It is derived from 1403 the maximum allowed transmission time at the PHY layer, taking into account a possible 1404 repeater encapsulation. The maximum application payload length in the absence of the 1405 OPTIONAL FOpts MAC control field (N) is also given for information only. The value of N 1406 might be smaller if the FOpts field is not empty. 1407 Data Rate M N 0 15 N/A N/A 1 31 23 2 94 86 3 192 184 4 230 222 5 230 222 6 230 222 7 230 222 8:15 Not defined Table 54: CN470-510 maximum payload size (repeater compatible) 1408 If the end-device will never operate with a repeater, the maximum application payload length 1409 in the absence of the OPTIONAL FOpts control field SHALL be: 1410 Data Rate M N 0 15 N/A N/A 1 31 23 2 94 86 3 192 184 4 250 242 5 250 242 6 250 242 7 250 242 8:15 Not defined Table 55: CN470-510 maximum payload size (not repeater compatible) 1411 1412
