We are finalizing our design proposals for moving forward with 802.11n on campus, and I need some insight from other administrators that have world experience with 11n. As I see it, we can enable high-throughput without channel bonding and reap many benefits of 11n while maintaining a 9 channel plan (i.e., UNII-1 and UNII-3). An alternative is to enable channel bonding, which could increase throughput even more-so for 11n devices, but it will inevitably cause an increase in co-channel interference, thus resulting in more collision avoidance - not to mention that 11a devices receive no 11n benefits while still being confined to 4 20MHz channels.

So the question is, which have you seen result in better performance: channel bonding or more channels?

I appreciate any and all feedback!

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.
