Wireless communication using germicidal light frequencies is a system and method for transmitting and receiving data using Far-UVC light. The system communicates data using Far-UVC light of a germicidal wavelength. Far UV is a specific spectrum of UV light.

For time-division based wireless optical networks, it is important to keep neighboring coordinators synchronized to a common time base, in order to avoid interference to a network device located in the overlapping area of such neighboring coordinators. However, given that the common time base is located remotely, there is still timing synchronization uncertainty remaining at a coordinator side. A novel auxiliary scheduler subsystem, and the related methods and systems, are disclosed in this invention. By reserving time margins in the allocated time slots by the auxiliary scheduler subsystem, interference due to timing synchronization uncertainty is reduced.
