  • Patent number: 6400957
    Abstract: A wireless phone-line interface provides wireless communications between a modem and a switched telephone network. A wireless phone-line interface has a line interface transceiver coupled to a switched telephone network and a modem transceiver coupled to a modem. The modem may be coupled to computer, multimedia, or other electronic information equipment. The line interface transceiver and modem transceiver exchange wireless signals in reselected channels so that up-link and down-link frequencies transmitted and received by the line interface and modem transceivers are separate and distinct and do not interfere with one another. The cabling previously required between the modem and the switch telephone network is thereby eliminated, allowing easy relocation of the modem with its associated computer equipment to anywhere within the transmission range of the line interface and modem transceivers. The transceivers may be powered by DC-adapted 110 volt AC power.
