Peter,
If you ever find a single source of data, it would be great. I currently live and breathe these requirements and have not found a single location for the data. The closest document that appears to be in existence is a summary from a chip vendor but it is now a year and a half old. (Before you ask, that document is under NDA so I can’t send it to you.) The WiFi alliance was also considering funding the creation and maintenance of such a list but that apparently never came to fruition. The regulatory information is also a moving target as you probably know. Every month or so something seems to change. The best that I can recommend is to work with a lab that does radio testing for a living. They usually have a lot of the data, particularly for the big economies, but not for all the smaller ones. A few words of warning – in addition to the parameters that you are looking for, you will need to know the DFS/TPC and Indoor/Outdoor requirements. Also note that some countries specify the power level as a conducted measurement and others as an EIRP (radiated). The EIRP method also assumes a maximum antenna gain (dBi) and has methods for reducing the maximum if you exceed that particular antenna gain. There is also a difference in some regulatory domains for point-to-point applications vs. client aggregation. Good luck and let me know if you do indeed find an independent single source of information. It would save me a *lot* of time.

Is there a single source of information on the web for this? Thanks, Peter _____ Expecting?
