The following encoding is used for Data Rate (DR) and End-device EIRP (TXPower) in the 628 CN780 band: 629 630 DataRate Configuration Indicative physical bit rate [bit/s] TXPower Configuration (EIRP) 0 LoRa: SF12 / 125 kHz 250 0 Max EIRP 1 LoRa: SF11 / 125 kHz 440 1 Max EIRP – 2dB 2 LoRa: SF10 / 125 kHz 980 2 Max EIRP – 4dB 3 LoRa: SF9 / 125 kHz 1760 3 Max EIRP – 6dB 4 LoRa: SF8 / 125 kHz 3125 4 Max EIRP – 8dB 5 LoRa: SF7 / 125 kHz 5470 5 Max EIRP – 10dB 6 LoRa: SF7 / 250 kHz 11000 6..15 RFU 7 FSK: 50 kbps 50000 8..15 RFU Table 21: CN779-787 Data rate and TX power table 631 632 EIRP refers to the Equivalent Isotropically Radiated Power, which is the radiated output 633 power referenced to an isotropic antenna radiating power equally in all directions and whose 634 gain is expressed in dBi. 635 636 By default MAxEIRP is considered to be +12.15dBm. If the end-device cannot achieve 637 12.15dBm EIRP, the Max EIRP SHOULD be communicated to the network server using an 638 out-of-band channel during the end-device commissioning process. 639 640 2.4.4 CN779-787 JoinAccept CFList 641 The CN780 ISM band LoRaWAN implements an optional channel frequency list (CFlist) of 642 16 octets in the JoinAccept message. 643 In this case the CFList is a list of five channel frequencies for the channels three to seven 644 whereby each frequency is encoded as a 24 bits unsigned integer (three octets). All these 645 channels are usable for DR0 to DR5 125kHz LoRa modulation. The list of frequencies is 646 followed by a single CFListType octet for a total of 16 octets. The CFListType SHALL be equal 647 to zero (0) to indicate that the CFList contains a list of frequencies. 648 649 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 650 frequencies below 100 MHz are reserved for future use. This allows setting the frequency of 651 a channel anywhere between 100 MHz to 1.67 GHz in 100 Hz steps. Unused channels have 652 a frequency value of 0. The CFList is optional and its presence can be detected by the length 653 of the join-accept message. If present, the CFList SHALL replace all the previous channels 654 stored in the end-device apart from the three default channels. 655 The newly defined channels are immediately enabled and usable by the end-device for 656 communication. 657
