Not that I'm against you, but I can see some technical reasons why it "could" cause a problem.
Elevator control systems are no longer just a wall of clickety-clack relays with arcing contacts. They use microprocessors and low-voltage signalling. Reasonably strong RF could obscure the signals, or cause the controllers to do strange things. Since elevators are involved with public transportation and safety, you don't want the thing opening doors between floors, closing them on people, racing to the wrong floor, etc. All of this is potential danger to the occupants, and it could cause damage to the equipment. Of course, there are plenty of radio systems located in rooms separated from the elevator control equipment by one sheet-rock wall, and that is, of course, acceptable until they find out about it. Seems that if they don't know it's there, then it won't cause a problem. I remember a repeater site back in the early 70s. It was the 10th floor of a VA hospital. ALL the elevator equipment (probably installed in the 1950s) was up there: six motor-generators, six elevator traction motors, cable-driven followers that told the control system where the elevator was and how far it had moved when it neared its destination, a wall-full (7 ft high by 30 ft long) of 3-pole relays. Our equipment was located in one corner and the antenna was 10 ft above us. Not some place you wanted to go walking through with the lights turned off. Talk about sparks - the entire system used 120VDC on the relay contacts - and carbon dust - those commutators and brushes put out a lot of it. Somehow the repeater managed to survive the environment. Luckily, the repeater never had any effect on the elevator system. We always wanted to hook up a remote "Call" button to the system though; waiting for one of six elevators to decide which one would "race" up to the 10th floor was always a thrill.
