  • Patent number: 6778519
    Abstract: A computing environment in which a plurality of portable computers use a spread spectrum communications link to wirelessly communicate with and receive input from a plurality of peripheral devices. In a preferred embodiment, one or more portable or laptop computers each have a PCMCIA card. The PCMCIA card has an RF transreceiver that sends and receives spread spectrum signals, where each spread spectrum signal identifies and makes a demand upon a peripheral device. The spread spectrum signals from the transreceiver on each PCMCIA card are received by a transreceiver on a docking station that is interfaced to one or more peripheral devices. The docking station ‘de-spreads’ the spectrum signals and then directs the same to the particular interfaced peripheral device identified in the signal. A similar process is followed in transmitting a spread spectrum signal from one of the interfaced devices to a particular laptop computer.
