Abstract
An infrared transceiver for an application interface card for use with a computer in a wireless Local Area Network. The transceiver includes a multi-facet beam deflector to maximize dispersion of the infrared beams in a room while maintaining a compact arrangement for the interface card. In another aspect, the transceiver includes a revolving turret to provide directional capabilities for serial IR or point-to-point communication applications. The transceiver is suitable for PCMCIA interface cards.
Claims4
An application interface card for providing a wireless communication interface for a computer, said interface card comprising:
- a card housing;
- a plurality of light emitting diodes and photodiodes located on an extension portion of said card housing;
- a circuit for operating said light emitting diodes and said photodiodes, said circuit including an interface for receiving signals from said computer;
- a reflector positioned at the emitting end of said light emitting diodes for deflecting beams emitted by said light emitting diodes in controlled directions to produce a predetermined beam dispersal pattern wherein said reflector comprises a plurality of angled surfaces, said angled surfaces being arranged to deflect beams emitted by said light emitting diodes in predetermined directions.
