Abstract

A telecommunication system including a master unit operative to receive/transmit data from at least one base transceiver station, at least one telecommunication antenna operative to receive/transmit the data wirelessly to and from wireless communication devices, a remote unit connecting the master unit to the telecommunications antenna and including a ground-hardened outer casing and a digital or packet energy transfer (PET) power distribution system is integrated with the operative to transfer packets of digital energy from a transmitter to a PET receiver, the PET receiver powering the remote unit and disposed internally of the ground-hardened outer casing thereof.

First claim

The following is claimed:

1 . A telecommunication system comprising:
a master unit configured to exchange data with a cellular station; a telecommunication antenna configured to exchange data wirelessly with a wireless communication device; a remote unit connecting the master unit to the telecommunications antenna and exchanging data therebetween; and a packet energy transfer transmitter configured to transmit packets of electrical power along a conductive cable; and a packet energy transfer receiver configured to receive and convert the packets of electrical power into a continuous source of power for the remote unit.

2 . The telecommunication system of claim 1 wherein the remote unit comprises a conductive outer casing, and wherein the packet energy transfer receiver is enclosed within and electrically shielded by the conductive outer casing.

3 . The telecommunication system of claim 2 further comprising:
a hybrid cable connecting the master unit and the packet energy transfer receiver to the remote unit, the hybrid cable comprising a optic fiber for exchanging data and a conductive cable for transmitting power to the packet energy transfer receiver.

4 . The telecommunication system of claim 1 further comprising an optic fiber cable configured to exchange data between the master unit and a plurality of remote units, and further comprising a wave division multiplexer configured to send multiple signals through the optic fiber cable to each of the remote units.

5 . The telecommunication system of claim 1 wherein the packet energy transfer receiver produces a continuous source of analog power having a first potential; and further comprising:
a converter configured to receive the source of analog power and reduce the analog power from the first to a second potential, the second potential being lower than a threshold potential.

6 . The telecommunication system of claim 5 wherein the threshold potential is a safety threshold regulated by a governing authority.

7 . The telecommunication system of claim 5 wherein the first potential is higher than the second potential by at least an order of magnitude.

8 . The telecommunication system of claim 5 wherein the converter includes an interface port comprising a multi-pin connector.

9 . The telecommunication system of claim 7 wherein the conductive cable is configured to carry a first current on a first side of an interface port and a second current on a second side of the interface port, the first current being larger than the second current.

10 . The telecommunication system of claim 5 wherein the remote unit includes a conductive outer casing, and wherein the converter is enclosed within and electrically shielded by the conductive outer casing.

11 . The telecommunication system of claim 5 wherein the converter is a DC-to-DC converter.

12 . The telecommunication system of claim 5 wherein the converter is a DC-to-AC inverter.

13 . The telecommunication system of claim 5 wherein the second potential less than about sixty volts.

14 . The telecommunication system of claim 2 further comprising an interface port integrated with the outer casing, the interface port having a plurality of interface elements, the interface elements comprising one of an optical connection and a conductive pin connection.

15 . A power-data distribution system for a DAS telecommunication system comprising:
a power distribution system having a packet energy transfer transmitter and a packet energy transfer receiver, a remote radio unit: (i) electrically powered by the packet energy transfer receiver, (ii) optically and electrically coupled to a cellular radio, and (iii) electrically coupled to a plurality of telecommunication antennas, the telecommunication antennas wirelessly exchanging data with a plurality of cellular communication devices; a wireless fidelity access point device having an internal antenna operative to exchange internet data with a WAP-enabled device; and a fiber media converter: (i) optically and electrically coupled to the packet energy transfer receiver, and (ii) electrically coupled to the WAP-enabled device.

16 . The power-data distribution system of claim 15 further comprising a Power over Ethernet cable interposing the fiber media converter and the WAP-enabled device and wherein electrical power and internet data are carried over a wire cable of the Power over Ethernet cable.

17 . The power-data distribution system of claim 16 further, comprising:
a hybrid cable interposing the packet energy transfer transmitter and the packet energy transfer receiver and configured to optically and electrically connect the fiber media converter to the cellular radio.

18 . The power-data distribution system of claim 16 wherein the remote unit comprises a conductive outer casing, and wherein the packet energy transfer receiver is enclosed within and electrically shielded by the conductive outer casing.

19 . The power-data distribution system of claim 16 wherein the packet energy transfer receiver produces a continuous source of analog power having a first potential; and further comprising:
a converter configured to receive the source of analog power and reduce the analog power from the first to a second potential, the second potential being lower than a threshold potential.

20 . The power-data distribution system of claim 19 wherein the threshold potential is a safety threshold regulated by a governing authority.
