Abstract
A telecommunications network for linking a plurality of premises, comprising, typically, a fiber optic or coaxial cable, and a plurality of electrical power cables each connected to a respective one of the premises for supplying mains electrical power thereto. Each of the power cables is also connected to the fiber optic or coaxial cable so that telecommunications signals are transmissible between the fiber optic or coaxial cable and each of the power cables. A telecommunications signal is transmissible to the plurality of premises by being transmitted along the fiber optic or coaxial cable and subsequently along the respective power cable of each of the premises.
Claims19
A network linking a plurality of premises, comprising:
- a section of broadband telecommunications network, and
- a plurality of electrical power cables each connected to a respective one of the premises for supplying mains electrical power thereto, and each being entirely external to said plurality of premises,
- each of said power cables also being connected to the section of broadband telecommunications network so that telecommunications signals are transmissible between the section of broadband telecommunications network and each of said power cables,
- wherein a telecommunications signal is transmissible at a carrier frequency greater than 1 MHz to and/or from said plurality of premises by being transmitted along the section of broadband telecommunications network and also along the respective power cable of each of said premises.

A network linking a plurality of premises, comprising:
- a section of broadband telecommunications network,
- a plurality of electrical power cables each connected to a respective one of the premises for supplying mains electrical power thereto, and each being entirely external to said plurality of premises, and
- a plurality of interface units, each of said interface units connecting one of said power cables to said section of broadband telecommunications network, each of said interface units including a high pass filter for allowing high frequency telecommunications signals to pass between said section of broadband telecommunications network and said power cable, and for preventing low frequency mains electrical power signals from passing therebetween,
- wherein a telecommunications signal is transmissible at a carrier frequency greater than 1 MHz to and/or from said plurality of premises by being transmitted along the section of broadband telecommunications network and also along the respective power cable of each of said premises, and
- further including a satellite receiver for receiving telecommunications signals from a satellite transmitter, wherein a telecommunications signal is transmissible from said satellite transmitter to said plurality of premises via said satellite receiver, said section of broadband telecommunications network and said power cables,
- wherein said section of broadband telecommunications network includes any or all of fiber optic, twisted pair or co-axial cable.
3 more elements
A method of transmitting a telecommunications signal between a pair of buildings, including the steps of:
- (i) transmitting the signal at a carrier frequency greater than 1 MHz from a first building along an external power cable for supplying mains power to the first building, followed by
- (ii) transmitting the signal along a section of broadband telecommunications network, followed by
- (iii) transmitting the signal along a second external power cable for supplying mains electrical power to the second building.
A method of transmitting a telecommunications signal to respective telecommunications apparatus in each of a plurality of buildings, including the steps of:
- (i) transmitting the telecommunications signal over a broadband telecommunications line paralleling an electrical power distribution line external to said buildings, said electrical power distribution line supplying power to each of said buildings via a respective power cable, said respective power cable being connected to said electrical distribution line at a branch point external to said each of said buildings;
- (ii) near the respective branch point connecting said respective power cable to said electrical power distribution line and at a location external to said each of said buildings, injecting said telecommunications signal from said broadband telecommunications line onto said respective power cable for conveying said telecommunications signal over said respective power cable to said each of said buildings;
- and
- (iii) near or in said each of said buildings, conveying said telecommunications signal from said respective power cable to said telecommunications apparatus in said each of said buildings.
1 more element
A method of transmitting a telecommunications signal to respective telecommunications apparatus in each of a plurality of buildings, including the steps of:
- (i) transmitting the telecommunications signal over a broadband telecommunications line, there being an electrical power distribution line external to said buildings, said electrical power distribution line supplying power to each of said buildings via a respective power cable, said respective power cable being connected to said electrical distribution line at a branch point external to said each of said buildings;
- (ii) near the respective branch point connecting said respective power cable to said electrical power distribution line and at a location external to said each of said buildings, injecting said telecommunications signal from said broadband telecommunications line onto said respective power cable for conveying said telecommunications signal over said respective power cable to said each of said buildings;
- and
- (iii) near or in said each of said buildings, conveying said telecommunications signal from said respective power cable to said telecommunications apparatus in said each of said buildings.
1 more element
A network linking a plurality of buildings, comprising:
- a section of broadband telecommunications network, and
- an electrical power distribution line external to said buildings, said electrical power distribution line supplying power to each of said buildings via a respective power cable, said respective power cable being connected to said electrical distribution line at a branch point external to said each of said buildings;
- near the respective branch point connecting said respective power cable to said electrical power distribution line and at a location external to said each of said buildings, each of said power cable also being connected to the section of broadband telecommunications network so that it is possible to inject said telecommunications signal from said broadband telecommunications line onto said respective power cable for conveying said telecommunications signal over said respective power cable to said each of said buildings and for conveying said telecommunications signal from said respective power cable to said telecommunications apparatus in said each of said buildings.
