LoRaWAN 1.0.3 Regional Parameters ©2018 LoRa™ Alliance Page 60 of 71 The authors reserve the right to change specifications without notice. The list of frequencies is followed by a single CFListType octet for a total of 16 octets. The 1454 CFListType SHALL be equal to zero (0) to indicate that the CFList contains a list of 1455 frequencies. 1456 1457 Size (bytes) 3 3 3 3 3 1 CFList Freq Ch3 Freq Ch4 Freq Ch5 Freq Ch6 Freq Ch7 CFListType The actual channel frequency in Hz is 100 x frequency whereby values representing 1458 frequencies below 100 MHz are reserved for future use. This allows setting the frequency of 1459 a channel anywhere between 100 MHz to 1.67 GHz in 100 Hz steps. Unused channels have 1460 a frequency value of 0. The CFList is optional and its presence can be detected by the length 1461 of the join-accept message. If present, the CFList replaces all the previous channels stored 1462 in the end-device apart from the three default channels. The newly defined channels are 1463 immediately enabled and usable by the end-device for communication. 1464 2.10.5 IN865-867 LinkAdrReq command 1465 The INDIA 865-867 LoRaWAN only supports a maximum of 16 channels. When ChMaskCntl 1466 field is 0 the ChMask field individually enables/disables each of the 16 channels. 1467 1468 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 72: IN865-867 ChMaskCntl value table 1469 If the ChMaskCntl field value is one of values meaning RFU, the end-device SHOULD reject 1470 the command and unset the "Channel mask ACK" bit in its response. 1471 2.10.6 IN865-867 Maximum payload size 1472 The maximum MACPayload size length (M) is given by the following table. It is derived from 1473 limitation of the PHY layer depending on the effective modulation rate used taking into account 1474 a possible repeater encapsulation layer. The maximum application payload length in the 1475 absence of the optional FOpt control field (N) is also given for information only. The value of 1476 N might be smaller if the FOpt field is not empty: 1477 1478 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
