| AMC strategy | There are folowing 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.
| | Automatic transmit power control | ATPC allows to control transmitter output power automatically. Each unit has its own target RSSI level value calculated automatically. 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.

Frequency channel grids
Each available channel width is connected with appropriate channel grid. Grid is used for automatic center frequency selection function and contains a list of frequencies which can that may be selected. In the example below you may see that wireless unit with enabled "Automatic center frequency selection" may change center frequency to the following values (MHz): 5100, 5120, 5140, 5300, 5390, 5410.

| 5100-5140/20, 5300, 5390-5410/20 |
|
Each element of list may be set as follows:
- 5300 - exact value;
- 5100-5140/20, 5390-5410/20 - range of values with 20 MHz step.
