Frame Profile The Frame Profile controls the amount
of time allocated to the downlink and
uplink portions of the WiMAX frame. To
operate in a WiMAX compatible mode,
choose one of the specific profiles for
the chosen RF bandwidth. The Frame
Profile can also be set to None. When
set to None, the user can set a specific
percentage for the downlink sub-frame.
