What were once revolutionary words when talking about enterprise WLAN – monitoring, visibility, single-pane-of-glass management – now sound conventional to the ears of network managers. Today, for many, the features those words describe have evolved into what is now known as the “cloud console.”

As WiFi networks have moved from merely supporting the business to serving as its backbone, WLAN management must evolve as well. Yesterday's security, scalability, and remediation are inadequate for the digitally transformed enterprise in which WiFi is the conduit to customers, suppliers, and mission-critical business applications.

802.11ax: Optimistic CSMA for Efficient Channel Reuse in WiFi
Posted by Hemant Chaskar on Jul 9, 2016

802.11ax is the new 802.11 standard currently in the making. Unlike earlier 802.11 standards that mainly focused on increasing raw link speeds, the design objective now is to increase airtime efficiency. One feature it introduces is OFDMA (Orthogonal Frequency-Division Multiple Access) to address the airtime inefficiency caused by short WiFi frames. The other is dynamic sensitivity control, which modifies traditional CSMA (Carrier Sense Multiple Access) to address airtime inefficiency caused by co-channel interference during channel reuse.
