Today, our smartphones and telecom networks are incredibly sophisticated, providing us with fast internet and reliable connectivity. However, once we enter an elevator, our phones often seem to lose all functionality. This raises the question: with signals available all around us, what is it about elevators that disrupts them?

Why Do Signals Vanish Inside Elevators?
Mobile signals are essentially electromagnetic waves, and the materials used in elevator construction significantly hinder their transmission:

Metal Shielding: Elevators are typically constructed with layers of stainless steel, which can block or reflect radio waves, preventing signals from penetrating.

Concrete and Brick Walls: The elevator shaft is built from heavy concrete and bricks, materials that effectively obstruct radio waves, just as they block rain and snow.

Decorative Layers: The tiles, laminates, carpets, and wallpaper found inside elevators add further interference, complicating signal reception.

Can a Signal Booster Help?
Many believe that installing a signal booster in an elevator could resolve the issue. However, the effectiveness of this solution is not guaranteed. Providing adequate signal coverage in an elevator shaft is challenging. In buildings with multiple elevators or glass elevators on the exterior, boosters might offer some improvement, but their success largely depends on the booster’s quality and the shaft's design.

What to Do When You Lose Signal in an Elevator?
If you find yourself without a signal in an elevator, there's no need to worry. Your network will typically return once you exit the elevator, allowing you to use your phone as usual. If you happen to be stuck and your phone is unresponsive, utilize the elevator's intercom or emergency call button, as most modern elevators are equipped with this feature.
