It is derived from 816 the maximum allowed transmission time at the PHY layer taking into account a possible 817 repeater encapsulation. The maximum application payload length in the absence of the 818 optional FOpt MAC control field (N) is also given for information only. The value of N might 819 be smaller if the FOpt field is not empty: 820 821 DataRate M N 0 59 51 1 59 51 2 59 51 3 123 115 4 230 222 5 230 222 6 230 222 7 Not defined 8 41 33 9 117 109 10 230 222 11 230 222 12 230 222 13 230 222 14:15 Not defined Table 37: AU915-928 maximum payload size 822 The greyed lines correspond to the data rates that may be used by an end-device behind a 823 repeater. 824 If the end-device will never operate with a repeater then the maximum application payload 825 length in the absence of the optional FOpt control field should be: 826 827
