Abstract: An elevator, an elevator control unit and a method for transferring data in an elevator arrangement, the elevator arrangement including at least an elevator shaft, an elevator car configured to move in the elevator shaft and at least one wireless communication channel, such as a wireless network, available for communication in the elevator shaft. The method includes determining signal quality and/or data transmission quality of the at least one wireless communication channel in different positions of the elevator car in the elevator shaft, moving the elevator car to a position or area selected based on the determined signal quality and/or the determined data transmission quality, and performing data transfer at the selected area or at the selected position of the elevator car.

Abstract: According to an aspect, there is provided a signalization apparatus, the signalization apparatus comprising a first input module comprising a capacitive proximity sensing arrangement configured to detect a gesture from a user; a second input module comprising at least one signalization interface element and configured to detect an input from the user; an analysis module coupled to the first and the second input module and configured to analyze signals received from the first and the second input module to generate a control signal; and an interface coupled to the analysis module and configured to receive the control signal and provide the control signal to a controller.
