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.
For your convenience, we have measured the BER performance of A-QL code. The results showed that A-QL can support the transmission distance of 4.5m with the wide viewing angle of 60-degree. Please download the PPT file for more details.
