LoRaWAN 1.0.3 Regional Parameters ©2018 LoRa™ Alliance Page 37 of 71 The authors reserve the right to change specifications without notice. 2.6 AU915-928MHz ISM Band 829 830 This section defines the regional parameters for Australia and all other countries whose ISM 831 band extends from 915 to 928MHz spectrum. 832 833 2.6.1 AU915-928 Preamble Format 834 The following synchronization words SHOULD be used: 835 836 Modulation Sync word Preamble length LORA 0x34 8 symbols LoRaWAN does not make use of GFSK modulation in the AU915-928 ISM band. 837 2.6.2 AU915-928 Channel Frequencies 838 The AU ISM Band SHALL be divided into the following channel plans. 839 • Upstream – 64 channels numbered 0 to 63 utilizing LoRa 125 kHz BW varying from 840 DR0 to DR5, using coding rate 4/5, starting at 915.2 MHz and incrementing linearly 841 by 200 kHz to 927.8 MHz 842 • Upstream – 8 channels numbered 64 to 71 utilizing LoRa 500 kHz BW at DR6 843 starting at 915.9 MHz and incrementing linearly by 1.6 MHz to 927.1 MHz 844 • Downstream – 8 channels numbered 0 to 7 utilizing LoRa 500 kHz BW at DR8 to 845 DR13) starting at 923.3 MHz and incrementing linearly by 600 kHz to 927.5 MHz 846 847 848 Figure 2: AU915-928 channel frequencies 849 AU ISM band end-devices may use a maximum EIRP of +30 dBm. 850 AU915-928 end-devices SHALL be capable of operating in the 915 to 928 MHz frequency 851 band and SHALL feature a channel data structure to store the parameters of 72 channels. A 852 channel data structure corresponds to a frequency and a set of data rates usable on this 853 frequency. 854 If using the over-the-air activation procedure, the end-device SHALL broadcast the JoinReq 855 message alternatively on a random 125 kHz channel amongst the 64 channels defined using 856 DR2 and a random 500 kHz channel amongst the 8 channels defined using DR6. The end- 857 device SHOULD change channel for every transmission. 858 Personalized devices SHALL have all 72 channels enabled following a reset. 859 860 The default JoinReq Data Rate is DR2 (SF10/125KHz), this setting 861 ensures that end-devices are compatible with the 400ms dwell time 862 limitation until the actual dwell time limit is notified to the end-device by 863 the network server via the MAC command TxParamSetupReq. 864
