RF Characteristics
The RAK
3272
S module supports the LoRaWAN bands listed in the table below. When purchasing a RAK
3272
S module, ensure you specify the
correct core module,
RAK
3372
PL
or
RAK
3372
, based on your region. The
L
su
ffi
x indicates compatibility with low-frequency regions, while
modules without a su
ffi
x (
RAK
3172
P
) are designed for high-frequency regions.
