Abstract(in English) | The spotlight is on Visible-Light Wireless Communication System using White LED. These days, pervasive computing is increasing attention and the Visible-Light Communication technology matches exactly. We use wireless network everywhere as mobile phone and light is all over the place. We could say visible light was the blinded spot of wireless communication. LED has more advantageous than the incandescent light in terms of longer lifetime, lower power consumption, and faster response. Therefore, LED light can be used not only as a general light but also in high-speed wireless communication system. A conventional numerical analysis has problems when we calculate the maximum transmission speed. One problem is conventional numerical analysis show transmission speed as infinite when receiver's Field of View is infinitesimal. Other problem is that conventional analysis does not take discomfort glare of light into consideration. In order to calculate the maximum transmission speed, numerical analysis should be more realistic. The author will propose a numerical analysis and a simulation to calculate the maximum transmission speed. First proposal is that a point source LED should be assumed as surface light source to improve conventional numerical analysis. Second proposal is Ray-Tracing photon simulation using examples from liquid-crystal-display simulation. From these two proposals we can calculate more realistic transmission speed limit. From simulation, in general office model, the maximum transmission speed limit is about ITbps. Hence, we could say that Visible-Light Wireless Communication System using White LED is not only novelty technology using lightings, but also a high-speed wireless technology for pervasive computing. |
