WiFi6 / IEEE 802.11ax
WiFi 6 (802.11ax) is a WiFi standard that supports 2.4 GHz, 5 GHz and 6GHz frequency bands and brings
the following major improvements:
High Data Transmission Speed
WiFi 6 provides faster transmission data rate than its previous WiFi standards with the following features:
• 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 Server 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
Target Wake Time (TWT) allows the AP to negotiate with client devices so client devices only wakes up
and communicates with the AP in specific periods. This conserve 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.
