Attackers may not only easily monitor communication but also launch jamming (denial of service) attacks. The shared nature of the medium allows wireless networks to be easily monitored and broadcast on. Currently, the VLC industry seems to be on the same path again: the indubitable “pro-security” physical characteristics of visual light communication have steered the developers’ focus away from the security track. Such was the case with the IPv4 internet protocol suite, fiber-optics based networks, and more recently, with early adopted WLAN technologies. As the recent history of IT technological progress has taught us, a common mistake in the development of novel communication techniques has been to ignore or marginalize security issues. The common slogan summarizing VLC security features is: WYSIWYS-”What You See Is What You Send”. The directivity and high obstacle impermeability of optical signals are considered to provide a secure way to transmit data within an indoor environment, making the data difficult to intercept from outside. One of the areas in which VLC techniques are considered superior to traditional radio-based communication is security.

VLC has the potential to evolve into a general WLAN standard in with the OpenVLC platform, the authors have demonstrated that it is relatively easy with current software defined radio (SDR) toolkits to implement the TCP/IP suite on the VLC medium. The usage of smartphone cameras and light sensors brings VLC to the field of mobile computing and sensing.
VLC is also starting to be considered as a way of augmenting or even replacing RF networks for example, a wide range of techniques aimed at VLC based multimedia networks was developed under “hOME Gigabit Access” project (OMEGA) sponsored by the European Union. VLC systems also provide a safe alternative to electromagnetic interference from radio frequency communications in hazardous environments such as mines and petrochemical plants, and in applications where traditional WLAN communication may interfere with specialized equipment, for example in healthcare-especially in RF-restricted zones like emergency rooms and intensive care units -and in aeronautics.
Indoor applications include a range of communication facilities provided today by radio-based WLAN and Personal Area Networks (PAN), and range from: office communication, multimedia conferencing, peer-to-peer data exchange, data broadcasting-especially multimedia such as home-audio and video streams, see:, to positioning. VLC systems have been proposed and implemented both for indoor and outdoor applications-see and. VLC data transmission networks provide an attractive alternative to traditional wireless techniques. fail to deliver because of their bounded channel capacity and transmission rates due to the limited radio spectrum available.
As user demand for data transmission throughput and availability continues to increase, “traditional” radio-based communication systems, such as Wi-Fi, Bluetooth, ZigBee, etc. The decreasing cost and hence rapid adaptation of LED-based light make VLC a promising communication technique and a significant alternative to radio-based wireless communication. 21.Visible light communication (VLC) is a wireless optical communication technology through which baseband signals are modulated on the light emitted by an LED.
