In 2.4 GHz, the noise can be all over the place. -88 noise is Ok I guess in an outdoor deployment, but with highly directional antennas, noise is minimized compared to flat panel or patch antennas.

If the noise stays at -88 dBm it isn't the issue, but if the noise and signal fluctuate for the worse (lower SNR) then of course issues arise.

I can't stress it enough; 2.4 GHz is a poor choice for anything Wi-Fi that isn't used for backwards compatibility. 5 GHz is fairly clean, for now.

To answer the question more directly, noise doesn't matter, signal doesn't matter (bold statement I know). What matters is signal to noise. That is one major key to good communication.

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.
-Darren

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.
