A 1597 channel data structure corresponds to a frequency and a set of data rates usable on this 1598 frequency. 1599 The first three channels correspond to 865.0625, 865.4025, and 865.985 MHz / DR0 to DR5 1600 and SHALL be implemented in every end-device. For devices compliant with [TS001-1.0.x], 1601 those default channels SHALL NOT be modified through the NewChannelReq command. For 1602 devices compliant with [TS001-1.1.x] and beyond, these channels MAY be modified through 1603 the NewChannelReq command but SHALL be reset during the back-off procedure defined in 1604 [TS001] to guarantee a minimal common channel set between end-devices and network 1605 gateways. 1606 The following table gives the list of frequencies that SHALL be used by end-devices to 1607 broadcast the Join-Request message. The Join-Request message transmit duty-cycle SHALL 1608 follow the rules described in chapter "Retransmissions back-off" of the LoRaWAN [TS001] 1609 specification document. 1610 1611 Modulation Bandwidth [kHz] Channel Frequency [MHz] LoRa DR / Bitrate Number of Channels LoRa 125 865.0625 865.4025 865.9850 DR0 – DR5 / 0.3-5 kbps 3 Table 78: IN865-867 Join-Request channel list 1612 2.12.3 IN865-867 Data Rate and End-Device Output Power Encoding 1613 There is no dwell time or duty-cycle limitation for the INDIA 865-867 PHY layer. The 1614 TxParamSetupReq MAC command is not implemented by INDIA 865-867 devices. 1615 The following encoding is used for Data Rate (DR) and end-device output power (TXPower) 1616 in the INDIA 865-867 band: 1617 Data Rate Configuration Indicative Physical Bit Rate [bit/s] 0 LoRa: SF12 / 125 kHz 250 1 LoRa: SF11 / 125 kHz 440 2 LoRa: SF10 / 125 kHz 980 3 LoRa: SF9 / 125 kHz 1760 4 LoRa: SF8 / 125 kHz 3125 5 LoRa: SF7 / 125 kHz 5470 6 RFU RFU 7 FSK: 50 kbps 50000 8..14 RFU 15 Defined in [TS001] 33 Table 79: IN865-867 TX data rate 1618 33 DR15 and TXPower15 are defined in the LinkADRReq MAC command of the LoRaWAN1.0.4 and subsequent specifications and were previously RFU.
