一种利用灯光上网的新技术,即“lifi”正在多个国家的实验室里紧锣密鼓地研究,并将推广。近日,复旦大学也成功完成了这样一项实验,利用LED灯光上网下载速度达到3.7G/秒,这也创造了一项新的世界纪录。在这项新技术中,研究人员将网络信号接入一盏1W的LED灯珠,灯光下的4台电脑就能上网了,实验中,最高单向传输速率达到3.7G每秒,创造了可见光无
A new technology that utilizes light to access the Internet, “lifi ” is being intensively studied in laboratories in many countries and will be promoted. Recently, Fudan University also successfully completed such an experiment, the use of LED lights online download speed of 3.7G / sec, which also created a new world record. In this new technology, the researchers connected the network signal to a 1W LED lamp, and 4 computers in the light could access the Internet. In the experiment, the maximum unidirectional transmission rate reached 3.7G per second, creating visible light no
