Proposed Band Plan preamble group 1 preamble group 2 preamble group 3 preamble group 4 Narrower band separation (Bands N= 1 to 20) : 499.2 MHz Narrower band centre frequencies: N*499.2 Wider band separation (Bands N = 21 to 27) : 1331.2 MHz Narrower band centre frequencies: 1331.2 * (N-20) MHz

Band Centre Frequencies Mandatory to have either Band 1, Band 9 or Band 16.
