Elevators are inseparable from urban life. After entering the elevator every day, the mobile phone signal will become very poor or even no signal. Usually, it doesn’t matter. It's a big threat, so how can the mobile phone signal be covered in the elevator?
Reasons for the poor elevator:
First of all, we need to know why the signal in the elevator is very poor? The propagation between the mobile phone and the base station relies on electromagnetic waves, and electromagnetic waves propagate in straight lines, and a large amount of energy will be lost when encountering thick obstacles. The elevator is an all-metal sealed space, and the sealed space itself will block the propagation of electromagnetic waves, and the all-metal structure makes electromagnetic waves almost impenetrable, which is the reason for the poor elevator signal.
According to the elevator level, choose different power cell phone signal booster www.booster-shop.com host, install outdoor signal receiving antenna in the place where the building is empty and the signal is good, connect the host through optical cable, and install signal transmission antenna in the elevator shaft. The elevator signal coverage can be completed. In this way, the signal coverage of the elevator is realized, so that the signal value in the elevator is full, and the emergency call can be called in time when the elevator fails, so that the rescuers can be dispatched in time to ensure the safety of the residents.
