  • Method for configuring a wireless network and central station for a wireless network
    Publication number: 20160165455
    Abstract: A method for configuring a wireless network or a central station of a wireless network including at least the central station and at least two peripheral stations, includes in a first task, the central station ascertaining the peripheral stations which are reachable by wireless signals of the central station. In a second task, the central station configures at least one of the peripheral stations, which were ascertained in the first task, test-wise as a repeater, which receives and re-transmits the wireless signals of the central station. If the central station ascertains that more peripheral stations are reachable by the central station via the repeater, in a third task, the central station configures the peripheral stations, configured test-wise as repeaters, permanently as repeaters.
