The data 1568 rate is a function of the uplink data rate and the RX1DROffset, as given by the following 1569 table. The allowed values for RX1DROffset are in the [0:5] range. Values in the [6:7] range 1570 are reserved for future use. 1571 1572 Upstream Data Rate Downstream Data rate RX1DROffset 0 1 2 3 4 5 DR0 DR0 DR0 DR0 DR0 DR0 DR0 DR1 DR1 DR0 DR0 DR0 DR0 DR0 DR2 DR2 DR1 DR0 DR0 DR0 DR0 DR3 DR3 DR2 DR1 DR0 DR0 DR0 DR4 DR4 DR3 DR2 DR1 DR0 DR0 DR5 DR5 DR4 DR3 DR2 DR1 DR0 Table 75: KR920-923 downlink RX1 data rate mapping 1573 The RX2 receive window uses a fixed frequency and data rate. The default parameters are 1574 921.90 MHz / DR0 (SF12, 125 kHz). 1575 2.11.8 KR920-923 Class B Beacon and Default Downlink Channel 1576 The beacon frame content is defined in section 4.1.3. 17 1577 The default beacon data rate is DR3. 1578 The default beacon broadcast frequency is 923.1 MHz. 1579 The default class B downlink ping-slot frequency is 923.1 MHz 1580 2.11.9 KR920-923 Relay Parameters 1581 The WOR default channels are: 1582 Channel Index 0 1 Frequency WOR (MHz) 922.7 923.1 Frequency WOR ACK (MHz) 922.9 923.1 SF SF9 BW BW125 Table 76: KR920-923 WOR default channel 1583 2.11.10 KR920-923 Default Settings 1584 There are no specific default settings for the KR920-923 MHz band. 1585 2.12 IN865-867 MHz Band 1586 2.12.1 IN865-867 Preamble Format 1587 Refer to Section 4, "Physical Layer". 1588 2.12.2 IN865-867 Band Channel Frequencies 1589 This section applies to the Indian sub-continent. 1590 The network channels can be freely attributed by the network operator. However, the three 1591 following default channels SHALL be implemented in every India 865-867 MHz end-device. 1592 Network gateways SHALL be listening on one or more of these channels. 1593
