Meet Steve, CIO of IT at a large University.  Like you, his number one priority is to deliver a stable wireless network for students and staff.  Not easy to do. Steve and his team of IT professionals struggle to keep up with ever increasing demands on the network; number of students connected, devices per student, security threats, high-density zones, and skyrocketing bandwidth as mobile is now at the center of learning and leisure.

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.
