Processing in a mobile device a motion detector generated signal into a motion detector generated control signal, for navigation control of mobile device. Remote Control (RC) Signal reception, demodulation and processing for control of automobile communication, location and navigation. Modulation and demodulation, transmission and reception of one Orthogonal Frequency Division Multiplexed (OFDM) signals and conversion of the received OFDM signal into a different OFDM signal. Received spread spectrum signals from 3G or 4G or 5G cellular systems and networks are converted into OFDM signals and transmitted in a wireless network, e.g. a Wi-Fi network. One or more receivers and demodulators for receiving demodulating and processing received signals into location finder information. A video camera in mobile device generates video signal and transmits video signal with location finder information signal.
