Assignee: SIGNIFY HOLDING B.V.
Field: Digital communication (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 0:
1. A system for handling interference in a wireless network comprising at least two coordinators and a plurality of devices selectively associated to a respective one of the coordinators,
wherein at least one of the coordinators is adapted to determine an own reserved period of a global time frame used for the transmissions and is further adapted to advertise its identifier and its determined own reserved period
wherein at least one of the devices is adapted to check whether an advertisement with an identifier has been received from a neighboring coordinator, to generate an interference report which comprises at least one of an identifier of an associated local coordinator and the identifier of the neighboring coordinator, and to report the interference report to the associated local coordinator or to the neighboring coordinator or to broadcast the interference report to all coordinators in its reach; and
wherein the at least one coordinator is further adapted to determine presence of a neighboring coordinator and its reserved period based on at least one of an interference report received from a reporting device of the devices and a report of the neighboring coordinator, and to control transmissions by at least one of limiting communication with the reporting device to its own reserved period in the global time-frame and limiting communication with other ones of the devices by excluding from the global time frame the reserved period of the neighboring coordinator reported by the reporting device or by the neighboring coordinator; and
wherein the wireless network is based on optical communication with line-of-sight character.
