DR0 and a random 500 kHz channel amongst the 8 channels defined using DR6. The end- 781 device should change channel for every transmission. 782 Personalized devices shall have all 72 channels enabled following a reset. 783 2.5.3 AU915-928 Data Rate and End-point Output Power encoding 784 The TxParamSetupReq MAC command is not implemented by AU915-928 devices. 785 The following encoding is used for Data Rate (DR) and End-point EIRP (TXPower) in the 786 AU915-928 band: 787 788 DataRate Configuration Indicative physical bit rate [bit/sec] 0 LoRa: SF12 / 125 kHz 250 1 LoRa: SF11 / 125 kHz 440 2 LoRa: SF10 / 125 kHz 980 3 LoRa: SF9 / 125 kHz 1760 4 LoRa: SF8 / 125 kHz 3125 5 LoRa: SF7 / 125 kHz 5470 6 LoRa: SF8 / 500 kHz 12500 7 RFU 8 LoRa: SF12 / 500 kHz 980 9 LoRa: SF11 / 500 kHz 1760 10 LoRa: SF10 / 500 kHz 3900 11 LoRa: SF9 / 500 kHz 7000 12 LoRa: SF8 / 500 kHz 12500 13 LoRa: SF7 / 500 kHz 21900 14:15 RFU Table 34: AU915-928 Data rate table 789 790 DR6 is identical to DR12, DR8...13 must be implemented in end-devices and are reserved 791 for future applications. 792 793 TXPower Configuration (EIRP) 0 MaxEIRP 1:10 MaxEIRP – 2*TXPower 11:15 RFU Table 35 : AU915-928 TX power table 794 795 EIRP refers to the Equivalent Isotropically Radiated Power, which is the radiated output 796 power referenced to an isotropic antenna radiating power equally in all directions and whose 797 gain is expressed in dBi. 798 799 By default MaxEIRP is considered to be +30dBm. If the end-device cannot achieve 30dBm 800 EIRP, the Max EIRP should be communicated to the network server using an out-of-band 801 channel during the end-device commissioning process. 802 803 2.5.4 AU915-928 JoinAccept CFList 804 The AU915-928 LoRaWAN does not support the use of the optional CFlist appended to the 805 JoinAccept message. If the CFlist is not empty it is ignored by the end-device. 806
