However, the three 1823 following default channels SHALL be implemented in every IN865 end-device. Network 1824 gateways SHALL be listening on one or more of these channels. 1825 1826 Modulation Bandwidth [kHz] Channel Frequency [MHz] LoRa DR / Bitrate Number of Channels Duty-Cycle LoRa 125 865.0625 865.4025 865.985 DR0 to DR5 / 0.3-5 kbps 3 Network Access Points (gateways): <= 10% Otherwise (devices): <= 2.5% Table 89: IN865 default channels 1827 End-devices SHALL be capable of operating in the 865 to 868 MHz frequency band and 1828 SHOULD feature a channel data structure to store the parameters of at least 24 channels. A 1829 channel data structure corresponds to a frequency and a set of data rates usable on this 1830 frequency. 1831 The first three channels correspond to 865.0625, 865.4025, and 865.985 MHz / DR0 to DR5 1832 and SHALL be implemented in every end-device. For devices compliant with [TS001-1.0.x], 1833 those default channels SHALL NOT be modified through the NewChannelReq command. For 1834 devices compliant with [TS001-1.1.x] and beyond, these channels MAY be modified through 1835 the NewChannelReq command but SHALL be reset during the back-off procedure defined in 1836 [TS001] to guarantee a minimal common channel set between end-devices and network 1837 gateways. 1838 The following table gives the list of frequencies that SHALL be used by end-devices to 1839 broadcast the Join-Request message. The Join-Request message transmit duty-cycle SHALL 1840 follow the rules described in chapter "Retransmissions back-off" of the LoRaWAN [TS001] 1841 specification document. 1842 1843 Modulation Bandwidth [kHz] Channel Frequency [MHz] LoRa DR / Bitrate Number of Channels LoRa 125 865.0625 865.4025 865.9850 DR0 – DR5 / 0.3-5 kbps 3 Table 90: IN865 Join-Request channel list 1844 1845
