The following encoding is used for Data Rate (DR) and End-device EIRP (TXPower) in the 742 EU433 band: 743 744 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 29: EU433 Data rate and TX power table 745 746 EIRP refers to the Equivalent Isotropically Radiated Power, which is the radiated output 747 power referenced to an isotropic antenna radiating power equally in all directions and whose 748 gain is expressed in dBi. 749 750 By default MAxEIRP is considered to be +12.15dBm. If the end-device cannot achieve 751 12.15dBm EIRP, the Max EIRP SHALL be communicated to the network server using an 752 out-of-band channel during the end-device commissioning process. 753 754 755 2.5.4 EU433 JoinAccept CFList 756 757 The EU433 ISM band LoRaWAN implements an optional channel frequency list (CFlist) of 758 16 octets in the JoinAccept message. 759 In this case the CFList is a list of five channel frequencies for the channels three to seven 760 whereby each frequency is encoded as a 24 bits unsigned integer (three octets). All these 761 channels are usable for DR0 to DR5 125 kHz LoRa modulation. The list of frequencies is 762 followed by a single CFListType octet for a total of 16 octets. The CFListType SHALL be equal 763 to zero (0) to indicate that the CFList contains a list of frequencies. 764 765 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 766 frequencies below 100 MHz are reserved for future use. This allows setting the frequency of 767 a channel anywhere between 100 MHz to 1.67 GHz in 100 Hz steps. Unused channels have 768 a frequency value of 0. The CFList is optional and its presence can be detected by the length 769 of the join-accept message. If present, the CFList MUST replace all the previous channels 770 stored in the end-device apart from the three default channels. 771 The newly defined channels are immediately enabled and usable by the end-device for 772 communication. 773
