Assume we intend to use AS923, the two mandatory frequencies are 923.2 and 923.4. Other than these two, we are free to use any other frequencies right?
In TTN, for AS923, two frequency ranges are defined, AS1 and AS2. However, for private network, are we free to use any other frequencies as long as it is within the AS923 frequency band? (920 to 925 MHz) ?
You’re right with mandatory frequencies. According to Lorawan Regional Parameters Document, 923.2 and 924.4 are mandatory.
But what I’m not so sure is with the free ones.
According to the document this ISM band is for frequencies between 923 and 923.5.
