Abstract
A wireless modem is provided with a passive power source using a first PCMCIA slot that is normally provided in mobile computer systems. Most mobile computing systems today provide for two or more PCMCIA slots. In the preferred embodiment of the present invention one slot is used by a first PCMCIA adapter that provides for baseband signal processing and power signals to a transceiver device. A second PCMCIA adapter card supplements the power signals provided by the first PCMCIA adapter card to the transceiver. The second PCMCIA adapter card occupies a second PCMCIA slot. The second PCMCIA adapter card supplements the power signals provided by the first PCMCIA card, permitting the transceiver to draw more current than that available from the first PCMCIA card. The transceiver and PCMCIA cards are interconnected by a Y cable in the preferred embodiment and a three connector housing in an alternative embodiment.
