Configuring wireless network using ephemeral gateway

A method for configuring a set of wireless network devices and at least one other gateway of a wireless network using a mobile configuration device, the method comprising:

• providing an ephemeral gateway located at a current position of the mobile configuration device, the ephemeral gateway configuring wireless network devices of the set of wireless network devices which are in proximity of the mobile configuration device, the ephemeral gateway acting as a gateway of the wireless network, and the ephemeral gateway making available for the at least one other gateway configuration information of the wireless network obtained during configuring the wireless network devices;
• wherein the ephemeral gateway is configured for providing security related information of the wireless network in the configuration information;
• wherein the ephemeral gateway is configured to:
• use at least a Zigbee communication protocol for configuring the wireless network devices,
• act as a temporary trust center that generates trust center link keys for the wireless network devices of the wireless network, and
• make available for the at least one other gateway trust center link key information about the trust center link keys as security related information in the configuration information in order to allow the at least one other gateway to use the trust center link keys or to arrive at own trust center link keys based on the trust center link key information made available by the ephemeral gateway, and
• wherein the ephemeral gateway configures the wireless network devices within a same zone or a single-hop distance of the current position of the mobile configuration device.
