Basically, HSPA is a collection of two main technologies HSDPA and HSUPA.

Airtel people are very clever, they are marketting as "HSPA" just to gather attention, whereas BSNL is simply marketting as HSDPA.

Practically, there isn't any difference IMO. Just a gimmick by the 'clever' Airtel. Go for the one which has the better plans.
