Abstract

The problem of being able to use in a practical way a single communication and remote control device, instead of requiring the use of multiple communication and multiple remote control devices for communication and automobile door opener and or ignition starters, is solved by this invention. A wireless signal is transmitted by cellular transmission, received and processed in an automobile for control of a door lock or control of ignition. Processed location finder, touch screen, time division multiple access (TDMA), Code Division Multiple Access (CDMA), orthogonal frequency division multiplex (OFDM) signals are provided for wireless transmission. Location finder Global Positioning System (GPS) signal and non GPS signals are received and processed. In addition to cellular system components, wireless local area networks (WLAN) and/or other wideband/broadband network devices, such as orthogonal frequency division multiplex (OFDM) transmitters and receivers are incorporated into the cellular devices. Radio Frequency Identification (RFID) devices are used in conjunction with Multiple Input Multiple Output (MIMO) communications systems. Signal transmitters include cross-correlated in-phase and quadrature phase quadrature modulated signals and also non-quadrature polar modulated signal transmitters and diversity transceivers.
