However the three 308 following default channels MUST be implemented in every EU868MHz end-device. Those 309 channels are the minimum set that all network gateways SHOULD always be listening on. 310 311 Modulation Bandwidth [kHz] Channel Frequency [MHz] FSK Bitrate or LoRa DR / Bitrate Nb Channels Duty cycle LoRa 125 868.10 868.30 868.50 DR0 to DR5 / 0.3-5 kbps 3 <1% Table 3: EU863-870 default channels 312 In order to access the physical medium the ETSI regulations impose some restrictions such 313 maximum time the transmitter can be on or the maximum time a transmitter can transmit per 314
