It is derived from 688 a limitation of the PHY layer, depending on the effective modulation rate used, taking into 689 account a possible repeater encapsulation layer. The maximum application payload length in 690 the absence of the OPTIONAL FOpts control field (N) is also given for information only. The 691 value of N MAY be smaller if the FOpts field is not empty. 692 693 Data Rate M N 0 59 51 1 59 51 2 59 51 3 123 115 4 230 222 5 230 222 6 230 222 7 230 222 8 58 50 9 123 115 10 58 50 11 123 115 12 230 222 13 230 222 14..15 Not defined Table 15: EU863-870 maximum payload size (repeater compatible) 694 If the end-device will never operate with a repeater, the maximum application payload length 695 in the absence of the OPTIONAL FOpts control field SHALL be: 696 697 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 12 250 242 13 250 242 14..15 Not defined Table 16: EU863-870 maximum payload size (not repeater compatible) 698 3.4.7 EU863-870 Receive Windows 699 By default, the RX1 receive window uses the same channel as the preceding uplink. The data 700 rate is a function of the uplink data rate and the RX1DROffset, as given by the following 701 table. The allowed values for RX1DROffset are in the [0:5] range. Values in the [6:7] range 702 are reserved for future use and end-devices SHALL NOT accept these settings in any 703 command, neither a RXParamSetupReq, which SHALL cause a negative acknowledgement 704
