A ship based cellular and satellite transceiver receives, demodulates and processes data, voice and video signals from a satellite transmitter and provides the processed signals in cascade to a OFDM and to a CDMA modulator and transmitter for transmission to a ship based mobile unit. The OFDM signal is transmitted in a Wi-Fi network and the CDMA signal is transmitted in frequency bands used by cellular phones and cellular connected devices. The ship based transceiver receives from a mobile unit, e.g. from a cellular phone or a computer an OFDM or a CDMA signal generated and transmitted by the mobile unit and receives, demodulates and processes the cellular phone transmitted signal and provides these processed signals for cascade processing, modulation and transmission to a satellite.
