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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
