However, the two following default 1958 channels SHALL be implemented in every RU864-870 MHz end-device. Network gateways 1959 SHALL be listening on one or more of these channels. 1960 1961 Modulation Bandwidth [kHz] Channel Frequency [MHz] LoRa DR / Bitrate Number of Channels Duty Cycle LoRa 125 868.9 869.1 DR0 to DR5 / 0.3-5 kbps 2 <1% Table 100: RU864-870 default channels 1962 RU864-870 MHz end-devices SHALL be capable of operating in the 864 to 870 MHz 1963 frequency band and SHALL feature a channel data structure to store the parameters of at 1964 least 24 channels. A channel data structure corresponds to a frequency and a set of data rates 1965 usable on this frequency. 1966 The first two channels correspond to 868.9 and 869.1 MHz / DR0 to DR5 and SHALL be 1967 implemented in every end-device. For devices compliant with [TS001-1.0.x], those default 1968 channels SHALL NOT be modified through the NewChannelReq command. For devices 1969 compliant with [TS001-1.1.x] and beyond, these channels MAY be modified through the 1970 NewChannelReq command but SHALL be reset during the back-off procedure defined in 1971 [TS001] to guarantee a minimal common channel set between end-devices and network 1972 gateways. 1973 The following table gives the list of frequencies that SHALL be used by end-devices to 1974 broadcast the Join-Request message. The Join-Request message transmit duty-cycle SHALL 1975 follow the rules described in chapter "Retransmissions back-off" of the LoRaWAN [TS001] 1976 specification document. 1977 Modulation Bandwidth [kHz] Channel Frequency [MHz] LoRa DR / Bitrate Number of Channels LoRa 125 868.9 869.1 DR0 – DR5 / 0.3-5 kbps 2 Table 101: RU864-870 Join-Request channel list 1978 1979
