SUMMARY
Telecom operators assert that users can receive network coverage inside elevators, despite elevators being metal structures that act as closed conductors. According to Gauss' theorem, no charge exists within a closed conductor, leading to confusion about signal reception. However, cell phones operate using electrodynamics, allowing electromagnetic waves to transmit signals. While elevators do attenuate some signals, they do not completely block them, particularly at specific frequencies where signals can penetrate the elevator walls effectively.
