Abstract:
1. A method for controlling a network system, the network system including a wireless network to which a client is wirelessly connected, a backbone network that is directly connected to the wireless network, and a client control device connected to the backbone network, the method having the following steps: establishing a tunnel, which is a packet data connection based on a tunneling protocol, between the client control device and the client via the backbone network for transmitting data between the client control device and the client, wherein the client control device transmits Ethernet telegrams and/or Ethernet packets between the client and the backbone network via the tunnel, such that the client control device bridges Ethernet telegrams and/or Ethernet packets from the client into the backbone network and the client control device delivers Ethernet telegrams from the backbone network via the tunnel to the client, and wherein the client control device logically represents a switch having an end point of the tunnel as switch port; transmitting status information from the client to the client control device through the tunnel via the backbone network; evaluating the transmitted status information using the client control device, wherein the client control device on the basis of the evaluated status information makes decisions for coordination of the client; and transmitting a control signal for controlling the client, which depends on the evaluated status information, from the client control device to the client through the tunnel via the backbone network; wherein a transmitting power of the client, a roaming threshold, or the modulation types to be used are controlled via the transmitted control signal; and wherein at least one additional client is connected to the wireless network, and an additional tunnel is established between the client control device and the additional client for transmitting data between the client control device and the additional client.
