What do these big numbers mean in terms of content?
By NASA
6 This leads to a gap between supply and demand
1 Exabyte = 1000 Petabyte
7 The radio spectrum does not provide enough room to grow.
8 What is blocking this need?
9 Lighting can provide additional spectrum to communicate
Visible

Hz
10 Visible Light Communications (VLC) Infrared (IR)
There are two variants for Optical Wireless Communications (OWC) Coded light LiFi
One-way communication Two-way communication Transmits identifier/code - low data rate Broadband - high data rate Data reception via smartphone camera Data reception via USB access key /dongle Designed to provide indoor localization Designed to provide broadband wireless internet
11 Advantages of Li-Fi
Secure Reliable/Fast No Radio Waves We want to work wirelessly but safety is We want a stable connection despite several crucial for our business line. We want a stable data rate per user despite the number of users. RF sensitive areas with poor or no Wi-Fi.
Li-Fi offers a strict definition of your Li-Fi ‘offloads’ Wi-Fi in high traffic areas. Li-Fi offers a high quality (non-interfering) communication area. connection
