Abstract
Recently there has been strong interest in wireless white LED (WLED) communication link applications in airplanes and avionics platforms for size, weight, cost, and electromagnetic interference (EMI) reduction. Wireless WLED link has additional advantage of providing network security because the optical signal from WLED link is well confined within an airplane or avionics vehicle. In this paper we discuss and analyze commercial-off-he-shelf WLED design and color measurement results. An experimental implementation of a low cost WLED transceiver which shows error free freespace operation at 10Mb/s is successfully demonstrated. The feasibly of implementing free space optical link which meets both lighting and communication requirements using WLED array is analyzed by mathematical modeling using MATLAB simulation technique.
