Setting up the Power Levels for each available Standard
The second configuration step defines power levels for each standard and modulation, whereas
the modulation of standard b and standard g is defined by the related data rates. There are
11 bytes for applying the configuration with some configurations merged to one byte. Bytes
txpwr_index_0 to txpwr_index_7 are stored at byte positions "58" to "65" and correspond
to standard 802.11g and standard 802.11n. The power is defined by the index of the desired
power value txpwr_gdb.
For configuring the power levels of standard 802.11b, there are two possibilities:
•
Set byte txpwr_index_11b_en at byte position "66" to zero. This makes
txpwr_qdb_0 to be used for all 802.11b data rates.
•
Set byte txpwr_index_11b_en to one. txpwr_index_11b_0 and
txpwr_index_11b_1 define the maximum power levels.
Configurations that fulfill the requirements for a valid modular approval are given in the following
table. The configuration requires the power values to be configured as described in
6.1.2 Limiting the Output
