7. Radio Settings
The radio settings available depend upon the modulation, denoted Mod in the sub-menu Radio Settings. For each
modem you can modify the modulation and power parameters. The registered settings are proper to each
modulation.
7.1.
LORA Modulation
The radio settings available for LORA modulation are:
-
The Frequency (Freq) as described in
-
The Transmission Power (Tx Pow): in steps of 1 dBm between -18 dBm and
+13 dBm
-
Param 1: choose a Spreading Factor between SF5 and SF10
-
Param 2 : choose a BandWidth (BW) of either 400 kHz, 800 kHz or 1.6 MHz
-
Param 3: The Coding Rate (CR) of the Forward Error Correction applied to
the packet, of either CR 4/5, 4/6,4/7, 4/8 or CRLI 4/5, 4/6, 4/7
-
Payload: size of the payload between 12 and 248 bytes
7.2.
FLRC Modulation
The radio settings available for FLRC modulation are:
-
The Frequency (Freq) as described in
-
The Transmission Power (Tx Power): in steps of 1 dBm between -18 dBm
and +13 dBm
-
Param 1: choose a data rate and an associated bandwidth (BW)
-
Param 2 : The Coding Rate (CR) of the Forward Error Correction applied to
the packet, of either 1, ½ or 3/4
-
Param 3: Bandwidth-Time bit period product (BT) of either 1, 0.5 or OFF
-
Payload: size of the payload between 12 and 120 bytes
