IF3-6 LoRa Channels
Multi-data rates
Radio B 867.1 - 867.1 MHz Radio A 866.6 -
867.4 MHz
IF7-10 LoRa Channels
Multi-data rates
IF1 500kHz fixed data rate
LoRa back-haul superposed
with sensor channels
The following IF frequencies are used:
Note : As shown in this example the 500 or 250 kHz
IF1 LoRa channel may overlap with the multidata
rate IF3 to 10 channels. Transmissions happening in
the IF7 to 10 channels will be noise like for the IF1
LoRa demodulator and reciprocally. It is however
better from a performance point of view to separate
as much as

possible different channels mainly when the
associated signal powers are very different (like
between a backhaul link which usually enjoys
line-of-sight attenuation and sensor link with
very low signal levels).
