In an elevator, most people often have no contact. This is due to the fact that for stable communication, the smartphone must constantly exchange a signal with the nearest base station, and in an elevator this process is complicated by the design of the cabin and the shaft. Alexey Yurasov, Doctor of Physical and Mathematical Sciences, Professor of the Department of Nanoelectronics at RTU MIREA, spoke about this.
According to the expert, most modern elevators are a metal cabin that moves inside a reinforced concrete column with a large number of steel elements.
Metal reflects and blocks electromagnetic waves, and reinforced concrete weakens their passage. As a result, a less powerful signal reaches the phone than in an open space, Yurasov explained.
He added that while driving, reception conditions constantly change. The cabin passes through different parts of the building, and the radio signal is repeatedly reflected from metal walls, doors and column structures, and transmitted Life.ru.
According to Shamil Sultanov, a member of the Russian Bar Association, in most cases, it is impossible to refuse to pay for an elevator or a garbage chute at your request, since these items belong to the common ownership of an apartment building.
