5. SubmissionNorthumbria UniversitySlide 5 Lighting Performance Measured luminance level in the rooms receiving plane. Max ~ 440lx, Min ~ 280lx. These value meets ISO office illumination standard Measured SNR > 45dB doc.: IEEE 15-12-0639-00-0led November 2012

6. SubmissionNorthumbria UniversitySlide 6 10BASE VLC WLAN Performance 1. Link BER < 10 -9 at the standard luminous level 2. Ethernet throughput of VLC is equivalent to wired LAN system. Packet drop and delay are the same. 3. HD video streaming is successfully tested doc.: IEEE 15-12-0639-00-0led November 2012

7. SubmissionNorthumbria UniversitySlide 7 Conclusions Conclusion 10BASE WLAN based on VLC system is demonstrated for the office/room scale VLC system offers error free The system works with white light only, no blue filter is required (blue filter c auses significant signal power loss) No OFDM/DMT required (OFDM system cannot be used easily with Ethernet s ignal) Future work Demonstrate multiple-user/multiple-access scenario Work toward 100BASE WLAN VLC is on going doc.: IEEE 15-12-0639-00-0led November 2012
