Wired and mobile wi-fi networks, cellular, GPS and other position finding systems

摘要

A voice signal is processed and connected by wire to a mobile wireless unit for further processing into time division multiple access (TDMA) and into spread spectrum signals. The wireless unit is processing a data signal into orthogonal frequency division multiplex (OFDM) signal. The wireless unit receives and processes a position finder signal from Global Positioning System (GPS) satellite and from land based transmitter and provides processed position finder signals. The wireless unit generates a processed touch screen control signal and processes the touch screen control signal with processed position finder, TDMA and spread spectrum signal or with processed OFDM signal and provides these processed signals to a transmitter for wireless signal transmission. The processed OFDM signal is used in a Wi-Fi wireless network and the TDMA or spectrum signal is used in a cellular system, wherein the wireless network and the cellular system are distinct. Processing of position finder signal incorporates step of receiving and processing a signal from Global Positioning System (GPS) satellite and from land based transmitter and for providing processed position finder signals received from GPS satellite and from land based transmitters for transmission. Processed TDMA or spread spectrum signals include code division multiple access (CDMA) and code selectable cross-correlated in-phase and quadrature-phase baseband signals. Modulation and amplification structures and methods of the hybrid wired and wireless systems include amplification by non-linearly amplified (NLA) and by linearly amplified transmitters.
