966 == 13.2  The node is very close to the gateway, but the signal is poor ==
967
968
969 If you are using US915 or AU915, you found the frequency points of different subband ranges in your uplink
970
971 Like that：Both 905.1Mhz and 902.3Mhz appear on uplink
972 But they belong to Subband1 and Subband2 of US915 respectively
973
974 Cause: The server and the gateway use different frequency bands (the server uses Subband1, and the gateway uses Subband2)
975
976 In server side, it shows the frequency is 905.1Mhz, which is sub-band2. But the RSSI is very low, Because this is not a signal in 905.1Mhz, it is on 902.3Mhz, the signal is too strong and appear a noise in 905.1Mhz.
977
978 How to check the frequency band used by the server：
979
980 You can view the information sent by the server: ch_mask in Unconfirmdedatadown
981
982 [[image:image-20230821113255-1.png]]
983
984 According to lorawan's protocol, your first ch_mask is 7 for ChMaskCntl = 7 then 125 kHz channels are disabled. Simultaneously the channels 64 to 71 are set according to the ChMask bit mask.
985
986 [[image:image-20230821113539-2.png]]
987
988 In the second message, the channel 0~~7 is true, which means that your server is using subband2.
