Page 12 has throughput table

http://www.itu.int/ITU-D/arb/COE/2009/RuralCommunications/Documents/Doc6-TypesofRegulatoryReform.pdf:2 (27-29 July, 2009) 2.75G has HSPA MIMO, which I think has evolved to HSPA+

Has it that 3.75G is HSOPA; 4G was LTE and WiMAX

But, page 13 describes the parallels of evolution between 2G and 3G on comparable, but different networks (CDMA/TDMA vs GSM)

This explains 3.9G/4G http://www.economist.com/blogs/babbage/2012/01/mobile-telephony

http://www.itu.int/ITU-D/tech/MobileCommunications/IMT_INTRODUCING/IMT_Introducing.html says that fractional G's (generations) are not formal standards, but used for marketing.

http://www.itu.int/en/ITU-T/techwatch/Documents/1010-B_Jamoussi_IoT.pdf:13 Defines some 3.9 standards

3.9G is defined as Ultra Mobile Broadband

3G, 3.5G, 3.75G, 3.9G
The correct breakdown into fractional 3G generations as they correlate to their respective standards is also required, because the lack of any breakdown introduces lots of confusion, especially to non-technical people who can't yet, but really want to correlate marketing terms and standards themselves. (At first I was also confused, but then I got the bright idea of consulting ITU's own literature on the subject.)

If there is any breakdown to be had, it has to be based on official documents, because general-purpose publications (newspapers, journals, et al.) can have plenty of confusion themselves over the differences in terms. Reputable sources confirming the breakdown are welcome.

A little breakdown of what these generations stand for:
