I am confused on whether 802.11a and 802.11g have the same data rates.

The following are from the CWNA OSG V3

PG. 186
- "802.11g devices can also use DSSS when communicating with 802.11b devices".
My understanding is that DSSS offers 1, 2, 5.5, and 11 Mbps.

PG. 212
- "802.11a-although it offers the same data rates as 802.11g,..."
States here that 802.11a and 802.11g offer same data rates.

Pg. 314
- States 802.11a data rates of 6, 9, 12, 18, 24, 36, 48, and 54 Mbps.

This website which shows specs on different Linksys hardware shows data rates being different for 802.11a and 802.11g.

Can someone please clear this up.

Thank you!

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.
