LoRaWAN 1.0.2 Regional Parameters ©2017 LoRa Alliance™ Page 10 of 55 The authors reserve the right to change specifications without notice. By default MaxEIRP is considered to be +16dBm. If the end-device cannot achieve 16dBm 305 EIRP, the Max EIRP should be communicated to the network server using an out-of-band 306 channel during the end-device commissioning process. 307 308 2.1.4 EU863-870 JoinAccept CFList 309 310 The EU 863-870 ISM band LoRaWAN implements an optional channel frequency list 311 (CFlist) of 16 octets in the JoinAccept message. 312 In this case the CFList is a list of five channel frequencies for the channels four to eight 313 whereby each frequency is encoded as a 24 bits unsigned integer (three octets). All these 314 channels are usable for DR0 to DR5 125kHz LoRa modulation. The list of frequencies is 315 followed by a single RFU octet for a total of 16 octets. 316 317 Size (bytes) 3 3 3 3 3 1 CFList Freq Ch4 Freq Ch5 Freq Ch6 Freq Ch7 Freq Ch8 RFU The actual channel frequency in Hz is 100 x frequency whereby values representing 318 frequencies below 100 MHz are reserved for future use. This allows setting the frequency of 319 a channel anywhere between 100 MHz to 1.67 GHz in 100 Hz steps. Unused channels have 320 a frequency value of 0. The CFList is optional and its presence can be detected by the 321 length of the join-accept message. If present, the CFList replaces all the previous channels 322 stored in the end-device apart from the three default channels. The newly defined channels 323 are immediately enabled and usable by the end-device for communication. 324 2.1.5 EU863-870 LinkAdrReq command 325 The EU863-870 LoRaWAN only supports a maximum of 16 channels. When ChMaskCntl 326 field is 0 the ChMask field individually enables/disables each of the 16 channels. 327 328 ChMaskCntl ChMask applies to 0 Channels 1 to 16 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 6: ChMaskCntl value table 329 If the ChMaskCntl field value is one of values meaning RFU, the end-device should reject 330 the command and unset the "Channel mask ACK" bit in its response. 331 2.1.6 EU863-870 Maximum payload size 332 The maximum MACPayload size length (M) is given by the following table. It is derived from 333 limitation of the PHY layer depending on the effective modulation rate used taking into 334 account a possible repeater encapsulation layer.
