Highlight Features Description

Extreme wireless WiFi 6 capabilities

WiFi 6 or 802.11ax is a “High Efficiency” standard as its core purpose is to improve the efficiency of WiFi communications and making it more stable and dependable under increasing user base and applications globally. We had earlier posted an in-depth article on the notable features of WiFi 6 access points that can transform WLANs. Extreme Networks 305 C/CX access points feature 802.11ax (WiFi 6) standard with support for client stations using previous legacy standards as well.

OFDMA (WiFi 6)

This Extreme Wireless WiFi 6 AP features Orthogonal Frequency Division Multiple Access (OFDMA), a technology that has been borrowed from the cell phone industry. OFDMA vastly improves upon the existing OFDM technology of WiFi access points. It allows multiple clients to have simultaneous access to a single WiFi channel. This feature will greatly help to relieve congestion in crowded offices as 802.11 ax stations need not compete with each other to get access to the whole channel and instead share the channel.

OFDMA makes the entire WLAN efficient as clients with smaller loads that usually form the bulk of communications need not occupy the full channel. They can instead co-transmit along with larger loads from other clients. Though this feature can only be fully utilized through 802.11ax clients, legacy clients will also experience the upside as the air will clear quickly due to efficient communications happening in 802.11ax.


Downlink MU-MIMO (2 streams per radio, total 4 streams) helps the AP to communicate with multiple clients simultaneously. This helps the client stations to get faster access to the AP and thereby increase the number of stations that can be served under an AP. This feature improves airtime efficiency and increases speeds for all the clients.

1024 QAM (WiFi 6)

This Extreme wireless WiFi 6 access point can support 1024 QAM, which means data transmissions at higher speeds than earlier standards are possible. But of course, achieving such higher speeds will need radio noise free environments and closer ranges between access points and stations. This requirement makes it practically impossible to achieve the rated speeds in dense enterprise environments requiring constant WiFi interference management.

Extreme Wireless WiFi 6 AP with Dual 5 GHz

It is possible to set the access point to have dual 5 Ghz radios, instead of dual bands of 2.4 GHz and 5 GHz. This helps to meet certain specific office requirements where there is need to support only a high density of 5 GHz clients and 2.4 GHz radio can be safely turned off.

Extreme wireless WiFi 6 AP with L2-L7 Firewall

The access point features the latest authentication technology of WPA3 that uses 192 bit encryption and Simultaneous Authentication of Equals (SAE) technology for enhanced security. The AP also has an inbuilt DPI firewall to handle layer 2 to layer 7 security at the edge.

IoT Capabilities

The AP has an on board radio to support BLE 5.0. This eliminates the need to deploy separate infrastructure for IoT services. It can be useful for certain retail environments trying to engage customers through bluetooth based notifications etc.
