A cellular communication system having all of its components operating under a single system control unit is provided so that the various components of the system can be adjusted as the parameters of the other components or the dynamic characteristics of the cellular channel change. The cellular communication system includes: (a) a data pump for performing modem signal processing; (b) a cellular transceiver communicatively coupled to the data pump for performing cellular signaling protocols and signal conditioning; (c) a digital-to-analog (D/A) and analog-to-digital (A/D) converter communicatively coupled to the cellular transceiver; (d) a radio transceiver communicatively coupled to the D/A & A/D converter for transmitting and receiving control commands and radio waves; (e) a host interface for interfacing the data pump to a computer host; and (f) a single system control trait for controlling the host interface, the data pump, the cellular transceiver, the D/A & A/D converter, and the radio transceiver so that the host interface, the data pump, the cellular transceiver, the D/A & A/D converter, and the radio transceiver operate under a single operating system. The cellular communication system may also include a microphone, a speaker, and an encoder and a decoder (CODEC) unit. The cellular transceiver is designed so that it can select and process either data signals from the data pump or audio signals from the CODEC unit.
