DR0 to DR5 (minimum set supported for certification) 1363 2. DR0 to DR7 1364 1365 For both options, all data rates in the range specified SHALL be implemented (meaning no 1366 intermediate data rate can be left unimplemented). 1367 When the device is using the Adaptive Data Rate mode and transmits using the DRcurrent 1368 data rate, the following table defines the next data rate (DRnext) the end-device SHALL use 1369 during data rate back-off: 1370 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 51: CN470-510 data rate back-off 1371 EIRP refers to the Effective Isotropic Radiated Power, which is the radiated output power 1372 referenced to an isotropic antenna radiating power equally in all directions and whose gain is 1373 expressed in dBi. 1374 By default, the Max EIRP is considered to be +19 dBm. If the end-device cannot achieve 19 1375 dBm EIRP, the Max EIRP SHOULD be communicated to the Network Server using an out-of- 1376 band channel during the end-device commissioning process. 1377 15 As of RP002-1.0.1, DR0 is unavailable for devices implementing CN470-510, but remains defined to better support existing implementations.
