Wireless network for automation, realtime and/or industrial applications

摘要

The present invention describes a wireless network, in particular for automation, realtime and/or industrial applications, having at least two access network nodes and at least one radio station for wireless communication with at least one of the at least two access network nodes, wherein each of the at least two access network nodes uses a data channel selected from a set of available selectable data channels for wireless communication with a radio station assigned to it in each case, wherein a control communication channel which is distinct from the selectable data channels is provided in addition, and each of the at least two access network nodes is embodied for wirelessly sending information messages over the control communication channel and the at least one radio station is embodied for receiving the control communication channel.

1. A wireless network configured for at least one of automation, real-time and industrial applications, comprising:
a plurality of access network nodes, each of the plurality of access network nodes including a first transmit/receive unit for radio communication over a selected data channel and a second transmit unit for sending heartbeat messages configured as a beacon frame over a control communication channel; and at least one radio station for wireless communication with at least one of the plurality of access network nodes; wherein each of the plurality of access network nodes utilizes a data channel selected from a set of available selectable data channels for wireless communication with a radio station of the at least one radio station assigned to the each of the plurality of access network nodes; wherein the control communication channel is distinct from the selectable data channels, each of the plurality of access network nodes being configured for wirelessly sending the heartbeat messages configured as the beacon frame over the control communication channel, the beacon frame including an information element which identifies a sending access point as an access point having a separate management channel and simultaneously notifies a client of the selected data channel of the access point, and the at least one radio station being configured for receiving the control communication channel; and wherein the first transmit/receive unit is assigned a first antenna and the second transmit unit is assigned a second antenna, the first and second antennas having identical or similar antenna characteristics.
