I've been searching around the internet and getting vastly varying information on this topic.
The impression I seem to get is normal HSPA can do 21mbps in the downlink (HSDPA), with dual carrier DC-HSDPA, this can then be doubled to 42mbps.
In terms of HSPA+, I've seen single carrier theoretical speeds of 21mbps, 28mbps and 42 mbps, with dual carrier being double of each respectively.
Would someone be so kind as to explain this. I can merely deduce that there's confusion as a result of HSPA+ being a further iteration of the 3GP standard, rather than a distinct technology.
