3G -> 3.9G


There seems to be confusion when people discuss terms like 3.5G, 3.75G so i decided to define them. I am sure people who have objections will comment.
Lets first start with 2G systems:
2G = GSM
2.5G = GPRS
2.75G = EDGE
Then moving onto 3G systems:
3G = WCDMA, R99 (i am not looking at other technologies but similar mapping will apply)
3.5G = HSDPA
3.75G = HSUPA
3.8G = HSPA+ (HSPA Enhancements)
3.85G = 'HSPA+' + MIMO
3.9G = LTE
4G = NOT WiMAX
