RP002-1.0.0 LoRaWAN Regional Parameters ©2019 LoRa Alliance ® Page 80 of 88 The authors reserve the right to change specifications without notice. Size (bytes) 3 3 3 3 3 1 CFList Freq Ch2 Freq Ch3 Freq Ch4 Freq Ch5 Freq Ch6 CFListType 1624 The actual channel frequency in Hz is 100 x frequency whereby values representing 1625 frequencies below 100 MHz are reserved for future use. This allows setting the frequency of 1626 a channel anywhere between 100 MHz to 1.67 GHz in 100 Hz steps. Unused channels have 1627 a frequency value of 0. The CFList is OPTIONAL and its presence can be detected by the 1628 length of the join-accept message. If present, the CFList replaces all the previous channels 1629 stored in the end-device apart from the two default channels. The newly defined channels are 1630 immediately enabled and usable by the end-device for communication. 1631 2.13.5 RU864-870 LinkAdrReq command 1632 The RU864-870 LoRaWAN only supports a maximum of 16 channels. When ChMaskCntl 1633 field is 0 the ChMask field individually enables/disables each of the 16 channels. 1634 1635 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 90: RU864-870 ChMaskCntl value table 1636 If the ChMaskCntl field value is one of values meaning RFU, the end-device SHALL 1 reject 1637 the command and unset the "Channel mask ACK" bit in its response. 1638 2.13.6 RU864-870 Maximum payload size 1639 The maximum MACPayload size length (M) is given by the following table. It is derived from 1640 limitation of the PHY layer depending on the effective modulation rate used taking into account 1641 a possible repeater encapsulation layer. The maximum application payload length in the 1642 absence of the OPTIONAL FOpt control field (N) is also given for information only. The value 1643 of N might be smaller if the FOpt field is not empty: 1644 1 Made SHALL from SHOULD starting in LoRaWAN Regional Parameters Specification 1.0.3rA
