22. Li-Fi
What It Does: Uses Light To Communicate Wirelessly
Expected Rollout: Currently In Use
Based on the technology that is used for optical wireless networks, Li-Fi was introduced, in 2011, by a German professor of Mobile Communications named Harald Haas. It was designed to send data through light spectrums, thus transmitting using light instead of radio frequencies.

Initially, it was estimated that, by 2018, the market for Li-Fi would be worth north of $6 billion, however, as is evident by the general public’s lack of in-depth knowledge of Li-Fi, those projections didn’t quite come to fruition. With the ability to transmit at up to 100 gigabytes per second expect this tech to have its breakthrough sooner rather than later.
