But as radio waves move this way, they have certain physical obstacles, such as walls, and therefore are weak.

In a situation when the mobile phone is unable to get a good signal from the base station or is out of range, it signals its signal, d.m. th More radiation, so you can talk.

This is most common in concrete or steel structures, but it is also in elevators, basements, and underground garages.

As the phone radiates mostly at the weak signal point, it is recommended to avoid its use in elevators, basements and other areas where the waves, or signal, tend to flow more.

Mobile phones work in a microwave ovenlike principle. For example, they radiate two to three times more powerful in an alley elevator or in a car than on the road, which can have health effects.

Also, instead of constantly calling your cell phone, you must send messages whenever possible. And if you are home, call through fixed lines or use headphones
