The data rate is 7 a function of the uplink data rate and the RX1DROffset as given by the following table. The 8 allowed values for RX1DROffset are in the [0:5] range. Values in the [6:7] range are 9 reserved for future use. 10 11 12 RX1DROffset 0 1 2 3 4 5 Upstream data rate Downstream data rate in RX1 slot DR0 DR0 DR0 DR0 DR0 DR0 DR0 DR1 DR1 DR0 DR0 DR0 DR0 DR0 DR2 DR2 DR1 DR0 DR0 DR0 DR0 DR3 DR3 DR2 DR1 DR0 DR0 DR0 DR4 DR4 DR3 DR2 DR1 DR0 DR0 DR5 DR5 DR4 DR3 DR2 DR1 DR0 DR6 DR6 DR5 DR4 DR3 DR2 DR1 DR7 DR7 DR6 DR5 DR4 DR3 DR2 13 The RX2 receive window uses a fixed frequency and data rate.
