Open WiFi Success at OCP Summit 2018
Posted by Robin Jellum on Mar 23, 2018

I have been around the networking business long enough to remember the early days of the InterOp trade show, before it became N+I and the other variants. The two things I remember most about it was laying out a thick Ethernet cable the length of the show for the network backbone, and the excitement that we were part of changing the world.

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.
