Information Illuminating System for Healthcare Institution
At some hospitals and nursing homes, people have already thought about improving healthcare quality, efficiency and accuracy by bring in the technology of Wireless Local Area Network (WLAN), which possesses the advantage of high mobility, flexibility and high speed. However, this idea always takes the risk that medical equipment may get disturbed by the invisible Electro Magnetic Interference (EMI). It has been proved by many cases that some precision medical instruments could not work properly when they are under radiofrequency radiation 1. In this paper we will describe a new wireless communication system with no RF radiation, no EMI but safety and convenience. This design takes the advantage of optical modulation based on hospital illuminating network. High brightness light-emitting diodes (HB-LED) are used in this system as illuminating source which take priority over conventional gas discharge fluorescent lamp or other low luminous efficient lamps. The information is modulated on the visible light emitted by HB-LED lighting source. A portable device is also designed to receive and demodulate the information, offering mobile data service.
