Description of Feature Highlights

This Cisco 9115 AX AP has WiFi 6

WiFi 6 or 802.11ax is a “High Efficiency” standard intended to improve the efficiency of WiFi and make it more reliable and stable for WiFi communications. Our in-depth article on the top exciting WiFi 6 features can be referred for further understanding of 802.11ax WiFi 6 technology. Cisco 9115 AX is Wi-Fi CERTIFIED 6™ and can also extend support to client stations using previous legacy standards.


This Cisco WiFi 6 Access Point AP 9115 AX features Uplink/Downlink Orthogonal Frequency Division Multiple Access (OFDMA), a technology borrowed from the mobile phone industry. OFDMA vastly improves upon the existing OFDM technology used in WiFi APs. It allows multiple clients to share WiFi channels. This feature can relieve congestion in crowded offices as 802.11 ax stations need not wait to get access to a full channel and instead share the channel with others and get things done.

OFDMA can make the whole WLAN efficient as clients devices with smaller loads that form the bulk of wireless communications can quickly transmit data. Though this feature can only be fully utilized in an environment having only 802.11ax clients, legacy clients can also experience an upside as the air will clear out quickly due to efficient communications happening in 802.11ax ecosystem.


Downlink MU-MIMO (4 streams per radio, total 8 streams) helps the AP to communicate with multiple clients simultaneously. This helps the stations to get quick access to the Access Point, thereby increasing the number of clients that can be served by an AP. This feature generally improves airtime efficiency and speed for all the clients.

1024 QAM

This Cisco WiFi 6 AP can support 1024 QAM, which means faster data communications than currently possible. But to achieve such speeds, noise free environments will be needed along with closer ranges between access points and clients. Such requirements make it practically impossible to achieve the stated speeds in crowded environments that need constant WiFi signal management.

BSS Coloring

This Cisco 9115 AX AP supports BSS Coloring feature of the WiFi 6 standard. BSS Coloring feature has been carried forward from the 802.11ah “Wi-Fi HaLow” standard and it identifies each access point in a WLAN with a unique identifier called ‘color’. This helps client stations to safely ignore communications in neighboring access points with a different color and below a threshold power level, and keep transmitting. This speeds up communications as clients need not stop data transfers to access points due to transmissions happening else where in the WLAN network in the same channel. This greatly helps to overcome limitations posed on wireless communications by existing co-channel interference safe guards.

Target Wake Time

Target Wake Time is another feature inspired from the 802.11ah IoT standard. This feature helps the access point to wake up clients based on a pre-negotiated time interval to receive data. The clients can sleep during other times, helping them to save battery. This feature can greatly help customers choosing this access point for IoT applications.

Apple iOS Fast Lane

This feature, developed from the partnership between Cisco and Apple, helps iOS 10+ applications get priority in WiFi communications. This provides better service levels to end users having Apple iOS products. This can help organizations using Cisco 9115 AX AP to provide better WiFi connectivity to customers using Apple devices and delight them.

Embedded Wireless Controller (EWC)

Cisco 9115 AX access points contains Embedded Wireless Controller (EWC). Cisco has embedded Cisco 9800 controller software to simplify management of access points while retaining highest levels of security, performance and controls. Cisco claims that EWC embedded APs can help “simplify complexity, optimize IT, and reduce operational costs by leveraging intelligence, automation, and human expertise that no other vendor can deliver”. Upto 100 access points and upto 2000 clients can be managed with EWC, where primary and backup controllers can also be configured for resiliency purpose. EWC can work together with Cisco DNA to offer additional features for customers. Cisco DNA license will be a required purchase for multi-site management using EWC.

Cisco 9115 AX supports Cisco DNA

Cisco 9115 AX access points support Cisco Digital Network Architecture (DNA). Cisco DNA automates manual tasks and provides a centralized view of the network for enhanced management and security. “Cisco DNA automation capabilities transform previously manual on-boarding, configuration, provisioning, and software management processes”. Cisco DNA capable access points like 9115 AX can be on-boarded, managed, monitored and its various tasks automated through a centralized dashboard. The Cisco DNA service is currently available in 3 subscription tiers: Cisco DNA Essentials, Cisco DNA Advantage, and Cisco DNA Premier.

IoT Capabilities

This Cisco AP has a dedicated on-board radio to support BLE 5.0 stations for IoT . This eliminates the need to deploy additional infrastructure for certain IoT services. It can be useful in environments where IoT needs to be implemented in a cost effective way. The AP also provides container support for IoT applications.

WPA3 security and OEAP

WPA3 is the latest security standard approved by WiFi Alliance for keeping WiFi communications secure. WPA3 tackles the shortcomings of its predecessor WPA2 in encrypting data transfers and has been in use since 2018. WPA3 was a major update to WiFi security after 14 years since WPA2 was launched in 2004.

Also this AP can be operated in OEAP mode (Office Extend Access Point) for remote workers and branch offices to securely connect with Corporate network. This should be especially useful in the current COVID 19 pandemic situation. OEAP can help remote users and small branch offices setting up the AP to get access to Corporate SSIDs and their Corporate network without any need of deep technical expertise.
