The RX1 receive channel can be determined as follows. 831 o RX1 Channel Number = Transmit Channel Number modulo 8 832 The RX1 window data rate depends on the transmit data rate (see Table 16 below). 833 The RX2 (second receive window) settings uses a fixed data rate and frequency. 834 Default parameters are 923.3Mhz / DR8 835 836 Upstream data rate Downstream data rate RX1DROff set 0 1 2 3 4 5 DR0 DR8 DR8 DR8 DR8 DR8 DR8 DR1 DR9 DR8 DR8 DR8 DR8 DR8 DR2 DR10 DR9 DR8 DR8 DR8 DR8 DR3 DR11 DR10 DR9 DR8 DR8 DR8 DR4 DR12 DR11 DR10 DR9 DR8 DR8 DR5 DR13 DR12 DR11 DR10 DR9 DR8 DR6 DR13 DR13 DR12 DR11 DR10 DR9 Table 39 : AU915-928 downlink RX1 data rate mapping 837 838 The allowed values for RX1DROffset are in the [0:5] range. Values in the range [6:7] are 839 reserved for future use. 840 841 2.5.8 AU915-928 Class B beacon 842 The beacons are transmitted using the following settings: 843 DR 10 Corresponds to SF10 spreading factor with 500kHz bw CR 1 Coding rate = 4/5 Signal polarity Non-inverted As opposed to normal downlink traffic which uses inverted signal polarity frequencies 923.3 to 927.5MHz with 600kHz steps Beaconing is performed on the same channel that normal downstream traffic as defined in
