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.
