Visible light communication

This vehicular network diagram example was drawn on the base of picture illustrating the post "LED Traffic Signals and Vehicle Lights for Optical Broadband Communications" from the blog "Terranautix".
"Visible Light Communication (VLC) is a rapidly emerging field that focuses on the use of light sources (between 400 THz and 800 THz) for the primary purpose of broadband communications. In order to transmit data over light, the light source (transceiver) is pulsed on and off rapidly to create a data stream, similar to fiber optic communications, but in the wireless form, or “Free-Space Optical Transmission“. By pulsing lights many thousands (and millions) of times per second, data transmission occurs at a rate undetectable by the human eye. Optical receivers convert the light pulses to an electronic signal on the receiver end. The Light Emitting Diode (LED) is the primary form factor currently undergoing extensive research."

The vehicular network diagram example "Visible light communication" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Vehicular Networking solution from the Computer and Networks area of ConceptDraw Solution Park.

The vector stencils library "Local vehicular networking" contains 88 symbols for drawing the vehicular computer telecommunication network diagrams using the ConceptDraw PRO diagramming and vector drawing software.
"A vehicular ad hoc network (VANET) uses cars as mobile nodes in a MANET to create a mobile network.[1] A VANET turns every participating car into a wireless router or node, allowing cars approximately 100 to 300 metres of each other to connect and, in turn, create a network with a wide range. As cars fall out of the signal range and drop out of the network, other cars can join in, connecting vehicles to one another so that a mobile Internet is created. It is estimated that the first systems that will integrate this technology are police and fire vehicles to communicate with each other for safety purposes. ...
Vehicular ad hocal networks are expected to implement wireless technologies such as dedicated short-range communications (DSRC) which is a type of Wi-Fi. Other candidate wireless technologies are cellular, satellite, and WiMAX. Vehicular ad hoc networks can be viewed as component of the intelligent transportation systems (ITS).
As promoted in ITS, vehicles communicate with each other via inter-vehicle communication (IVC) as well as with roadside base stations via roadside-to-vehicle communication (RVC)." [Vehicular ad hoc network. Wikipedia]
