A data communications network (10) for an aircraft (1) is provided. The data communications network comprises a first branch (200) for establishing a wireless data connection to a first group (301) of end devices, a primary control unit (100) connected to the first branch (200), and a backup control unit (110) connected to the first branch (200). The primary control unit (100) is configured for data transmission to and from the first group (301) of end devices via the first branch (200). The backup control unit (110) is configured for detecting an operating state of the primary control unit (100) and for taking over data transmission to and from the first group (301) of end devices via the first branch (200) from the primary control unit (100) in case of a failure of the primary control unit (100). |
