Adjacent Channel Power Measurements for Korean PCS Band

Adjacent Channel Power Measurements for Korean PCS Band
Most Adjacent Channel Power standards specify the power in the adjacent channels relative to the power in the target center channel. The standards for the Korean PCS band are different in that the third adjacent channel is specified absolutely (that is, in dBm) rather than relatively (that is, as dB).
The specifications for the Korean PCS band are shown in the next table.
