High-Efficiency (HE) APs
With the implementation of theIEEEInstitute of Electrical and Electronics Engineers.802.11ax standard, you can configure and improve spectrum efficiency and area throughput in dense deployment scenarios of APs or stations in both indoor and outdoor environments. You can configure High-Efficiency (HE) to operate on both the 2.4GHzGigahertz.and 5GHzGigahertz.frequencybandsBand refers to a specified range of frequencies of electromagnetic radiation.. HE is enabled by default, and can be enabled or disabled in the802.11a802.11a provides specifications for wireless systems. Networks using 802.11a operate at radio frequencies in the 5 GHz band. The specification uses a modulation scheme known as orthogonal frequency-division multiplexing (OFDM) that is especially well suited to use in office settings. The maximum data transfer rate is 54 Mbps.,802.11b802.11b is a WLAN standard often called Wi-Fi and is backward compatible with 802.11. Instead of the Phase-Shift Keying (PSK) modulation method used in 802.11 standards, 802.11b uses Complementary Code Keying (CCK) that allows higher data speeds and makes it less susceptible to multipath-propagation interference. 802.11b operates in the 2.4 GHz band and the maximum data transfer rate is 11 Mbps.,802.11g802.11g offers transmission over relatively short distances at up to 54 Mbps, compared with the 11 Mbps theoretical maximum of 802.11b standard. 802.11g employs Orthogonal Frequency Division Multiplexing (OFDM), the modulation scheme used in 802.11a, to obtain higher data speed. Computers or terminals set up for 802.11g can fall back to speed of 11 Mbps, so that 802.11b and 802.11g devices can be compatible within a single network.,802.11n802.11n is a wireless networking standard to improve network throughput over the two previous standards, 802.11a and 802.11g. With 802.11n, there will be a significant increase in the maximum raw data rate from 54 Mbps to 600 Mbps with the use of four spatial streams at a channel width of 40 MHz., and802.11ac802.11ac is a wireless networking standard in the 802.11 family that provides high-throughput WLANs on the 5 GHz band.radio profiles.

Wi-Fi can apply to products that use any 802.11 standard.Alliance's Agile Multiband Operation (MBO) certification. This certification enablesWi-FiWi-Fi is a technology that allows electronic devices to connect to a WLAN network, mainly using the 2.4 GHz and 5 GHz radio bands. Wi-Fi can apply to products that use any 802.11 standard.devices to better adapt to changing network conditions. It helps in improving resource utilization, balanced network load, and various other features.
The MBO certification also includes Cellular Data Capability (CDC). This provides APs or multi-mode capable STAs to advertise CDC support.
Theprofile configures the High-EfficiencySSIDService Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network.settings for 802.11ax. Use theprofile to configure your APs to allocate the whole channel to a single user at a time or partition a channel to serve multiple users simultaneously.

Configuring Advanced High-Efficiency SSID settings
Most deployments do not require manual configuration of the High-EfficiencySSIDService Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network.profile. However, you can configure advanced High-EfficiencySSIDService Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network.profile settings or modify defaultSSIDService Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network.profile values using the WebUI orCLICommand-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions..
In the WebUI
Perform the following task to configure advanced high efficiencySSIDService Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network.settings:
1.In thenode hierarchy, navigate to thetab.
2.Expand theaccordion.
3.Select.
4.Select the High-EfficiencySSIDService Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network.profile you want to edit or clickand enter a name into thedialog box to create a new profile.
5.Configure the High-EfficiencySSIDService Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network.profile settings described inTable 1.
