<h1>Wireless Internet access via light bulbs</h1>
<p>Xinhua News reports that <strong>Professor Chi Nan</strong> of Shanghai's Fudan University has used a LED bulb to provide a high speed internet connection<br><br>She explained that by using Li-Fi technology a light bulb with embedded microchips can produce data rates as fast as 150 Mbps, much higher than the average broadband connection in China.<br>
<br>"Wherever there is an LED light bulb, there is an Internet signal," said Chi. "Turn off the light and there is no signal."<br><br>The term Li-Fi was coined by Harald Haas from the University of Edinburgh in the UK and refers to a type of visible light communication technology that delivers a networked, mobile, high-speed communication solution in a similar manner as WiFi. <br>
