Abstract
In an optical wireless communication, OWC, network (), time division multiple access, TDMA, is commonly used for interference suppression among multiple network devices (D-Dn) associated to a single coordinator, or among adjacent coordinators (C-Cn). However, an offset of MAC cycles among two adjacent coordinators (C-C) may still result in interference to a network device (D) located in the overlapping area of the coverage areas of these two adjacent coordinators (C-Cn). This invention is directed to various methods, apparatus, systems, computer program and computer-readable media for providing a mechanism to make use of an out-of-band channel to send a signal from a network device (D) to the two adjacent coordinators (C-C), for assisting the alignment of MAC cycles among the two adjacent coordinators (C-C), and the out-of-band channel has a line-of-sight character, and is out-of-band as compared to the OWC network ().
