The invention relates to a floor terminal for an elevator system in a building, comprising an elevator operating terminal and a wireless network device. The elevator operating terminal has a user interface for calling an elevator cabin, an elevator data interface for communicating data with an elevator controller, and a processing device which is coupled to the user interface and the elevator data interface. The wireless network device has a wireless transceiver for communicating with a communication device, a data interface for communicating data with the network access point, and a processing device coupled to the wireless transceiver and the data interface. By using such a floor terminal, a building can be equipped with additional functionality with relatively little installation effort during a redevelopment process.
