Definitions
- the individual utilization of a particular power amplifier is determined and communicated to the central unit, which can be a radio network controller, for example.
- the maximum output power permitted for the power amplifier is the maximum permitted total transmission power of the corresponding radio cell in which the amplifier is located located.
- the maximum permissible output power of each amplifier is generally determined in such a way that the amplifier is prevented from being overloaded or operating in a non-linear region of its characteristic curve and thereby causing distortions.
- the maximum permissible transmission power of the cell is set so that the emissions from neighboring radio cells are not impaired too much.
- the focus here is on interference limitation.
- the maximum permissible transmission power of the cell is therefore determined accordingly on the network side.
- PCmax is the maximum transmission power permitted in the radio cell, which was previously determined by the radio network controller RNC.
- more than two antennas, each with a power amplifier, can also be provided within the base station BS.
