802.11b to 802.11g to 802.11n

By marko_bundalo ·
I am doing a research on these three WiFi standards. I am looking for professional in depth explaination of the differences between b and g, a nd g and n. Also, the reason why IEEE had to develop new standard because of the previous one.

by w2ktechman In reply to 802.11b to 802.11g to 802 ...

or surf the web

802.11b is on the 2.4Ghz band, and has a max speed of 11 Mbps
802.11A is on the 5 Ghz band and has a speed up to 54Mbps
802.11g is on the 2.4 Ghz band and has a speed up to 54Mbps
802.11n is on the 2.4 Ghz bandwidth, but may be also on the 5 Ghz bandwidth, I havent followed it closely enough to really specify much about it.

IEEE develops standards based on needs/new technology. Also, with these guidelines you can use multiple vendors equipment and they can still communicate.

Good question

Great question. As mentioned it would be quite difficult to list all of the differences. This link is to a free web seminar that touches on most of your inquiries. That might be best and then if you have more specific questions I am sure the members would be more than willing to help answer.
