MULTIPLE MODE WIRELESS DATA LINK DESIGN FOR ROBUST ENERGY EFFICIENT OPERATION

摘要

The invention provides power smart in-door optical wireless link that provides lossless beam propagation between Transmitter (T) and Receiver (R) for changing link distances including in conditions of transmit and receive beam spoiling due to environmental effects. Each T/R unit uses a combination of fixed and variable focal length optics (called inverse adaptive optics) to smartly adjust the transmit beam laser beam propagation parameters of minimum beam waist size and its location to produce the optimal zero propagation loss coupling condition at the Receiver for the specific link distance.
