It is derived from 1902 a limitation of the PHY layer, depending on the effective modulation rate used, taking into 1903 account a possible repeater encapsulation layer. The maximum application payload length in 1904 the absence of the OPTIONAL FOpts control field (N) is also given for information only. The 1905 value of N might be smaller if the FOpts field is not empty. 1906 1907 Data Rate M N 0 59 51 1 59 51 2 59 51 3 123 115 4 230 222 5 230 222 7 230 222 12 230 222 13 230 222 6, 8:11 and 14:15 Not defined Table 96: IN865 maximum payload size (repeater compatible) 1908 1909
