If the end-device will never operate with a repeater, the maximum application payload length 623 in the absence of the OPTIONAL FOpts control field SHALL be: 624 625 Data Rate M N 0 59 51 1 59 51 2 59 51 3 123 115 4 250 242 5 250 242 6 250 242 7 250 242 8 58 50 9 123 115 10 58 50 11 123 115 12:15 Not defined Table 13 : EU863-870 maximum payload size (not repeater compatible) 626 2.4.7 EU863-870 Receive Windows 627 By default, the RX1 receive window uses the same channel as the preceding uplink. The data 628 rate is a function of the uplink data rate and the RX1DROffset, as given by the following 629 table. The allowed values for RX1DROffset are in the [0:5] range. Values in the [6:7] range 630 are reserved for future use. 631 632 Upstream Data Rate Downstream Data Rate in RX1 Slot RX1DROffset 0 1 2 3 4 5 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 DR8 DR1 DR0 DR0 DR0 DR0 DR0 DR9 DR2 DR1 DR0 DR0 DR0 DR0 DR10 DR1 DR0 DR0 DR0 DR0 DR0 DR11 DR2 DR1 DR0 DR0 DR0 DR0 Table 14: EU863-870 downlink RX1 data rate mapping 633 The RX2 receive window uses a fixed frequency and data rate.
