1、 Elevator structure

2、 The signal does not cover this area

3、 Not installed

This is the reason why there is no signal in the elevator. Nowadays, most elevators are equipped with emergency buttons, which can be used in case of accidentsmobile phoneWithout a signal, pressing the button can still provide assistance. I believe that with the advancement of technology, signals will cover more elevators.

The first solution is to install wall mounted antennas and logarithmic antennas (usually one on two or three floors) on both sides of the elevator car to cover the elevator. Who is responsible for the elevator signal coverage? The wiring diagram of the building intercom system is trapped in the elevator for 15 minutes, and the property needs to compensate for the lack of signal in the community elevator.
