Radio Settings

Link ID

Wireless link identificator used to avoid connecting a unit to a wrong peer if there are several co-located units using the same center frequency. Specify different ID values for different links. Both ends of the same link must have the same ID.

Center frequency

Set the radio interface frequency (in MHz).

Must be the same at both ends of the link.

Channel Width

Set the bandwidth of the radio interface in MHz.

Must be the same at both ends of the link.

Power limit

Set the output power of the radio interface in dBm. Available values 0...27 dBm.

Cable loss

In case of external antenna usage, energy fading on cables should be set in accordance to the cable datasheet, in dB.

Antenna gain

In case of external antenna usage, it's gain should be set manually in dBi.

Automatic transmission power control (ATPC)

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. We highly recommend to always keep it turned on.

Target RSSI

RSSI value in dBm will be used by ATPC of remote device as target. Optimal values -60...-40 dBm.

Automatic modulation control (AMC)

Modulation control algorithm selects the most appropriate modulation-coding scheme at each direction in order to maximize the link performance.

By default, it is turned on (it is strongly recommended to remains “on”).

Modulation limit

Set the maximum operating modulation scheme of the radio interface.

Acts as a top limit for the modulation if the Autobitrate mechanism is turned on.
