There are two variants for Optical Wireless Communications (OWC)
Visible Light Communications (VLC) Infrared (IR)
One-way communicationTransmits identifier/code - low data rateData reception via smartphone cameraDesigned to provide indoor localization
Two-way communicationBroadband - high data rate
Data reception via USB access key /dongleDesigned to provide broadband wireless

Advantages of Li-Fi
Secure
We want to work wirelessly but safety is crucial for our business line.
Li-Fi offers a strict definition of your communication area.
Corporate Banking & government Hospitality areas
Reliable/Fast
We want a stable data rate per user despite the number of users.
Li-Fi ‘offloads’ Wi-Fi in high traffic areas.
Corporate
IndustryMilitary
Industry Schools
No Radio Waves
We want a stable connection despite several RF sensitive areas with poor or no Wi-Fi.
Li-Fi offers a high quality (non-interfering) connection
