No (or limited) outdoor use

Li-Fi does not work in direct sunlight, so it cannot replace public Wi-Fi

Explore the benefits of Li-Fi

EfficientIf the light is on, data transmits—FREE

Energy consumptionThe benefits of faster wireless communication may not outweigh the costs of constantly keeping LED lights on

Blocked by wallsFor Li-Fi to work, LED light bulbs must be present and on

Security concernsThe minimum distance for signal reception is unclear, so it may be possible for a telephoto lens or optical sensor to intercept data

Maximum speed is unknownLi-Fi speeds were tested in controlled environments where light pollution and other variables weren’t present

SecureLight cannot pass through walls (Wi-Fi can)

Uses existing infrastructure14 billion light bulbs in the world = 14 billion opportunities to transmit data

Boosts internet capacityLi-Fi’s visible light spectrum is 10,000 times greater than Wi-Fi’s radio wave spectrum
