Abstract: This documents introduce the V2V CAMCOM design consideration for Vehicular Assistant Technology(VAT). This proposed LiFi / CamCom design consideration for VAT to operate on the application services like ITS, ADAS, etc on road condition. Also this can be used for IoT/IoL, LEDIT, Digital Signage with Advertisement Information etc..
Purpose: To Provided Concept models of Vehicle CamCom for VAT Interest Group

4. VAT V2V CAMCOM Design Parameters Considerations (1)
Noise Sources
CamCom system in ITS is largely affected by natural and artificial lights (noise and interference) such as Sunlight, ambient lights, road/street lights etc.
Issues Needs to be address in design
Minimizing the effect of external noise
Artificial or Natural
Ambient lights effect
Interference minimization
