A position enhanced cellular telephone system wherein a cellular telephone device incorporates an RF position finder facility, a data modem and controller and a car alarm device, having a system for flexibly merging the functionality of the telephone device, position finder facility, data modem, controller, and car alarm, reduce overall components and lower the cost. A microprocessor, with a memory, is provided with a plurality of data input and output terminals. Car alarm and position signals from said RF position finder facility to an input terminal on the microprocessor. A signal conversion circuit converts RF to baseband and vice versa, and electronic switch device controlled by the microprocessor for coupling RF signals to and from the cellular telephone device to the signal conversion circuit. A digital signal processor (DSP) coupled to said microprocessor and controlled thereby, said DSP being adapted to a microphone and a speaker connected to the DSP, and the DSP is coupled to the signal conversion circuit.
In a position enhanced cellular telephone system wherein a cellular telephone device incorporates a position finder facility, a data modem and controller and a car alarm device, the improvement for merging the functionality of said cellular telephone device, position finder facility, data modem, controller, and car alarm, the improvement comprising a function integrating unit, including:
