The TxParamSetupReq MAC 854 command is not implemented by EU433 devices. 855 The following encoding is used for Data Rate (DR) and end-device EIRP (TXPower) in the 856 EU433 band: 857 858 Data Rate Configuration Indicative Physical Bit Rate [bit/s] TXPower Configuration (EIRP) 0 LoRa: SF12 / 125 kHz 250 0 Max EIRP 1 LoRa: SF11 / 125 kHz 440 1 Max EIRP – 2dB 2 LoRa: SF10 / 125 kHz 980 2 Max EIRP – 4dB 3 LoRa: SF9 / 125 kHz 1760 3 Max EIRP – 6dB 4 LoRa: SF8 / 125 kHz 3125 4 Max EIRP – 8dB 5 LoRa: SF7 / 125 kHz 5470 5 Max EIRP – 10dB 6 LoRa: SF7 / 250 kHz 11000 6..14 RFU 7 FSK: 50 kbps 50000 8..14 RFU 15 Defined in [TS001] 24 15 Defined in [TS001] 24 Table 24: EU433 data rate and TXPower 859 EU433 end-devices SHALL support one of the two following data rate options: 860 1. DR0 to DR5 (minimum set supported for certification) 861 2. DR0 to DR7 862 863 For both options, all data rates in the range specified SHALL be implemented (meaning no 864 intermediate DR may be left unimplemented). 865 When the device is using the Adaptive Data Rate mode and transmits using the DRcurrent 866 data rate, the following table defines the next data rate (DRnext) the end-device SHALL use 867 during data rate back-off: 868 DRcurrent DRnext Comment 0 NA Already the lowest data rate 1 0 2 1 3 2 4 3 5 4 6 5 7 6 Table 25: EU433 data rate back-off 869 EIRP refers to the Equivalent Isotropically Radiated Power, which is the radiated output power 870 referenced to an isotropic antenna radiating power equally in all directions and whose gain is 871 expressed in dBi. 872 By default, the Max EIRP is considered to be +12 dBm. If the end-device cannot achieve 12 873 dBm EIRP, the Max EIRP SHALL be communicated to the Network Server using an out-of- 874 band channel during the end-device commissioning process. 875 24 DR15 and TXPower15 are defined in the LinkADRReq MAC command of the LoRaWAN 1.0.4 and subsequent specifications and were previously RFU.
