Abstract
A wireless data network, which covers a first physical area and has a wireless node is increased by generating access control information for the wireless data network. The access control information is communicated to a second wireless network associated with a mains power supply, e.g. a lighting circuit, operative in at least one part of the first physical area located within a secure environment. The access control information is transmitted to the wireless node using the second wireless network. The access control information is changed from time to time (preferably at predetermined intervals). The preceding steps are repeated for each change.
