Scientists will use LED hotspot to replace Wi-Fi wireless

According to foreign media reports, Boston University of Engineering Research on LED in the United States National Foundation for the help they point out that LED is not only the essential component of lighting system in the future, and will become the backbone of the next generation wireless network. According to the university professor Thomas Little said, at the time of LED "hot" network, TV, computer, iPhone, air conditioning and so on will be able to wireless communication, you only need a remote controller. To do this, you need the LED to build the communication network, which will be more reliable and free from electromagnetic interference. They are now studying the conversion of wireless signals into light energy. Little also added that this reform not only brought the light energy more efficiently, but also will become the key of the next generation wireless network, will build a high-speed network with low cost, low LED "hot spots" can reach 1 - 10 Mbps speed, better bandwidth can exceed the bandwidth of wireless communication of the existing LED network will be the nodes rely on a flash of light to transmit information, of course, the flashing naked eye is unable to distinguish, because light can not penetrate the LED wall of opaque objects so the signal can not be, can effectively prevent eavesdropping, improve security, signal receiving only in the PC or mobile phone equipped with a photosensitive element.
