Carrier frequency offset (CFO) spec.

Hi,
I am trying an algorithm for CFO cancellation.
I would like to know how well the algorithm performs with respect to the CFO required for commercial systems.
Unfortunately, after googling a lot (web+scholar) I could not find any proper table/list/article that defines what is the allowed CFO in relevant applications.
I believe there should be such a specification. For example: suppose we have a QPSK receiver which we use to demodulate the input at a given frequency f. what is the possible deviation of commercial devices in the value of f ?
Are there any numbers about the CFO in popular standards ?
I could find only a vague saying that in IEEE 802.11, 40 ppm CFO is allows.. but what does it mean ? with respect to 2.4 GHz ?
Please help me to get more data here.
Thank you,
