Abstract:
Methods of operating a cellular radio are provided in which a first power supply signal is transmitted from a power supply to a wireless power unit at least in part over a power cable. A second power supply signal is wirelessly transmitted from the wireless power unit to the cellular radio to power the cellular radio. Data is transmitted from a baseband unit that is associated with the cellular radio to a wireless transceiver at least in part over a data cable. This data is wirelessly transmitted from the wireless transceiver to the cellular radio. The data is then transmitted through an antenna that is coupled to the cellular radio.

Abstract:
Tower systems suitable for use at cellular base stations include a tower, an antenna mounted on the tower, a remote radio head mounted on the tower and a power supply. A power cable having a power supply conductor and a return conductor is connected between the power supply and the remote radio head. A shunt capacitance unit that is separate from the remote radio head that is electrically coupled between the power supply conductor and the return conductor of the power cable.
Abstract:
Certain aspects are directed to an interceptor system for characterizing digital data communicated between certain points in a telecommunication system. The interceptor system includes an interface device and a processing device. The interface device can retrieve data from at least one communication link between a radio frequency processing unit and a baseband processing unit of a telecommunication system. The data includes digital data communicated between the radio frequency processing unit and the baseband processing unit. The processing device can determine an interface link protocol for communicating with terminal equipment via the telecommunication system. The interface link protocol can be determined based on an organization of the data retrieved from the communication link.
