The course was excellent. The material covered was put together well, everything seem to flow together. Experience on wifi? I think it's like most course, the more the better but this course starts out with antenna make up and signal generation and works it's way threw the rest. This course also covers bluetooth, lots on encryption and how to beat it. Basically I think as long as you have some experience with the normal wireshark, tcpdump, etc you should do well. The equipment they give to you worked well together. Since my work payed for this it was nice to get the free stuff.
