Chapter 13 AP Profile • 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. Table 56 WiFi 6 and WiFi 6E Comparison FEATURES WIFI 6 WIFI 6E Theoretical Maximum Speed (Up-to) The same (9.6 Gbps). Supported Frequency Bands 2.4 GHz/5 GHz 2.4 GHz/5 GHz/6 GHz Supported Channel Bandwidth 20/40/80/160 MHz 20/40/80/160 MHz Total Spectrum (Up-to) 2.4 GHz 80 MHz 5 GHz 500 MHz 6 GHz Not supported. 1200 MHz Other Features (OFDMA/BSS Coloring/TWT/Two-Way MU-MIMO/ Beamforming/1024-QAM) The same (WiFi 6E inherits all the features from WiFi 6).
