Ring Network Topology

This vehicular network diagram sample 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 "Landmarks" contains 34 signs and pictograms for drawing road and transit maps.
The vector stencils library "Map symbols" contains 10 signs and pictograms for drawing road and transit maps.
"A landmark is a recognizable natural or man-made feature used for navigation, a feature that stands out from its near environment and is often visible from long distances.
In modern use, the term can also be applied to smaller structures or features, that have become local or national symbols." [Landmark. Wikipedia]
The pictograms example "Design elements - Location map" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Spatial Infographics solution from the Maps area of ConceptDraw Solution Park.
