DR0 to DR5 (minimum set supported for certification) 1719 2. DR0 to DR7 1720 For both options, all data rates in the range specified SHALL be implemented (meaning no 1721 intermediate DR may be left unimplemented). 1722 When the device is using the Adaptive Data Rate mode and transmits using the DRcurrent 1723 data rate, the following table defines the next data rate (DRnext) the end-device SHALL use 1724 during data rate back-off: 1725 DRcurrent DRnext Comment 0 NA Already the lowest data rate 1 0 2 1 3 2 4 3 5 4 6 5 7 6 Table 90: RU864-870 data rate back-off 1726 EIRP 35 refers to the Equivalent Isotropically Radiated Power, which is the radiated output 1727 power referenced to an isotropic antenna radiating power equally in all directions and whose 1728 gain is expressed in dBi. 1729 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..14 RFU 15 Defined in [TS001] 31 Table 91: RU864-870 TXPower 1730 1731 By default, the Max EIRP is considered to be +16 dBm. If the end-device cannot achieve +16 1732 dBm EIRP, the Max EIRP SHOULD be communicated to the Network Server using an out-of- 1733 band channel during the end-device commissioning process. 1734 35 ERP = EIRP – 2.15dB; it is referenced to a half-wave dipole antenna whose gain is expressed in dBd.
