When the device is using the Adaptive Data Rate mode and transmits using the DRcurrent 1158 uplink data rate, the following table defines the next uplink data rate (DRnext) the end-device 1159 SHALL use during data rate back-off: 1160 UplinkDwellTime=0 UplinkDwellTime=1 DRcurrent DRnext DRcurrent DRnext 0 NA NA NA 1 0 NA NA 2 1 2 NA 3 2 3 2 4 3 4 3 5 4 5 4 6 5 6 5 7 0 7 2 9 5 9 5 10 9 10 9 Table 41: AU915-928 uplink data rate back-off 1161 1162 Transmit power levels relative to the maximum EIRP level of the end-device are indicated in 1163 the following TXPower table: 1164 1165 TXPower Configuration (EIRP) 0 Max EIRP 1:14 Max EIRP – 2*TXPower 15 Defined in [TS001] 3 Table 42: AU915-928 TXPower 1166 EIRP refers to the Effective Isotropic Radiated Power, which is the radiated output power 1167 referenced to an isotropic antenna radiating power equally in all directions and whose gain is 1168 expressed in dBi. 1169 By default, the Max EIRP of the end-device is considered to be +30dBm. End-devices 1170 operating in countries allowing different EIRP than the default value MAY adapt their default 1171 Max EIRP accordingly, but they SHALL NOT exceed the maximum EIRP imposed by the local 1172 regulations. If the end-device does not use the default value (+30dBm), the Max EIRP 1173 SHOULD be communicated to the Network Server using an out-of-band channel during the 1174 end-device commissioning process. 1175 The Max EIRP of the end-device can be modified by the Network Server through the 1176 TxParamSetupReq MAC command and SHALL be used by both the end-device and the 1177 Network Server as shown in Table 42 once TxParamSetupReq is acknowledged by the end- 1178 device via TxParamSetupAns. 1179 3.8.4 AU915-928 Join-Accept CFList 1180 The AU915-928 LoRaWAN supports the use of the OPTIONAL CFlist appended to the Join- 1181 Accept message. If the CFlist is not empty, the CFListType field SHALL contain the value 1182 one (0x01) to indicate the CFList contains a series of ChMask fields as defined in 2.3.2. 1183 Channel-ID values from 0 to 71 are supported and SHALL be interpreted as the 1184 channel number to be enabled or disabled. A cleared bit in the CFList SHALL disable 1185 the associated channel. All bits corresponding to Channel-ID values above 71 are 1186 RFU. 1187
