 This will allow theoretical speed of up to 84.4 Mbit/s.The following table is derived from table 5.1a of the release 11 of 3GPP TS 25.306 and shows maximum data rates of different device classes and by what combination of features they are achieved.The per-cell per-stream data rate is limited by the "Maximum number of bits of an HS-DSCH transport block received within an HS-DSCH TTI" and the "Minimum inter-TTI interval".
