To both of the last posts:

A Wi-Fi device's first priority is to decide if an incoming frame is in tact or not. It has to do that by reading the entire frame, calculate the CRC, and then check then compare that to the incoming frame's CRC. At that time, the device then has to read the entire MAC header. This is for one of two reasons. First, to see if the frame is destined for it (receiver address) and then to process any duration value.

If I am understanding the situation properly, the answer to the question is that every frame is read and processed (see above) by every device that can hear that transmission (Same channel, compatible modulation, etc).

Success Stories

I literally just came out of the testing centre having taken the CWDP exam. The certification process opened my mind to different techniques and solutions. This knowledge can only broaden your perspective. Great job, CWNP, you have a great thing going on here.

Working through the CWNP coursework and certifications helped not only to deepen my technical knowledge and understanding, but also it boosted my confidence. The hard work it took to earn my CWNE has been rewarding in so many ways.

I want to commend you and all at CWNP for having a great organization. You really 'raise the bar' on knowing Wi-Fi well. I have learned a ton of information that is helping my job experience and personal career goals, because of my CWAP/CWDP/CWSP studies. Kudos to all at CWNP.
