ABSTRACT:
A cellular mobile base station apparatus comprises a first plurality of transceivers operating in a first radio frequency range assigned to a first cell and receiving power from a first power supply unit, a second plurality of transceivers operating in a second radio frequency range assigned to a second cell and receiving power from the first power supply unit, a third plurality of transceivers operating in the first radio frequency range and receiving power from a second power supply unit, and a fourth plurality of transceivers operating in the second radio frequency range and receiving power from the second power supply unit. The outputs of the first and third pluralities of transceivers are combined and transmitted from a first antenna and a signal in the first frequency range received by the first antenna is decomposed into first frequency range individual signals and applied to the first and third pluralities of transceivers. The outputs of the second and fourth pluralities of transceivers are combined and transmitted from a second antenna, and a signal in the second frequency range received by the second antenna is decomposed into second frequency range individual signals and applied to the second and fourth pluralities of transceivers.
