You are correct in thinking the fact that it will provide some interference with the existing .11g network.

However, from what I gathered, the technology in AFHSS along with any other 802.15 WPAN, enables the device to work with the existing 802.11 network with little interference since AFH is effective in sending the data on frequencies that are not causing interference during that transmission. We are talking about 1600 hops per second on 79 different channels (US at least), and the ability to dynamically adjust those hops should the device detect interference.

Like having several Bluetooth v1.2 keyboards and mice on several laptops accessing the same AP. Interference will be minimal and most likely, depending and the amount of devices, will be un-noticable.

Thats how I view it at least. Please, by all means, some one correct me if I am wrong.

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.
