target Wake Time) – The AP negotiates with client devices so client devices only wakes up and
communicates with the AP in specific periods. This conserves client devices battery life.
WiFi 6E (IEEE 802.11ax - Extended Standard)
WiFi 6E is an extended standard of WiFi 6 (IEEE 802.11ax). WiFi 6E inherits all the WiFi 6 features and brings
with an additional 6 GHz band. The 6 GHz band allows you to avoid possible congested traffic in the
lower 2.4 GHz and 5 GHz bands. WiFi clients must support WiFi 6E to connect to an AP using the 6 GHz
band.
You must use WPA3 for security with WiFi 6E.
Note: Check your client device's product specification to see if your client device supports
the 6 GHz band (WiFi 6E). If not, you should still use the 2.4/5 GHz bands for connection.
Below is a comparison table that shows the main differences between WiFi 6 and WiFi 6E.
