LoRaWAN® Regional Parameters RP002-1.0.4 ©2022 LoRa Alliance ® Page 51 of 101 The authors reserve the right to change specifications without notice. 965 Example: 966 First pass: Random channel from [0-7], followed by [8-15] … [56-63], 967 then 64. 968 Second pass: Random channel from [0-7], followed by [8-15] … [56-63], 969 then 65. 970 Last pass: Random channel from [0-7], followed by [8-15] … [56-63], 971 then 71. 972 Personalized devices SHALL have all 72 channels enabled following a reset and SHALL use 973 the channels for which the device's default data-rate is valid. 974 The default Join-Request Data Rate SHALL be DR2 (SF10/125 kHz); this setting ensures that 975 end-devices are compatible with the 400ms dwell time limitation until the actual dwell time limit 976 is notified to the end-device by the Network Server via the MAC command 977 TxParamSetupReq. 978 AU915-928 end-devices SHALL consider UplinkDwellTime = 1 during boot stage until 979 reception of the TxParamSetupReq command. 980 AU915-928 end-devices SHALL always consider DownlinkDwellTime = 0, since downlink 981 channels use 500 kHz bandwidth without any dwell time limit. 982 2.8.3 AU915-928 Data Rate and End-Point Output Power Encoding 983 The TxParamSetupReq and TxParamSetupAns MAC commands SHALL be implemented 984 by AU915-928 devices. 985 If the field UplinkDwellTime is set to 1 by the Network Server in the TxParamSetupReq 986 command, AU915-928 end-devices SHALL adjust the time between two consecutive uplink 987 transmissions to meet the local regulations. Twenty seconds (20s) are recommended between 988 two uplink transmissions when UplinkDwellTime = 1 but this value MAY be adjusted 989 depending on local regulations. 990 There is no such constraint on time between two consecutive transmissions when 991 UplinkDwellTime = 0. 992 The following encoding is used for Data Rate (DR) and end-point EIRP (TXPower) in the 993 AU915-928 band: 994 995 Data Rate 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 LR-FHSS CR1/3: 1.523 MHz BW 162 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
