  3. 300MHz 300GHz 10GHz 3THz 428THz 750THz 300PHz RF IR visible UV 1m 3cm 100μm 700nm 400nm 1nm 1mm THz TC 48 802.15.3c VLC 802.11 802.16 IrDA VLC Introduction • VLC (Visible Light Communication) • New communication technology using “Visible Light” • Wavelength between ~400nm (750THz) and ~700nm (428THz) • General characteristic • Visibility : Aesthetically pleasing • Security : What You See Is What You Send • Unregulated : No regulation in optical frequency • Health : Harmless for human body • Non-interference with other devices

  4. Performance and Price comparison 2003 LED 100 2005 LED 10 Cost / Brightness ratio 2010 LED 1 Halogen Lamp Fluorescent Lamp 2015 HID (High-Intensity Discharge) LED Incandescent Lamp 150 0 50 100 Brightness / Power ratio Source: Credit Suisse, 2006.11.2 LED as Light Source for VLC • Relatively faster response time • Difficult to damage with external shock • High tolerance to humidity • Minimal heat generation • Light Emitting Diode (LED) • Small • Relatively Long life • More efficient • Low power consumption

  5. VLC Application Handheld device, Portable device CE, Kiosk, Printer

  6. VL vs. RF Characteristics

  7. Outline • Part 1 : What is VLC ? • VLC Introduction • VLC Application • LED as Light Source for VLC • VLC vs. RF characteristics • Part 2 : VL (Visible Light)-NFC • NFC Concept • NFC Application • Why VL-NFC ? • VL-NFC Characteristics • Conclusion

  8. Mode NFC Concept Feature • 10cm Communication • Smart Card + S/W + RFID • NFC Reader • NFC Tag • Peer to Peer Communication Samsung Electronics Co., Ltd. 7

  9. NFC Application e-Poster Kiosk P2P Payment Transportation Samsung Electronics Co., Ltd. 8

  10. Why VL-NFC ? High Data Rate VL-NFC High Data Rate Expansion of data rate capacity by not using frequency range VL NFC Visible Security What you see is what you send Visible Security Unregulated Unregulated No regulation in communication frequency

  11. VL-NFC Characteristics • High data rate (Link performance) 120 Mbps 240 Mbps 320 Mbps -log (BER)

  12. Outline • Part 1 : What is VLC ? • VLC Introduction • VLC Application • LED as Light Source for VLC • VLC vs. RF characteristics • Part 2 : VL (Visible Light)-NFC • NFC Concept • NFC Application • Why VL-NFC ? • VL-NFC Characteristics • Conclusion

  13. Conclusion • Visible Light-NFC has unique properties that opens up new applications and uses for NFC • High speed • Safe for interference sensitive situations • Visible evidence of security • Free from current radio regulation
