For a network to enable use of these data rates on existing channels, for example added using 1739 CFList, it is necessary to use a NewChannelReq MAC command to modify the DRRange 1740 using the values indicated in Table 81. To add an additional frequency using NewChannelReq 1741 the values of DRRange listed in this table are used. 1742 1743 Target Configuration DRRange Description of Example Configurations MaxDR MinDR DR0 to DR5 5 0 Minimum set supported for certification.

If the end-device cannot achieve 14 1757 dBm EIRP, the Max EIRP SHOULD be communicated to the Network Server using an out-of- 1758 band channel during the end-device commissioning process. 1759
