WiFi将被淘汰？有光就能上网！一秒23部电影，比WiFi快百倍，5G的39倍
WiFi即将被淘汰？有光就能上网！一秒23部电影,比WiFi快100倍,5G的39倍
内容过于震撼，静下心来慢慢看。
我们都知道，无论我们现在手机功能有多强大，外观有多么的科幻，都少不了两样东西一是电，二是网络。
没有电和网络，手机就跟砖头没有什么的区别。实际上，不光光是我们的手机，目前什么智能设备哪能没有了网络呢！现在电视、电脑、汽车都需要连接到互联网不管是有线还是WiFi，当然除了手机网络外，我们用的最多的就是WiFi了。有同学说得好，我在家没有WiFi的日子一分一秒都过不下去，可是有没有想过，有一天WiFi会被更先进的技术所替代呢。
这不来自德国的科学家哈罗德-哈斯研发了一种新的无线传输标准，被公认为替代WiFi的下一代无线网络传输技术。他就是LIFI
LiFi是应用已铺设好的设备，外形相当于是led灯，通过在灯泡上放入一个微小的芯片，形成与WiFi热点相同功能的设备，使终端随时能够接入网络。该技术通过改变房间照明灯光线的闪烁频率进行数据传输的。只要在室内开启电灯不管什么网线路由什么都不需要，打开电灯你的手机电视等就能连上网络，据悉目前已经有公司是发布了这样的智能灯泡。
LIFL和WiFi最大的区别就是它并不像WiFi网络那样具有一定的范围。出了这个范围后，你的设备就会和WiFi网断开链接。除非你回到了这个网络范围内，那WiFi网络才会自动重新连接上。而LiFi就不同了，它是依靠光来传播的。理论上只要有光的地方连接上LiFi后，你就再也不会断网了。
LiFi技术简单来说就是一种，就是一种用光来传输信息，信号的无线技术。理论上的速度峰值可以达到224G/秒。
LiFi一秒可以达到27G，以现在的一部电影的大小来说，一秒可以下载23部电影。（与现在还没有广泛商用的的5G下载速度才700+M每秒）是5G网络的39倍，比WiFi快100倍。虽说LiFi仍然是一项正在进行研究完善中的技术。
但在中国的第一届国际智能产业博览会上，也在我们国家就发布了全世界第一款商品级超宽带可见光通信芯片组。这就是LiFi的首次国内亮相，而且根据相关负责人介绍。大众有望在两年内便可以体验到这项"黑科技"
