خود hsdpa+ تکنولوژی های مختلفی داره و سرعتش تا بالای 300 مگ هم می تونه بستگی به شرایط محیط و تجهیزات افزایش پیدا کنه
HSPA+HSPA+ is the pinnacle of current 3G technology, offering a theoretical 168Mbit/s downlink speed. In reality most HSPA+ coverage is only capable of 21Mbit/s, with some areas being upgraded to 42Mbit/s and occasionally even 84Mbit/s. But even the fastest implementation of HSPA+ is a long way behind the 1Gbit/s download speed required to be considered a real 4G network. But this hasn’t stopped a number of US carriers from advertising HSPA+ as 4G.T-Mobile was one of the first companies to falsely advertise its HSPA+ network as 4G, and AT&T followed suit shortly after. Arguably AT&T is even worse, as its network started out with capabilities peaking at 14.4Mbit/s download and 5.8Mbit/s upload speeds, which is ridiculously slow for a 4G network. Users in the UK, and some other countries, will probably have noticed that some carriers actually offer HSPA+ as part of their 3G network packages. So it seems that US consumers are being sold and overcharged to use a slower network under the guise of a next generation technology.
