IN865-867 end-devices SHALL support one of the two following data rate options: 1619 1. DR0 to DR5 (minimum set supported for certification) 1620 2. DR0 to DR6 and DR7 1621 For both options, all data rates in the range specified SHALL be implemented (meaning no 1622 intermediate DR may be left unimplemented). 1623 When the device is using the Adaptive Data Rate mode and transmits using the DRcurrent 1624 data rate, the following table defines the next data rate (DRnext) the end-device SHALL use 1625 during data rate back-off: 1626 DRcurrent DRnext Comment 0 NA Already the lowest data rate 1 0 2 1 3 2 4 3 5 4 7 5 Table 80: IN865-867 data rate back-off 1627 The TXPower table indicates power levels relative to the Max EIRP level of the end-device, 1628 as per the following table: 1629 1630 TXPower Configuration (EIRP) 0 Max EIRP 1 Max EIRP – 2dB 2 Max EIRP – 4dB 3 Max EIRP – 6dB 4 Max EIRP – 8dB 5 Max EIRP – 10dB 6 Max EIRP – 12dB 7 Max EIRP – 14dB 8 Max EIRP – 16dB 9 Max EIRP – 18dB 10 Max EIRP – 20dB 11..14 RFU 15 Defined in [TS001] 31 Table 81: IN865-867 TXPower 1631 EIRP refers to the Equivalent Isotropically Radiated Power, which is the radiated output power 1632 referenced to an isotropic antenna radiating power equally in all directions and whose gain is 1633 expressed in dBi. 1634 By default, Max EIRP is considered to be 30 dBm. If the end-device cannot achieve 30 dBm 1635 EIRP, the Max EIRP SHOULD be communicated to the Network Server using an out-of-band 1636 channel during the end-device commissioning process. 1637 2.12.4 IN865-867 Join-Accept CFList 1638 The India 865-867 band LoRaWAN implements an OPTIONAL CFList of 16 octets in the Join- 1639 Accept message for both CFListType 0 and CFListType 1. When receiving a CFListType 1640 1, it shall be interpreted according to the channel list definition in Section 2.3.2.1 (800 MHz 1641 Fixed Channel List Definition). 1642
