AbstractA new optical wireless network based on white LED lights in home area is proposed. It is a duplex channel communication system utilizing signal emitters of white LED lights in the downlink and infrared devices in the uplink. Strategies for the system construction are given. Performance for users' mobile access of different kinds of optical concentrators is investigated. Indoor channel bandwidth is analyzed considering white LED light distribution, wall reflection, and receivers field of view(FOV). Various modulation methods are discussed. A demo point-to-point system for surfing the net is constructed using a new line code of4B6B which is developed to stabilize the optical output, and a peak data rate of1Mbps is achieved. This system is built into the lighting infrastructure, therefore decreasing the cost and offering a solution for wireless access in places which are sensitive to radio frequency like hospitals.
