LoRaWAN 1.0.3 Regional Parameters ©2018 LoRa™ Alliance Page 44 of 71 The authors reserve the right to change specifications without notice. Personalized devices SHALL have all 96 channels enabled following a reset. 1055 1056 2.7.3 CN470-510 Data Rate and End-point Output Power encoding 1057 There is no dwell time limitation for the CN470-510 PHY layer. The TxParamSetupReq MAC 1058 command is not implemented by CN470-510 devices. 1059 The following encoding is used for Data Rate (DR) and End-point EIRP (TXPower) in the 1060 CN470-510 band: 1061 1062 DataRate Configuration Indicative physical bit rate [bit/sec] 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..15 RFU 6 Max EIRP – 12dB 7 Max EIRP – 14dB 8…15 RFU Table 42: CN470-510 Data rate and TX power table 1063 1064 EIRP refers to the Equivalent Isotropically Radiated Power, which is the radiated output 1065 power referenced to an isotropic antenna radiating power equally in all directions and whose 1066 gain is expressed in dBi. 1067 1068 By default MaxEIRP is considered to be +19.15dBm. If the end-device cannot achieve 1069 19.15dBm EIRP, the Max EIRP SHOULD be communicated to the network server using an 1070 out-of-band channel during the end-device commissioning process. 1071 1072 2.7.4 CN470-510 JoinResp CFList 1073 1074 The CN470-510 LoRaWAN supports the use of the optional CFlist appended to the 1075 JoinResp message. If the CFlist is not empty then the CFListType field SHALL contain the 1076 value one (0x01) to indicate the CFList contains a series of ChMask fields. The ChMask 1077 fields are interpreted as being controlled by a virtual ChMaskCntl that initializes to a value of 1078 zero (0) and increments for each ChMask field to a value of five (5). (The first 16 bits 1079 controls the channels 1 to 16, ..) 1080 1081 Size (bytes) [2] [2] [2] [2] [2] [2] [3] [1] CFList ChMask0 ChMask1 ChMask2 ChMask3 ChMask4 ChMask5 RFU CFListType 2.7.5 CN470-510 LinkAdrReq command 1082 For the CN470-510 version the ChMaskCntl field of the LinkADRReq command has the 1083 following meaning: 1084 1085
