APPARATUS AND METHOD FOR IMPROVED CONNECTIVITY IN WIRELESS OPTICAL COMMUNICATION SYSTEMS

摘要

The present invention provides an apparatus and a method for improved connectivity in wireless optical networks. Therefore at least two or more receiving units are used which receive an infrared signal and convert it to a digital signal. The digital signals represent data in the form of frames whereby each frame comprises at least a data field and a header field containing a preamble. A selector determines a measure related to the signal-to-noise ratio of the preamble and compares the measures in order to select the best suited signal for further processing.
