911 +How to set up LSE01 to work in 8 channel mode By default, the frequency bands US915, AU915, CN470 work in 72 frequencies. Many gateways are 8 channel gateways, and in this case, the OTAA join time and uplink schedule is long and unpredictable while the end node is hopping in 72 frequencies.

927 927  For example, in **US915** band, the frequency table is as below. By default, the end node will use all channels (0~~71) for OTAA Join process. After the OTAA Join, the end node will use these all channels (0~~71) to send uplink packets.
