The Framework of the Integrated Power Line and Visible Light Communication Systems
Power line communication (PLC) draws significant attentions recently for its wide applications in the smart grid, Internet-of-Things, and intelligent homes. Visible light communication (VLC) using light emitting diode (LED) is becoming a hot topic due to its high capacity and radiation-free benefits, and meanwhile it can be naturally combined with PLC for the cost-effective implementation. In t...
متن کاملOptical Wireless Sensor Networks Based on VLC with PLC-Ethernet Interface
We present a white LED-based optical wireless communication systems for indoor ubiquitous sensor networks. Each sensor node could access to the server through the PLC (Power Line Communication)-Ethernet interface. The proposed system offers a full-duplex wireless link by using different wavelengths to reduce the inter-symbol interference between uplink and downlink. Through the 1-to-n optical w...
متن کاملDegree Programme in Electrical Engineering Design and Implementation of a Bi- Directional Visible Light Communication Testbed
This work defines a bi-directional visible light communication (VLC) testbed design and implementation process using Universal Software Radio Peripheral (USRP) software defined radios (SDR) and open-source software. The visible light communication design uses LED light sources for wireless communications purposes. The testbed combines light, infrared and radio frequencies as wireless media to b...
متن کاملVisible Light Communication
The visible light communication (VLC) refers to the communication technology which utilizes the visible light source as a signal transmitter, the air as a transmission medium, and the appropriate photodiode as a signal receiving component. The visible light communication technology has a short history compared with other communication technology, for example, public old telephone service, Ether...
متن کاملAdaptive Equalization System for Wireless Communication Using White LED
White LEDs were invented the 1990’s. The white LED has lower power consumption, lower voltage requirements, longer lifetime, smaller size, faster response, and cooler operation. We have proposed an indoor visible light wireless communication system that utilizes multiple white LED lighting equipment. In this system, the equipment is used not only for illuminating rooms but also for an optical w...
