Answer: With light.
Called MyLiFi, this lamp from Oledcomm uses Light Fidelity (Li-Fi) to deliver “controlled access to families, unprecedented confidentiality to professionals, a lag-free gaming experience, and radio wave-free internet to all,” according to the company.
Li-Fi works by modulating the light signals that LED lightbulbs emit, and then using those modulated signals to wirelessly transmit data. This makes the signal imperceptible and therefore highly secure, along with eliminating the need for radio or electromagnetic waves.
“Just as clean energies are displacing fossil fuels and propelling us towards a world of responsible innovation, light is now replacing radio waves to provide a safe, a people- and eco-friendly internet connection,” Oledcomm CEO Benjamin Azoulay told Digital Trends. “MyLiFi marks the start of a new era in connectivity.”
