Abstract
In a LiFi network with multiple coordinators, interference in the overlapping areas between the local parts of the network can occur if each coordinator determines its own local time schedule for communicating with devices. To solve this problem, the invention proposes cooperation between the coordinators to determine non-interfering local time schedules whereby the coordinators rely on interference reports from the devices in the overlapping areas and apply a small number of simple rules. The proposed method is simple, scalable and independent from a central unit.
