LoRaWAN® Regional Parameters RP002-1.0.4 ©2022 LoRa Alliance ® Page 83 of 101 The authors reserve the right to change specifications without notice. 2.13 RU864-870 MHz Band 1686 2.13.1 RU864-870 Preamble Format 1687 Refer to Section 4, "Physical Layer". 1688 2.13.2 RU864-870 Band Channel Frequencies 1689 The network channels can be freely attributed by the network operator in compliance with the 1690 allowed sub-bands defined by the Russian regulation. However, the two following default 1691 channels SHALL be implemented in every RU864-870 MHz end-device. Network gateways 1692 SHALL be listening on one or more of these channels. 1693 1694 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 87: RU864-870 default channels 1695 RU864-870 MHz end-devices SHALL be capable of operating in the 864 to 870 MHz 1696 frequency band and SHALL feature a channel data structure to store the parameters of at 1697 least 24 channels. A channel data structure corresponds to a frequency and a set of data rates 1698 usable on this frequency. 1699 The first two channels correspond to 868.9 and 869.1 MHz / DR0 to DR5 and SHALL be 1700 implemented in every end-device. For devices compliant with [TS001-1.0.x], those default 1701 channels SHALL NOT be modified through the NewChannelReq command. For devices 1702 compliant with [TS001-1.1.x] and beyond, these channels MAY be modified through the 1703 NewChannelReq command but SHALL be reset during the back-off procedure defined in 1704 [TS001] to guarantee a minimal common channel set between end-devices and network 1705 gateways. 1706 The following table gives the list of frequencies that SHALL be used by end-devices to 1707 broadcast the Join-Request message. The Join-Request message transmit duty-cycle SHALL 1708 follow the rules described in chapter "Retransmissions back-off" of the LoRaWAN [TS001] 1709 specification document. 1710 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 88: RU864-870 Join-Request channel list 1711 2.13.3 RU864-870 Data Rate and End-Device Output Power Encoding 1712 There is no dwell time limitation for the RU864-870 PHY layer. The TxParamSetupReq MAC 1713 command is not implemented in RU864-870 devices. 1714 The following encoding is used for Data Rate (DR) and end-device EIRP (TXPower) in the 1715 RU864-870 band: 1716 Data Rate Configuration Indicative Physical Bit Rate [bit/s] 0 LoRa: SF12 / 125 kHz 250 1 LoRa: SF11 / 125 kHz 440 2 LoRa: SF10 / 125 kHz 980 3 LoRa: SF9 / 125 kHz 1760
