doc.: IEEE 802. 15-15-0080-00-007r1 Optical Wireless Communication (OWC) • Optical Wireless Communication (OWC) is the technology that uses wireless communication via visible or non-visible light to exchange voice/video/data from one optical source (or device) to one or more devices ( or sources). • Peer-to-peer, stat, broadcast topology • OWC gains advantages such as low power consumption, low voltage, no interference with RF, high speed read and write capability, high security, harmlessness to human health, green environment, and etc. Modulated Information Intensity Modulation (IM) Direct Detection (DD) Yeong Min Jang, Kookmin University
IEEE 802.15.7 vs. IEEE 802.15.7r1 • IEEE 802.15.7r1 consider camera and/or image sensor as receiver along with photo diode. • The spectrum considered in IEEE 802.15.7r1 is 10,000nm (IR to near UV region) compared to 400nm VLC spectrum considered in IEEE 802.15.7. • There is basic difference in receiving technique between photo diode and camera • Existing standard doesn’t consider some special issue related to camera • Need to consider following issues • Flickering • Dimming • Synchronization • Exposure time and Variation in camera frame-rate • Low camera frame-rate Yeong Min Jang, Kookmin University
