Outline• Networked VLC

– Social networking• Exchanging information• Local group chatting• Carpooling• Etc.

• Police and driving– Road accident, congestion– Driving violation

Social networking • In aircraft, hospital, cruise, train, bus,

etc.• Lights are connected internally through

a local network• People communicate with each other by

VLC hand devices via head/side lights– Share information in local virtual chatting

room although people may not know each other at first

– Playing with each other– Make friends– Carpool. People who are going to the

same destination may seek for the chance of carpooling

– Tourist group. People may self-organize a tourist group.

I am going to Hilton.Anyone Carpooling?

Count me in.

Technical requirements• Environment: indoor, outdoor• Bi-directional• Data type: text, image, data, etc. May support some

games not requiring high bandwidth• Data rate: low to medium• Latency: not stringent for text, some games such as

chess, poker, etc. May be stringent for some other games such as car racing.

• Distance: 1-5m• LED intensity: low to medium• Channel type: LOS• Beam pointing: manual, auto• Networked VLC

Police and driving (1/2)• Road accident.

– During an accident, police could send signal from car lights to the traffic lights, road lights, and/or the lights of the neighboring cars, for minimizing congestion.• Cars could be told to change lanes to

allow police cars to pass and/or avoid the accident

• Cars approaching to the accident spot could also be given alternative routes for detour to avoid congestion.

– The congestion report could be distributed further via lights of the car or traffic lights or road lights, etc.

Technical requirements

• Environment: outdoor• Bi-directional• Data type: text, image, data, etc. • Data rate: low to medium• Latency: not stringent for text, image, etc.• Distance: 1-10m• LED intensity: low to medium. Road light can

be high.• Channel type: LOS• Beam pointing: auto• Networked or/and ad-hoc VLC

Police and driving (2/2)• Driving violation

– Police can signal the specific car committing violation to stop or slow down, through the lights.

– Police can warn certain vehicles that they may be in danger of violating speed limits

– Drivers can signal back with explanation or information requested by the police

– Police may no longer be required to step out of their vehicles (safety)

– Police may signal and control the speed of the cars on violations (no high speed chases)

Speeding ticket. Drivers license, please.

with high velocity, the latency may be stringent• Distance: 1-10m• LED intensity: low to medium to high• Channel type: LOS• Beam pointing: auto, manual• Point to point VLC

Emergency• Via lights, ambulance could

signal the other cars and traffic lights.

• Emergency lights and exit lights– When emergency lights flashing,

in the building, or other places, directions to exit could be signaled by emergency lights or exit lights to mobile devices, so that people would not go to the dangerous place or in the way blocked.

– Whoever knows where the dangerous place or way blocked could signal to emergency lights or exit lights such information from mobile devices.

Blind navigation

• VLC could provide visual impairment aid– E.g., when a blind person tries to

across street, he/she may use hand device to try to find out whether the light is red or green. Once the signal is detected, the hand device would talk to the person about the traffic light status.

• VLC can provide location information in the absence of explicit signs– E.g., Street sign missing on the

roads

Selling in lights• Stores could utilize the lights in parking

lot, the lights from ceiling, etc., to sell content, such as DVD, e-book, music.– Stores can be e.g., Gas station, Grocery

store, etc.– People could set up the session to

download the e-content, then leave the car.

• In places such as squares, parks, etc., people can walk around and buy content from road lights or other lights– In pleasant weather, many people may

go out and walk around in evening, in parks or squares in cities

– People could download DVDs etc. from the nearby lights, to enjoy.


DVD, music, etc,

Guide and side information

• In places such as campus, stadium, …– Use the lights from ceiling, around

the building, or any available lights, to get the information of introduction of the building, inventory, etc.• Search the store directions,

sale/coupon information• History and directions of

buildings/landmarks in campus• Get the side information of the

players in stadium• Get the side information of the actor

and actress in a movie

Player’s information,Advertisement, Emergency guide,Etc.
