A-QL stands for Asynchronous Quick Link, a two-dimensional multi-band color code sequential transmission protocol from a screen to camera. The A-QL is one of mode within the IEEE 802.15.7-2018 Optical Wireless Communication standard.
After the IEEE 802.15.7-2018 A-QL color code for Optical Camera Communication, 2D-OFDM is one of the next generation for Mbps data rate transmission from a screen TX to a camera.
We have measured the BER performance to compare 2D-OFDM and A-QL systems. The results showed that our systems can work within the distance of 4.5 meter and the viewing angle of 60-degree. Please download the PPT file for more details.
