The invention relates to a method for controlling output power of a radio
transmitter, the radio transmitter operating on a radio channel. The
method includes determining requested output power level, and deriving
output power, which is to be used, on the basis of a power control
algorithm having at least a first and a second power control area,
maximum output power of the first area being derived at least on the
basis of theoretical minimum attenuation to adjacent receivers, and
maximum output power of the second area being derived at least on the
basis of actual minimum attenuation to adjacent receivers, wherein an
adjacent receiver is a receiver operating on an adjacent channel with
respect to the operating channel of said radio transmitter.
