RETROMODULATION-BASED DATA COMMUNICATION

摘要

A data communication system comprising a transceiver unit (10) for retromodulated optical communication with at least one of a plurality of retormodulator units (50), the transceiver unit comprising at least one of a plurality of transceivers (16), the transceivers transmitting diffused radiant energy (18) at different angles covering a predetermined three-dimensional area, wherein each transceive is enabled to set up and execute communication with at least one retromodulator comprising multiple arrays of lenslets or spherically arranged lenslets is provided for achieving a wide angle of acceptance. Furthermore, a number of novel applications based on the data communication system are provided, including a remote wireless network connection for a portable computing device, a smart card fo remote wireless identification, remote data collection, and remote downloading of digital photographs.
