- 1Li-Fi transmits data through ultra-low-frequency radio waves, reducing electromagnetic interference in high-density urban areas.
- 2Li-Fi is based on quantum entanglement of photons, enabling secure communication even in high-interference zones like industrial corridors.
- 3Li-Fi uses the visible and near-infrared light spectrum, which allows higher data transmission rates but limits operation to line-of-sight environments.✓
- 4Li-Fi uses millimeter waves which penetrate walls better than Wi-Fi, enhancing connectivity in remote rural areas.
Correct answer
Li-Fi uses the visible and near-infrared light spectrum, which allows higher data transmission rates but limits operation to line-of-sight environments.
