1. An advanced cellular telephone for facilitating voice and data communication over a plurality of wireless communication networks, at least one of which is a Personal Communication Services network operating in the PCS frequency band using a protocol for communication that is appropriate for the PCS network and at least one additional network operating either inside or outside of the PCS frequency band using a protocol for communication that is appropriate for the one additional network, comprisinga housing small enough to form a portable handset;

  • an antenna supported by the housing for transmitting and receiving electromagnetic energy;

    a display, supported by the housing, for displaying information that is visually perceptible to a user and that includes information procured, in response to a user request, from a remote computer with which the cellular telephone is linked wirelessly via one of the wireless communication networks;

    a touch-sensitive device for receiving user supplied commands and data including said user requests for information; and

    an omni-modal communication circuit for accessing the wireless communication networks using a communications protocol appropriate to the wireless communication network accessed to establish a communication link for voice or data communication over the accessed network, the omni-modal communication circuit includinga transceiver, electrically connected to the antenna, for sending and receiving radio frequency voice signals and data signals,digital modulator circuitry for modulating digital voice signals and digital data signals onto a carrier for transmitting by the transceiver in accordance with a communications protocol compatible with the PCS communication network when accessed and in accordance with a communications protocol compatible with the one additional network when accessed,digital demodulator circuitry for demodulating digital voice signals and digital data signals from radio frequency signals received by the transmitter in accordance with the communications protocol compatible with the PCS communication network when accessed and in accordance with the communications protocol compatible with the one additional network when accessed,memory for storing an operating program and data including network information, telephone numbers and text messages, anda processor for setting up appropriate cross connections between the display, memory, touch-sensitive device, digital modulator circuitry and digital demodulator circuitry and transceiver to cause the transceiver to access the plurality of wireless communication networks, one or more at a time, including the PCS network and the one additional network, for sending and receiving both voice signals and data signals over the accessed network and to receive user commands, to provide information to the display, to carry out arithmetic calculations, to request information from remote computers and to retrieve data from memory;

    wherein the functions of information retrieval from remote computers, data processing and placing or receiving telephone calls may be carried out by selective access, under the control of the processor, to the plurality of wireless communication networks including the PCS network and the one additional network through operation of the omni-modal communication circuit.
