Bandwidth Information needed

Anyone know where can I find the bandwidth information of wireless communication standard, like GSM, CDMA, 802.11a,b,g, Zigbee .... .
What is the center frequency and bandwidth of each standard? Thanks.

I think you can always do a google on 'band allocation'.

Take a look at this frequency allocation chart:

Here is a link to a wireless glossary that links to pages for each standard:
