Description: 如果世上每一顆燈泡都可以用來傳輸數據，那該會怎樣呢? 在 TEDGlobal 大會中，哈洛哈斯 (Harald Haas) 首度公開展示能夠實現這一理想的設備: 藉著從一個單一 LED 所發出的一閃一閃光線 (這種閃爍過於快速，肉眼看不見)，它可以傳送比基地台還要多的數據。它的方式更高效、更安全、也更普遍。

By harnessing the power of LED light bulbs, data can be transmitted using visible light, offering an alternative to crowded and inefficient radio waves. With 14 billion light bulbs already installed worldwide, this approach accesses a spectrum 10,000 times larger than what is currently used for wireless communication. A single LED lamp, modulated faster than the human eye can detect, can stream high-definition video and provide fast, secure connectivity. This method dramatically increases capacity, slashes energy waste, and protects privacy by confining data to illuminated spaces.
