Abstract: Several million television receive antennas installed on roof tops in the US and around the world. A method is disclosed that uses each of the millions of television receive antennas as transmitters to provide high speed wireless mobile and broadband infrastructure to send and receive internet, data, audio, video, at user locations and communication between devices and sensors securely. This is the first converged broadcast and broadband interactive wireless infrastructure utilizing the television as an interface for applications such as financial transactions, home-to-home interconnection, environmental, energy management (smart meters), social networking, streaming, gaming, and security management. A personal server connects to a television receiver and antenna which connects among them wirelessly and connect to a broadcasting site server and an electric-substation server. The invention creates wireless cloud eliminating the need of a personal computer.

Abstract: Several hundred millions yagi antennas have been installed on roof tops around the world and more than 30 million in the UK. These yagi antennas are currently used to receive television only.

Abstract: A fibre optic data coupler comprises (a) a fibre optic data link input module comprising an input connector for a fibre optic connected to a fibre optic receiver for providing a digital electrical output signal corresponding to the fibre optic signal, (b) a coupler drive module for converting the digital electrical output signal to an analogue drive signal for input to an inductive coupler, (c) an inductive coupler unit comprising an inlet element for receiving the analogue drive signal and an outlet element for transmitting an induced analogue drive signal, corresponding to the input signal, (d) a coupler output module for converting the induced analogue drive signal to a digital electrical output signal for input to a fibre optic data link output module, and (e) a fibre optic data link output module comprising a fibre optic transmitter module, for providing a fibre optic signal corresponding to the digital electrical input signal, connected to a connector for a fibre optic.
