Abstract
There will be adverse effects on human health while the exposure of Radio frequency (RF) waves is long term in the indoor environment. The old age people, children’s and patients will be badly affected, if their immune system is weak. In such environment, the visible light communication (VLC) is the preferred communication technique which provides immunity towards the adverse effects by RF. Presently the fluorescent lamps were replaced by light-emitting diodes (LEDs) in the indoor environment. The practice of utilizing the LEDs have been penetrated in many areas in our day to day life. The device will provide lightning capabilities and also information broadcast. In VLC for the purpose of data transmission and reception, the LED light source and photodetector (PD) were used. The work presents about VLC channel model, LED characteristics, data transmission model (RPO-OFDM-vDSM model) in indoors which provides better spectral efficiency and data rate.
