7.5.3 Automatic modulation and transmit power control
Parameter Description
AMC
strategy
There are following AMC strategies available:
Normal - represents a balance between the error rate and throughput values.
Conservative - assumes using higher CINR thresholds in order to minimize the error rate.
Agressive - lowers the thresholds in order to use higher modulation levels and thus increase
the throughput but also increase the error rate.
Extreme - lowers the CINR threshold below the Aggressive strategy values in order to
maximize selected modulation and throughput.
Automatic
transmit
power
control
ATPC allows to control transmitter output power automatically based on target RSSI value. If
actual RSSI level is lower then unit increases transmitter output power of the remote unit and
vice versa. ATPC could not set value that may exceed the "Power limit" value.
The Master unit manages the transmit power of Slave unit.
The Slave unit manages the transmit power of Master unit.
Target RSSI RSSI value which will be used by ATPC as target.

7.5.4 Frequency channel grids
The frequency grid allows to limit the scan range in case the center frequency is automatically selected. AlsoInstant
DFSwill use these restrictions when monitoring the noise situation. Narrow grid of available frequencies speeds up
scanning and link establishing process. Manual center frequency selection will also be limited to the values
indicated in the grid.
