satellite Modem manufacturers or suppliers
Modem is the shortform of modulator and demodulator. Modem is used basically in all the wireless and wireline systems. Main function of modem is to modulate baseband information on RF carrier and demodulare modulated rf signal to recover the baseband information. Modem used to access and to provide connectivity with satellite networks is called satellite modem. It connects one side with MUX/EPABX and the other side with RF Transceiver. It is mainly used to connect remote areas via satellite to provide voice/data application support.
