Abstract: A system and a method may be used for operating and/or calibrating a transmitter device. The system and method may include wirelessly transmitting a radio signal with identification data specific to the transmitter device and reference data. The transmitter device may transmit the radio signal with signal properties at least partially dependent on the reference data. A communication device may receive the radio signal and ascertain a distance between the transmitter device and the communication device using reception-side signal properties and the reference data ascertained from the received radio signal. A distance sensor may detect a distance between the transmitter device and the communication device. An evaluation unit may ascertain the reference data depending on the reception-side signal properties of the radio signal and the detected distance and to provide the ascertained reference data in the transmitter device for calibrating the transmitting device.

Abstract: A method for controlling at least one wireless network access point in a building may include detecting whether a wireless communication device is connected to at least one wireless network access point and/or whether a person is present using a group of presence detectors. An illumination system may include at least one wireless network point and/or the group of presence detectors. An activated network access point may remain activated when the wireless network access point is connected to a wireless communication device and/or when a person is present. A network access point may be automatically deactivated when the wireless network access point is not connected to a wireless communication device and/or when a person is not present. A deactivated network access point may be automatically reactivated when the wireless network access point is connected to a wireless communication device and/or when a person is present. Combinations thereof are also possible.
