A METHOD AND SYSTEM FOR FREE-SPACE COMMUNICATION

摘要

A method, device, and system for communicating data modulated on an electromagnetic signal over free space in the atmosphere includes a Far Infrared (FIR) transciever (104) having a trasmitter and a receiver. The tranmitter includes a laser source configured to generate an electromagnetic signal in the FIR range and a modulator for modulating the electromagnetic signal giving rise to modulated data. The modulated data is transmitted at high transmission rates through free space. The receiver includes a detector for receiving modulated data at the high transmission rates through free space. A Near Infrared (NIR) transceiver (105) communicates data modulated on an electromagnetic signal in the NIR over free space in the atmosphere.
