T-Mobile recently introduced its first smartphones capable of taking advantage of T-Mobile’s faster (HSPA+ 42) network — the Samsung Galaxy S II and HTC Amaze 4G.

T-Mobile made a (marketing) case that it was “4G” because it was combining two channels together to double the speed from a theoredical 21Mbps of HSPA+ to 42 Mbps. T-Mobile says HSPA+ can get 21Mbps by using higher order modulation (64QAM). Bonding two channels gets it to 42Mbps. Under the tower.

T-Mobile is ganging two 5 MHz AWS-band channels together to double the speeds, a “multi-carrier” approach. HSPA+ can theoretically support up to 168 Mbit/s by using multiple carriers with MultiCell and MIMO together simultaneously. Wikipedia compares all the wireless data standards.
