Go to Post I was dragged to the first team meeting in September my freshman year and a week later, found myself at Fall Classic. Needless to say, after experiencing the heat of a competition, I was in love. ... Robotics has become far more than just that. I get to do the coolest thing in the world. - Audrey Chu [more]

I know the report is long, but I urge everyone who wants to make a statement about the report read the entire report first. There have already been multiple posts in this thread containing false assumptions.

The next tests involved targeting the attack at the specific client (the robot radio) and throttling the rate at which the tool sent the de-authentication packets. These attacks were also successful at disrupting the communication, but were able to elude detection by the AirTight sensor. Further investigation into the thresholds for classifying an event of this type in the AirTight system revealed a minimum of 8 directed or 4 broadcast de-authentication packets per second for a minimum of 90 seconds must be detected for the AirTight system to flag and classify a denial of service event. FIRST has determined that these thresholds provide insufficient protection for the FRC wireless use case.
