Hi Criss,

Thanks for your valuable information.

I have few questions over Barker preamble bit in 11g.
According to standard it is clearly mentioned that it will be set whenever a non-ERP station incapable of short preamble joins or.. when the AP/BSS is configured to allow only long preamble (i.e ShortpreambleImplemented is false)

But in devices such as Cisco the second condition is not realised.i.e When the Ap/BSS is configured for long only, the barker preamble bit is not set.
Only when a station either non-ERP/ERP connects to BSS the bit is set.

Can you please explain this inconsistency or anamoly?

With regards,
Murali

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.
