Abstract

A wireless communications link, including a base unit and at least one remote unit. The base unit is connected to a wired communications line, so as to receive electrical signals from the line and transmit diffuse infrared radiation, modulated responsive to the received electrical signals, and to receive modulated infrared radiation and transmit electrical signals over the communications line responsive to the received infrared radiation. The at least one remote unit is connected to an audiovisual device, and couples the device to the communications line by receiving the modulated infrared radiation transmitted by the base unit and transmitting modulated diffuse infrared radiation to the base unit.

Claims

1. A wireless communications link between a telephone line connector and at least one audio-visual device, said communications link comprising:

a telephone line side unit including;

a telephone line side connector for engagement with said telephone line connector for bidirectional audio-visual data communication, providing communication between a telephone line and at least one audio-visual device;

a telephone line side infrared transmitter which transmits diffuse infrared radiation corresponding to said signal communication; and

a telephone line side infrared receiver which receives diffuse infrared radiation corresponding to said signal communication; and

an audio-visual device side unit including;

an audio-visual device side connector for engagement with said audio-visual device for bidirectional signal communication therewith via a modem;

an audio-visual device side infrared transmitter which transmits diffuse infrared radiation to said telephone line side infrared transmitter; and

an audio-visual device side infrared receiver which receives diffuse infrared radiation from said telephone line side infrared transmitter.

2. A wireless communications link according to claim 1 and wherein said audio-visual device comprises a television.

3. A wireless communications link according to claim 2 and wherein said signal communication comprises internet television communication.

4. A wireless communications link according to claim 1 and wherein said telephone line side unit also comprises a unitary housing enclosing said a telephone line side connector, said telephone line side infrared transmitter and said telephone line side infrared receiver.

5. A wireless communications link according to claim 1 and wherein said audio-visual device side unit also comprises a unitary housing enclosing said audio-visual device side connector, said audio-visual device side infrared transmitter, and said audio-visual device side infrared receiver.

6. A wireless communication link according to claim 1 and wherein said audio-visual device comprises a computer.

7. A wireless communications link according to claim 1 and wherein said audio-visual device side unit is incorporated in said audio-visual device.

8. A wireless communications link according to claim 1 and wherein said audio-visual device side unit is external to said audio-visual device.

9. A wireless communications link according to claim 1 and wherein said signal communication is full-duplex communication.
