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.

Claims

1. A trunk cable assembly for a cellular base station, comprising:

a trunk cable that includes a conductive power cable and a fiber optic data cable;

a trunk cable termination that is directly attached to the trunk cable, the trunk cable termination including;

an enclosure;

a wireless power unit that is electrically connected to the conductive power cable;

an optical-to-electrical converter that is coupled to an optical fiber of the fiber optic data cable; and

a wireless transceiver that is coupled to an output of the optical-to-electrical converter,

wherein the wireless power unit, the optical-to-electrical converter and the wireless transceiver are at least partly within the enclosure.

2. The trunk cable assembly of claim 1, wherein a common jacket encloses the conductive power cable and the fiber optic data cable to provide a hybrid fiber optic-power trunk cable, and wherein the enclosure is a permanently-sealed enclosure.

3. The trunk cable assembly of claim 2, wherein the wireless power unit is configured to wirelessly transmit power to a tower-mounted radio of the cellular base station and the wireless transceiver is configured to wirelessly transmit data to the tower-mounted radio of the cellular base station.
