Looking for more information on the new 802.11G standard

hi,

I am currently working on my senior project for my bachelors...and
needed some information about the new 802.11G standard...

I have already ran through the basic searches and collected most of
the research that i need for background information, security
concerns, and all that good stuff...but now I am specifically looking
for information about the detailed changes between the .B and .G
standard...

Does anyone have any sources that I can use that contain detailed
informations and specifications for .G and .B standards...

please help...thanks in advance
