Photo - © Generated by AI. Dr. Alexey Yurasov, Professor of Physics and Mathematics at RТУ МИРЭА (MIPT), explained that mobile signal often fails in elevators due to the metal cabin, reinforced concrete shaft, and reflection of radio waves, reports Life.ru.
Consensus
- Mobile signal often drops in elevators.
- The loss of signal is due to the structure of the elevator cabin and shaft.
- Metallic components in the elevator reflect and block radio waves.
- Concrete structures further weaken signal transmission.
- Signal conditions change continuously as the elevator moves through different parts of a building.
- Higher-frequency signals are more affected by metal and concrete barriers.
Points of divergence
- Shamil Sultanov, member of the Association of Lawyers of Russia, stated that residents cannot voluntarily opt out of paying for elevators or garbage chutes because they are considered common property in multi-apartment buildings. — vm
