  • Data communication system using spectral overlay
    Patent number: 5548805
    Abstract: A data communication system is provided for use with a cellular system containing an array of cells and a cellular transmitter/receiver located within each cell of the array. Each cellular transmitter/receiver is adapted for transmitting and receiving voice and/or data communication over predetermined channelized frequencies associated with the particular cell in which the cellular transmitter/receiver is located. In accordance with the invention a base data transmission station is located in each cell and is adapted for transmitting a single data stream across a plurality of channels, each of which channels is adapted to carry a single stream of information. Each base data transmitting station does not transmit on the predetermined channels that are assigned to the particular cell in which the base data transmitting station is located (i.e., those channels are "notched").
