Title:
OPTICAL WIRELESS COMMUNICATION SYSTEM WITH MULTIPLE RECEIVERS
Document Type and Number:
WIPO Patent Application WO2002086556
Kind Code:
A3
Abstract:
A cellular optical wireless network (10) includes multiple bi-directional point-to-point links between a central hub (12) and dispersed clients (14). When the hub (14) is limited in wize, the receivers may be in close proximity to one another. In this case, the optical signal from two or more clients, which may have spread significantly in diameter due to angular spread in the transmitted light, may overlap spatially at the hub, causing interference and difficulty in separating the data. The present invention provides techniques to avoid such interference.
