Abstract

Wired and mobile cascaded communication systems and processors used in wired and wireless local area network (WLAN) and mobile systems with touch screen generated communication and control signal and position finding signals. Systems with distinct modulators for wired, WLAN and mobile systems operated in separate network and systems. The WLAN includes use of orthogonal frequency division multiplexed (OFDM) signal, the mobile communication system includes use of time division multiple access (TDMA) signal and Code Division Multiple Access (CDMA) signal. Cascaded communication system includes receiving, processing and transmitting a Bluetooth signal. Communication system and WLAN has non-linearly amplified amplifier and linearly amplified amplifier for signal amplification and transmission and non-quadrature modulator and a quadrature modulator. Quadrature modulator is used for modulation of TDMA or CDMA filtered cross-correlated in-phase and quadrature-phase baseband signals. Position finding with processor for processing and providing processed location finding signals received from multiple GPS satellites and processed location finding signals received from land based cellular transmitters.
