A number of parameters must be configured appropriately to reach the maximum data
rate supported by a UE. Use the wizard for this purpose, see
MAC-hs / MAC-ehs selection
The WCDMA signaling application sets up an HSPA connection with MAC-hs or MAC-
ehs, depending on the HSDPA UE category (manually configured UE category or high-
est UE category from capability report).
For UE category 1 to 12 the connection is set up with MAC-hs, bit aligned. For UE cat-
egory 13 to 28 the connection is set up with MAC-ehs, either bit aligned for R5 fixed
reference channels or octet aligned otherwise. The following table provides an over-
view of these statements.

H-set selection for fixed reference channels
For HSDPA fixed reference channels the configured H-set must be compatible to the
HSDPA UE category (see
). The following tables provides an
overview of the H-sets.
