Each consumer 21, 22, 23 is assigned its own output 34, 35, 36. Due to the selectivity of the switching device 3 and the assignment of the access attributes of the mobile devices 10, 11 to the exits 34, 35, 36, individual use of the office is possible. Eg the office is for meetings rentable. The rental price is dependent on the number of rented consumers 20 and on the determined length of time in which the consumers 20 remained in the second state.
