| Abstract: | The development history and status of visible light communication technology are introduced. Then two latest achievements are reported. A 500 Mb/s real-time visible light communication system is reported, which, based on bandwidth expanding technology, uses a 1 watt fluorescent type LED as light source and PIN photodiode as detector, reaching a system bit error rate (BER) of 3.48×10-5 over a 6.2 meters transmission distance. Also reported is a new type of symmetrical 100 Mb/s VLC Ethernet system employing a 1 watt fluorescent type LED and PIN photodiode as devices, too. |
| Keywords: | visible light communication fluorescent type LED wireless optical communication visible light communication LiFi |
