I am back on the books to do the final studying for the exam.
I am trying to understand the example in figure 2.18 of the 4th ed. CWNA book (page 80).
Why is the receive sensitivity on one side of the link not modified by the cable+antenna on that side?
It seems the calculations take into account the cable and antenna on one side of the link to come up with the -59 as the signal, but on the other side only the RS of -94 is used.
Shouldn't the fact that I have cable loss and antenna gain on the other side make a difference? If the bridge on the other side had an even more powerful antenna, would the SOM still be 35 dbm? How would the SOM equation take into account different antennas and cables on the two sides?
thanks!

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.
