LoRaWAN 1.0.3 Regional Parameters ©2018 LoRa™ Alliance Page 34 of 71 The authors reserve the right to change specifications without notice. 2.5.5 EU433 LinkAdrReq command 774 The EU433 LoRaWAN only supports a maximum of 16 channels. When ChMaskCntl field is 775 0 the ChMask field individually enables/disables each of the 16 channels. 776 777 ChMaskCntl ChMask applies to 0 Channels 0 to 15 1 RFU .. .. 4 RFU 5 RFU 6 All channels ON The device SHOULD enable all currently defined channels independently of the ChMask field value. 7 RFU Table 30: EU433 ChMaskCntl value table 778 If the ChMask field value is one of the values meaning RFU, then end-device SHALL reject 779 the command and unset the "Channel mask ACK" bit in its response. 780 2.5.6 EU433 Maximum payload size 781 The maximum MACPayload size length (M) is given by the following table. It is derived from 782 limitation of the PHY layer depending on the effective modulation rate used taking into account 783 a possible repeater encapsulation layer. The maximum application payload length in the 784 absence of the optional FOpt control field (N) is also given for information only. The value of 785 N might be smaller if the FOpt field is not empty: 786 787 DataRate M N 0 59 51 1 59 51 2 59 51 3 123 115 4 230 222 5 230 222 6 230 222 7 230 222 8:15 Not defined Table 31: EU433 maximum payload size 788 789 If the end-device will never operate with a repeater then the maximum application payload 790 length in the absence of the optional FOpt control field SHOULD be: 791 792 DataRate 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 8:15 Not defined
